I am trying to display an JPG image in HTMl after conversion to base64. This operation I am trying in XSLT code. Couple of options I tried with concat and write-binary, but none of them seem to be working.
Is this supported using XSLT? Is there any built-in function available?
<img>
<xsl:attribute name="src">
<!--xsl:value-of select="concat('data:image/gif;base64,',xPath)"/-->
<xsl:value-of select="file:write-binary(C:\MyDesktop\Desktop\allImages\download.jpg, xs:base64Binary(string()))"/>
</xsl:attribute>
</img>
Assuming you have access to e.g. Saxon PE or EE with support for the EXPath file module http://expath.org/spec/file then I think it suffices to construct a data URI https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs using the file:read-binary method http://expath.org/spec/file#fn.read-binary:
In the XSLT you can use e.g.
<img src="data:image/jpeg;base64,{file:read-binary('C:\MyDesktop\Desktop\allImages\download.jpg')}"/>
to construct an HTML img element that has the image data inlined in the data URI set as the src attribute value.
The stylesheet obviously needs to declare the module's namespace with e.g.
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:file="http://expath.org/ns/file"
exclude-result-prefixes="#all" version="3.0">

I'm new to XSLT.
I need to apply floating text that displays a setting for acronyms, as soon as the mouse cursor hovers over a word that is abbreviated.
My input file is XML, and every word that should display acronyms is represented in the following format:
<abbreviation Id="E.G."/>
When the mouse cursor hovers over the word EG, the floating text will be displayed: "for example".
I thought to apply the floating text using the HTML abbr tag
And the code I wrote is:
<xsl:template match="abbreviation">
<abbr title="for example.">
<xsl:value-of select="#Id"/>
</abbr>
</xsl:template>
I want the "title" attribute to be given as a parameter the definition of the main boxes from an external file that will contain a dictionary of related abbreviations and explanations.
I would love to know how to apply my issue.
And also get ideas about the external dictionary file - what kind of file should you create? For example, I would like a good structure of the file.
Note:
I use OXYGEN EDITOR,
And I believe I can also get solutions in XSLT version 2 and 3
Suppose your external dictionary looks like:
dict.xml
<dictionary>
<entry abbr="C.V.">course of life</entry>
<entry abbr="E.G.">for example</entry>
<entry abbr="N.B.">note well</entry>
</dictionary>
You can then use a key to transform an input like:
XML
<root>
<abbreviation Id="E.G."/>
</root>
using:
XSLT 2.0 (untested)
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="path-to-dictionary" select="'dict.xml'"/>
<xsl:key name="abbr-lookup" match="entry" use="#abbr" />
<xsl:template match="/root">
<html>
<body>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>
<xsl:template match="abbreviation">
<abbr title="{key('abbr-lookup', #Id, document($path-to-dictionary))}">
<xsl:value-of select="#Id"/>
</abbr>
</xsl:template>
</xsl:stylesheet>
to get:
Result
<html>
<body>
<abbr title="for example">E.G.</abbr>
</body>
</html>
To understand the syntax used, read about Attribute Value Templates.
Well, XSLT does not float any text, it is a programming language to transform XML (or with XSLT 2 or 3, other input formats) to XML, (X)HTML, plain text. You seem to want to transform your XML to HTML in the hope the HTML user agent or browser displays a tooltip of the title attribute.
As for using an XML file as a secondary input file, if you have abbrvs.xml with
<root><abbr key="E.G.">for example.</abbr>...</root>
then in XSLT you can use
<abbr title="{key('abbr', #Id, doc('abbrvs.xml'))}">
<xsl:value-of select="#id"/>
</abbr>
to pull that title attribute value from the secondary input file if the XSLT declares a key
<xsl:key name="abbr" match="abbr" use="#key"/>
I would like to do some XSLT conversion with the HTML page with YQL. The following line is used to get HTML:
select * from html where url="http://example.com/somepage" and
xpath='//div[#class="article-text"]'
How can I apply select * from xslt where ... to the previous result?
Not sure as I haven't used YQL before, but I guess you have to go the other way round: using XSLT to get the result out of the HTML and than apply the YQL-Query to get the XML as result:
XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<xsl:apply-templates select="//div[#class='article-text']" />
</xsl:template>
<xsl:template match="div[#class='article-text']">
<articletext>
<xsl:value-of select="."/>
</articletext>
</xsl:template>
YQL query:
select * from xslt where stylesheet="url/name-of.xsl" and
url="http://example.com/somepage"
This should result in
<results>
<articletext>Text of article</articletext>
</results>
As I don't know YQL but was used working with XSLT/XPath, I just googled about it and found this recommendable SO example: YQL column projection using XPATH . Instead of just pasting the link I adjusted the XSLT-Part of the example provided there to match your query.
