I would like to remove a certain text from an HTML page using XSLT. The text I would like to remove is <h2>OLD TEXT</h2>. I'm trying to remove it by replacing the text with an empty string but I don't get it to work.
When calling my string-replace-all function with "<h2>OLD TEXT</h2>" text as input I get the following error:
The value of the attribute "select" associated with an element type "xsl:with-param" must not contain the '<' character.
When calling my string-replace-all function with just "OLD TEXT" as input the text gets replaced but the output
is no longer HTML, it's just plain text without the HTML tags.
How could I do to replace <h2>OLD TEXT</h2> and still get the output in HTML format?
My code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" />
<xsl:template name="string-replace-all">
<xsl:param name="text" />
<xsl:param name="replace" />
<xsl:param name="by" />
<xsl:choose>
<xsl:when test="$text = '' or $replace = ''or not($replace)" >
<!-- Prevent this routine from hanging -->
<xsl:copy-of select="$text" />
</xsl:when>
<xsl:when test="contains($text, $replace)">
<xsl:copy-of select="substring-before($text,$replace)" />
<xsl:copy-of select="$by" />
<xsl:call-template name="string-replace-all">
<xsl:with-param name="text" select="substring-after($text,$replace)" />
<xsl:with-param name="replace" select="$replace" />

What have I done wrong here?
Your first problem is that you are testing this code in an environment that gives very poor diagnostics. Ideally, test your code in an XSLT development tool such as Oxygen. If you can only test it in the browser, use a browser like Chrome with a decent developer's console.
When I run it in XSLTfiddle (https://www.xsltfiddle.liberty-development.net) I get a clear error message:
Error executing XSLT at line 70 : An attribute node (dir) cannot be
created after a child of the containing element. Most recent element
start tag was output at line 58 of module
If you look at the surrounding code:
<div class="fieldCounsel">
<xsl:choose>
<xsl:when test="#ItemPosition='1' and Assistant!=''">
<xsl:text>1st: </xsl:text>
</xsl:when>
<xsl:when test="#ItemPosition='2'">
<xsl:text>2nd: </xsl:text>
</xsl:when>
<xsl:when test="#ItemPosition='3'">
<xsl:text>3rd: </xsl:text>
</xsl:when>
</xsl:choose>
<xsl:attribute name="dir">
<xsl:value-of select="//Settings/Direction"/>
</xsl:attribute>
<xsl:value-of select="StudyPoint"/>
</div>
It's perfectly clear that the xsl:choose is creating a text node, and you then follow this with an instruction that creates an attribute. You need to create the attributes of an element before you create the children.
I am fairly new to xml and I'm having a weird problem with templates. For empty data nodes, instead of displaying a blank space where the data should be, I want to display a message like 'None Found' or 'No Data' on an html page. I have done both an xsl:choose statement and 2 xsl:if statements with no success. I already know this particular node is empty, I just want to show a message instead of a blank space. The Otherwise or False statements just don't seem to run at all. Please help!! What am I doing wrong here?

Change the template match="Root/findings/dobs" to this:
<xsl:template match="Root/findings/dobs">
<p>
<xsl:for-each select="dob">
<xsl:variable name="dobHasData" select="boolean(normalize-space(.))"/>
<xsl:choose>
<xsl:when test="$dobHasData">
<ul><xsl:apply-templates select="data"/></ul>
</xsl:when>
<xsl:otherwise>
<xsl:text>None found</xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</p>
</xsl:template>
Or even more template matching like:
<xsl:template match="Root/findings/dobs">
<p>
<xsl:apply-templates select="dob"/>
</p>
</xsl:template>
<xsl:template match="dob">
<xsl:variable name="dobHasData" select="boolean(normalize-space(.))"/>
<xsl:choose>
<xsl:when test="$dobHasData">
<ul><xsl:apply-templates select="data"/></ul>
</xsl:when>
<xsl:otherwise>
<xsl:text>None found</xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
And this last template could also be splitted in two short ones:
<xsl:template match="dob[normalize-space(.)]">
<ul><xsl:apply-templates select="data"/></ul>
</xsl:template>
<xsl:template match="dob[not(normalize-space(.))]">
<xsl:text>None found</xsl:text>

It's returning this:
Daisy
2016-02-29
0
This is what I expected it to output:
Daisy
2016-02-29
1
But it isn't returning the one. Why?
Do I have to exit the template //videos_pub?
If so, how do I do it?
I realized by doing the :
<xsl:with-param name="id" select="//video/#id"/>
I was selecting the node itself not the value of the "//video/#id" expression.
I fixed it by doing this:
<xsl:with-param name="id">
<xsl:value-of select="//video/#id"/>
</xsl:with-param>
Now my paramhas the value of the node //video/#id.