Note that HTML is not an XML-based language (though XHTML is). If you want to operate on HTML using XML tools, you will need to either find an HTML parser (such as nekohtml, which is based on Apache Xerces) or preconvert the HTML to XHTML using something like the W3C's tidy tool.
I tried to transform a XML document within a web browser to HTML via two XSL transformations.
Long story short: XML => XML => HTML
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<?xml-stylesheet type="text/xsl" href="enrich.xsl" ?>
<?xml-stylesheet type="text/xsl" href="overview.xsl" ?>
<project></project>
The first XSL should add some elements to the XML,
the second XSL should transform the result from the first step to HTML.
My target is to get HTML displayed at the end.
Both XSL are transformed separately.
It seems to me that Safari, Firefox and Chrome do not execute more than one processing instruction. Is this true, or am i missing something?
I never tried to execute two seperate transformations in a web browser, but you may try this kind of patterns to do "2 transforms in 1" (this only works with XSLT 2.0, cause of the variable structure) :
<xsl:template match="/">
<!-- You use a variable to store the result of the first transformation.-->
<xsl:variable name="result1">
<!-- You use a mode called transform1 (or whatever) to distinct templates for
transform1 from those of transform2-->
<xsl:apply-templates select="*" mode="transform1"/>
</xsl:variable>
<!-- You execute the second transform on the result variable (you could use a
mode to formally distinct the template from transform2, or you could use default
mode for them) -->
<xsl:apply-templates select="$result1"/>
I am trying to access a xsl template in a different xsl file from inside my template. The 2 templates are on different XSL files and that's the reason I need the document function. The templates also apply on different xml files.
My problem is how to call the second template from inside the first one. Sample of my code:
I am inside template Library:
<xsl:template match="Library">
<fo:table table-layout="fixed" width="160mm">
<fo:table-column column-width="80mm"/>
<fo:table-column column-width="80mm"/>
<fo:table-body>
<fo:table-row>
<xsl:for-each select="document(Library/#File)/Document/Books">
<xsl:apply-templates select="."/>
</xsl:for-each>
</fo:table-row>
<fo:table-body>
</fo:table>
</xsl:template>
and I am trying to access the template Books:
<xsl:template match="Books">
<fo:table-cell>
<fo:block font-family="arial" font-size="8pt" text-align="left">
<xsl:value-of select="substring(#IBAN,4)"/>
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block font-family="arial" font-size="8pt" text-align="left">
<xsl:value-of select="#date"/>
</fo:block>
</fo:table-cell>
</xsl:template>
The first argument inside the document function does not seem to be set correctly. Any thoughts on how should i rewrite it ? I couldn't find any issue in the forum having a similar problem.
Any help would be appreciated, thanks
To bring a template in from another XSLT file, use xsl:import or xsl:include. Use xsl:document when you want to apply XSLT templates to the XML found in the specified document in addition to the default input XML.
Unfortunately, you will not be able to use a variable in the path to the XSLT file because the path is resolved at compile-time.
If the path cannot be determined statically (possibly achieving the needed variation via a relative path specification), you might want to reconsider your overall organization. You could go so far as to compose your XSLT programatically before running it so as to be able to dynamically write the static #href, but do reconsider your overall solution architecture before going that far.
I am converting a docbook to an html using 1.77 xsl transformation. But when it is transformed it automatically generates a Table of Contents. How do you change this behavior?
I have found this: Disable table of contents for documents
So I am guessing that html xsl transform would be the presentation system?
Elaborate DocBook formatting is meant to be customized using an xsl stylesheet.

How to Use customize_formatting.xsl
Point your tools to use customize_formatting.xsl instead of the off-the-shelf docbook.xsl. Then, put all your formatting customizations in the body of the <xsl:stylesheet> section.
For TOC suppression, you can just uncomment the appropriate line.
There is a quirk with some (or maybe all) XSL 1.0 tools that seem to prevent them from handling the whitespace-separated pairs used in the body of <xsl:param name="generate.toc">. I have had success suppressing TOC by just using the single word article or book instead of the proper whitespace separated pairs.
When transforming, you can use the Transformer#setParameter(String, Object) method to specify no TOC generation like this:
transformer.setParameter("generate.toc", "nop");