Thank you all for your answers.
You are overusing the // syntax, which is a "brute force" way of using XPath when you're not sure of a better way. You're also using "going around your elbow to get to your ***" expressions like //video[#id= $id]/./#data.
Also, I assume you want to output info for all of the videos, not just the first one.
Here is how you would do that, without all the sloppy stuff:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml">
<xsl:output method="xml" version="1.0" encoding="UTF-8"
indent="yes" />
<xsl:output doctype-public="-//W3C//DTD XHTML 1.1//EN"
doctype-system="http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd" />
<!-- <xsl:imports href="1.xsl"/> -->
<xsl:template match="/">
<html>
<head>
<title>2.</title>
</head>
<body>
<ul>
<xsl:apply-templates select="xml_tube/videos_pub/video"/>
</ul>
<!-- <xsl:apply-templates select="//comentarios"/> -->
</body>
</html>
</xsl:template>
<xsl:template match="video">
<li>
<xsl:call-template name="publisher">
<xsl:with-param name="video" select="."/>
</xsl:call-template>
<xsl:call-template name="data">
<xsl:with-param name="video" select="."/>
</xsl:call-template>
<xsl:call-template name="comment">
<xsl:with-param name="id" select="#id"/>
</xsl:call-template>
</li>
</xsl:template>
<xsl:template name="publisher">
<xsl:param name="video"/>
<p>
<xsl:value-of select="$video/#publisher"/>
</p>
</xsl:template>
<xsl:template name="data">
<xsl:param name="video"/>
<p>
<xsl:value-of select="$video/#data"/>
</p>
</xsl:template>
<xsl:template name="comment">
<xsl:param name="id"/>
<p>
<xsl:value-of select="count(/xml_tube/comentarios/comentario[#refV = $id])" />
</p>
</xsl:template>
</xsl:stylesheet>
And if you want to make it really efficient, you can use an xsl:key to help count the comments:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml">
<xsl:output method="xml" version="1.0" encoding="UTF-8"
indent="yes" />
<xsl:output doctype-public="-//W3C//DTD XHTML 1.1//EN"
doctype-system="http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd" />
<xsl:key name="kVideoComments" match="comentario" use="#refV" />
<!-- <xsl:imports href="1.xsl"/> -->
<xsl:template match="/">
<html>
<head>
<title>2.</title>
</head>
<body>
<ul>
<xsl:apply-templates select="xml_tube/videos_pub/video"/>
</ul>
<!-- <xsl:apply-templates select="//comentarios"/> -->
</body>
</html>
</xsl:template>
<xsl:template match="video">
<li>
<xsl:call-template name="publisher">
<xsl:with-param name="video" select="."/>
</xsl:call-template>
<xsl:call-template name="data">
<xsl:with-param name="video" select="."/>
</xsl:call-template>
<xsl:call-template name="comment">
<xsl:with-param name="id" select="#id"/>
</xsl:call-template>
</li>
</xsl:template>
<xsl:template name="publisher">
<xsl:param name="video"/>
<p>
<xsl:value-of select="$video/#publisher"/>
</p>
</xsl:template>
<xsl:template name="data">
<xsl:param name="video"/>
<p>
<xsl:value-of select="$video/#data"/>
</p>
</xsl:template>
<xsl:template name="comment">
<xsl:param name="id"/>
<p>
<xsl:value-of select="count(key('kVideoComments', $id))" />
</p>
</xsl:template>
</xsl:stylesheet>
Both of these output:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

I need wrapping each word with a tag (e. span) in a HTML document, like:
<html>
<head>
<title>It doesnt matter</title>
</head>
<body>
<div> Text in a div </div>
<div>
Text in a div
<p>
Text inside a p
</p>
</div>
</body>
</html>
To result something like this:
<html>
<head>
<title>It doesnt matter</title>
</head>
<body>
<div> <span>Text </span> <span> in </span> <span> a </span> <span> div </span> </div>
<div>
<span>Text </span> <span> in </span> <span> a </span> <span> div </span>
<p>
<span>Text </span> <span> in </span> <span> a </span> <span> p </span>
</p>
</div>
</body>
</html>
It's important to keep the structure of the body...
Any help?
All of the three different solutions below use the XSLT design pattern of overriding the identity rule to generally preserve the structure and contents of the XML document, and only modify specific nodes.
I. XSLT 1.0 solution:
This short and simple transformation (no <xsl:choose> used anywhere):
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[not(self::title)]/text()"
name="split">
<xsl:param name="pText" select=
"concat(normalize-space(.), ' ')"/>
<xsl:if test="string-length(normalize-space($pText)) >0">
<span>
<xsl:value-of select=
"substring-before($pText, ' ')"/>
</span>
<xsl:call-template name="split">
<xsl:with-param name="pText"
select="substring-after($pText, ' ')"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
when applied to the provided XML document:
<html>
<head>
<title>It doesnt matter</title>
</head>
<body>
<div> Text in a div </div>
<div>
Text in a div
<p>
Text inside a p
</p>
</div>
</body>
</html>
produces the wanted, correct result:
<html>
<head>
<title>It doesnt matter</title>
</head>
<body>
<div>
<span>Text</span>
<span>in</span>
<span>a</span>
<span>div</span>
</div>
<div>
<span>Text</span>
<span>in</span>
<span>a</span>
<span>div</span>
<p>
<span>Text</span>
<span>inside</span>
<span>a</span>
<span>p</span>
</p>
</div>
</body>
</html>
II. XSLT 2.0 solution:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[not(self::title)]/text()">
<xsl:for-each select="tokenize(., '[\s]')[.]">
<span><xsl:sequence select="."/></span>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
when this transformation is applied to the same XML document (above), again the correct, wanted result is produced:
<html>
<head>
<title>It doesnt matter</title>
</head>
<body>
<div>
<span>Text</span>
<span>in</span>
<span>a</span>
<span>div</span>
</div>
<div>
<span>Text</span>
<span>in</span>
<span>a</span>
<span>div</span>
<p>
<span>Text</span>
<span>inside</span>
<span>a</span>
<span>p</span>
</p>
</div>
</body>
</html>
III Solution using FXSL:
Using the str-split-to-words template/function of FXSL one can easily implement much more complicated tokenization -- in any version of XSLT:
Let's have a more complicated XML document and tokenization rules:
<html>
<head>
<title>It doesnt matter</title>
</head>
<body>
<div> Text: in a div </div>
<div>
Text; in; a. div
<p>
Text- inside [a] [p]
</p>
</div>
</body>
</html>
Here there is more than one delimiter that indicates the start or end of a word. In this particular example the delimiters can be: " ", ";", ".", ":", "-", "[", "]".
The following transformation uses FXSL for this more complicated tokenization:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ext="http://exslt.org/common"
exclude-result-prefixes="ext">
<xsl:import href="strSplit-to-Words.xsl"/>
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[not(self::title)]/text()">
<xsl:variable name="vwordNodes">
<xsl:call-template name="str-split-to-words">
<xsl:with-param name="pStr" select="normalize-space(.)"/>
<xsl:with-param name="pDelimiters"
select="' ;.:-[]'"/>
</xsl:call-template>
</xsl:variable>
<xsl:apply-templates select="ext:node-set($vwordNodes)/*"/>
</xsl:template>
<xsl:template match="word[string-length(normalize-space(.)) > 0]">
<span>
<xsl:value-of select="."/>
</span>
</xsl:template>
</xsl:stylesheet>
and produces the wanted, correct result:
<html>
<head>
<title>It doesnt matter</title>
</head>
<body>
<div>
<span>Text</span>
<span>in</span>
<span>a</span>
<span>div</span>
</div>
<div>
<span>Text</span>
<span>in</span>
<span>a</span>
<span>div</span>
<p>
<span>Text</span>
<span>inside</span>
<span>a</span>
<span>p</span>
<word/>
</p>
</div>
</body>
</html>
You could achieve this by extending the identity transform to include a recursive template which checks for spaces in a piece of text, and if so puts a span tag around the first word. It can then recursively calls itself for the remaining portion of the text.
Here is it in action...
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes"/>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<!-- Don't split the words in the title -->
<xsl:template match="title">
<xsl:copy-of select="." />
</xsl:template>
<!-- Matches a text element. Given a name so it can be recursively called -->
<xsl:template match="text()" name="wrapper">
<xsl:param name="text" select="." />
<xsl:variable name="new" select="normalize-space($text)" />
<xsl:choose>
<xsl:when test="contains($new, ' ')">
<span><xsl:value-of select="concat(substring-before($new, ' '), ' ')" /></span>
<xsl:call-template name="wrapper">
<xsl:with-param name="text" select="substring-after($new, ' ')" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<span><xsl:value-of select="$new" /></span>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
When called on your sample HTML, the output is as follows:
<html>
<head>
<title>It doesnt matter</title>
</head>
<body>
<div>
<span>Text </span>
<span>in </span>
<span>a </span>
<span>div</span>
</div>
<div>
<span>Text </span>
<span>in </span>
<span>a </span>
<span>div</span>
<p>
<span>Text </span>
<span>inside </span>
<span>a </span>
<span>p</span>
</p>
</div>
</body>
</html>
I wasn't 100% sure how important the spaces within the span elements are for you though.
So I have a XML document generated by my application like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE AddressBook>
<?xml-stylesheet type="text/xsl" href="stylesheet.xsl"?>
<AddressBook>
<Item>
<UserGeneratedElementName1 class="info">Whatever blah blah</UserGeneratedElementName1>
<UserGeneratedElementName2 class="info">Whatever blah blah</UserGeneratedElementName2>
</Item>
<Item>
<UserGeneratedElementName3 class="info">Whatever blah blah</UserGeneratedElementName3>
</Item>
...
...
Other Items with user-generated elements with user-generated content...
</AddressBook>
And I want to turn it into a HTML document similar to this:
<html>
<head>
<title>AddressBook</title>
</head>
<body>
<div class="root">
<div class="item">
<b>UserGeneratedElementName1:</b> Whatever blah blah
<b>UserGeneratedElementName2:</b> Whatever blah blah
</div>
<div class="item">
<b>UserGeneratedElementName3:</b> Whatever blah blah
</div>
...
...
Other transformed items...
</div>
</body>
</html>
I have tried to get a grasp of the XSLT syntax, but all the guides were either too vague to help me with this or too deep. Also XSLT syntax seems quite confusing.
Thanks in advance.
Take a look at this question here
Is there an XSLT name-of element?
You can use
<xsl:value-of select ="name(.)"/>
or
<xsl:value-of select ="local-name()"/>
to get the name of a node, depending on if you want to include the full prefixed name, or just the local portion.
You should be able to piece those together with xsl:for-each blocks to iterate through the first 3 levels of items and generate the HTML you're looking for.
Something like this would work for a fixed number of levels.
<xsl:for-each select="*">
<html>
<head>
<title><xsl:value-of select="local-name()" /></title>
</head>
<body>
<div class="root">
<xsl:for-each select="*">
<div>
<xsl:attribute name="class">
<xsl:value-of select="local-name()" />
</xsl:attribute>
<xsl:for-each select="*">
<b><xsl:value-of select="local-name()" />:</b> <xsl:value-of select="." />
</xsl:for-each>
</div>
</xsl:for-each>
</div>
</body>
</html>
</xsl:for-each>
A more generic approach would look something more like:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="html" indent="yes" version="4.0"/>
<xsl:template match="/">
<xsl:for-each select="*">
<html>
<head>
<title><xsl:value-of select="local-name()" /></title>
</head>
<body>
<div class="root">
<xsl:call-template name="recurseElement">
<xsl:with-param name="element" select="." />
</xsl:call-template>
</div>
</body>
</html>
</xsl:for-each>
</xsl:template>
<xsl:template name="recurseElement">
<xsl:param name="element" />
<xsl:for-each select="$element/*">
<xsl:choose>
<xsl:when test="count(child::*)>0">
<div>
<xsl:attribute name="class">
<xsl:value-of select="local-name()" />
</xsl:attribute>
<xsl:call-template name="recurseElement">
<xsl:with-param name="element" select="." />
</xsl:call-template>
</div>
</xsl:when>
<xsl:otherwise>
<b><xsl:value-of select="local-name()" />:</b> <xsl:value-of select="." />
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
This complete XSLT transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="AddressBook">
<html>
<head>
<title>AddressBook</title>
</head>
<body>
<div class="root">
<xsl:apply-templates/>
</div>
</body>
</html>
</xsl:template>
<xsl:template match="Item">
<div class="item"><xsl:apply-templates/></div>
</xsl:template>
<xsl:template match="Item/*">
<b><xsl:value-of select="name()"/>:</b> <xsl:text/>
<xsl:value-of select="concat(.,'
')"/>
</xsl:template>
</xsl:stylesheet>
when applied on the provided XML document:
<AddressBook>
<Item>
<UserGeneratedElementName1 class="info">Whatever blah blah</UserGeneratedElementName1>
<UserGeneratedElementName2 class="info">Whatever blah blah</UserGeneratedElementName2>
</Item>
<Item>
<UserGeneratedElementName3 class="info">Whatever blah blah</UserGeneratedElementName3>
</Item> ... ... Other Items with user-generated elements with user-generated content...
</AddressBook>
produces the wanted, correct result:
<html>
<head>
<title>AddressBook</title>
</head>
<body>
<div class="root">
<div class="item">
<b>UserGeneratedElementName1:</b>Whatever blah blah
<b>UserGeneratedElementName2:</b>Whatever blah blah
</div>
<div class="item">
<b>UserGeneratedElementName3:</b>Whatever blah blah
</div> ... ... Other Items with user-generated elements with user-generated content...
</div>
</body>
</html>
Explanation:
Templates matching any Item element and any element child of an Item element.
Use of the standard XPath name() function.
