I receive data from database like this :
description:<p>my name is ....</p>
I put this in a table, all I need is to put the text only, how can I remove the <p></p>?
You can explicitly replace the <p> and </p> tags only using the String.prototype.replace() JS string method, available as .replace(string, replacement) on any string in JavaScript. (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace)
const description = '<p>my name is ....</p>';
const newDescription = description.replace('<p>', '').replace('</p>','');
console.log(newDescription);
You can remove your html tags by using regex
const htmlRemoveRegex = /(<([^>]+)>)/gi;
const newString = description.replace(htmlRemoveRegex, '');

I have a string like this:
"noun<br> an expression of greeting <br>- every morning they exchanged polite hellos<br> <font color=dodgerblue> ••</font> Syn: hullo, hi, howdy, how-do-you-do<be>"
want to show it in a label as a rich text. for example Instead of <br> tags, text must go to the next line.
in Android we can do that with:
Html.fromHtml(myHtmlString)
but I don't know how to do it in libgdx.
I try to use Jsoup but it removes all tags and does not go to the next line for <br> tag for example.
Jsoup.parse(myHtmlString).text()
Jsoup.parse returns a document containing many elements -of- strings. Not a single string so you are only seeing the first bit. You can assemble the complete string yourself by going through the elements or try
Document doc = Jsoup.parse(yourHtmlInput);
String htmlString = doc.toString();
String htmlText = "<p>This is an <strong>Example</strong></p>";
//this will convert your HTML text into normal text
String normalText = Jsoup.parse(htmlText).text();
in kotlin i use this code:
var definition = "my html string"
definition = definition.replace("<br>", "\n")
definition = definition.replace("<[^>]*>".toRegex(), "")
Given a string containing 'blabla text blabla', I want to extract 'text' from it.
regexp doc suggests '<(\w+).*>.*</\1>' expression, but it extracts the whole <a> ... </a> thing.
Of course I can continue using strfind like this:
line = 'blabla text blabla';
atag = regexp(line,'<(\w+).*>.*</\1>','match', 'once');
from = strfind(atag, '>');
to = strfind(atag, '<');
text = atag((from(1)+1):(to(2)-1))
, but, can I use another expression to find text at once?
You can use the extractHTMLText function in Matlab, you can read about it in the following link.
Example that get the desired output:
line = 'blabla text blabla';
l = split(extractHTMLText(line), ' ');
l{2}
If you don't want to use a built in function you could use regex as Nick suggested.
line = 'blabla text blabla';
[atag,tok] = regexp(line,'<(\w+).*>(.*?)</\1>','match','tokens');
t = tok(1,1){1};
t{2}
and you'll get the desired output
You can simply use a Group.
Update of your pattern will be something like this:
<(\w+).*>(.*)<\/\1>
and this one include all tags:
<.*>(.*)<.*>

If you are using JQuery try this. No Regex required. But this might negatively impact performance if the DOM is hefty.
$jqueryobj = $(line);
var text = $jqueryobj.find("a").text();
I have following construct:
<h1>
<span>
</span>
</h1>
....
and
<div id="tourname">Riding trip arround the volcano</div>
Now the div with the id is filled by a php function and I would like that
my h1 looks like this:
<h1>
<span>Riding</span>
trip arround the volcano
</h1>
I managed to fill the h1 using this function:
$("h1").html($("#tourname").html());
but I have no idea how to split my string into 2 parts and fill one part
into that span and the rest behind the /span
Can you give a hint ?
Many thanks
You can do that in 2 ways .
1 - When you are writing using php , you can create the span for first word.
2 - Using jQuery. You can see the below code using jQuery
$(document).ready(function(){
var text = $("#tourname").html();
var firstword = text.substr(0,text.indexOf(' ')); // to get the first word
var remaining = text.substr(text.indexOf(' ')+1); // remianing words
var final = '<span>'+firstword+'</span> '+ remaining // combining by adding <span> around the first word
$("h1").html(final);
});
use this:
var strArr = $("#tourname").html().split(' ');
$("h1 span").html(strArr.shift());
$("h1").append(document.createTextNode(strArr.join(" ")));
This should be of some help.
Also consider this fiddle
This will be specific to your use only.
For more flexibility with number of text elements use strArr.splice(index, number_of_elements_to_include_in_span);
instead of strArr.shift();
I'm trying to find a regex for VBScript to remove some html tags and their content from a string.
The string is,
<H2>Title</H2><SPAN class=tiny>Some
text here</SPAN><LI>Some list
here</LI><SCRITP>Some script
here</SCRITP><P>Some text here</P>
Now, I'd like to EXCLUDE <SPAN class=tiny>Some text here</SPAN> and <SCRITP>Some script here</SCRITP>
Maybe someone has a simple solution for this, thanks.
This should do the trick in VBScript:
Dim myRegExp, ResultString
Set myRegExp = New RegExp
myRegExp.IgnoreCase = True
myRegExp.Global = True
myRegExp.Pattern = "<span class=tiny>[\s\S]*?</span>|<script>[\s\S]*?</script>"
ResultString = myRegExp.Replace(SubjectString, "")
SubjectString is the variable with your original HTML and ResultString receives the HTML with all occurrences of the two tags removed.
Note: I'm assuming scritp in your sample is a typo for script. If not, adjust my code sample accordingly.
You could do this a lot easier using css:
span.tiny {
display: none;
}
or using jQuery:
$("span.tiny").hide();
I think you want this
$(function(){
$('span.tiny').remove();
$('script').remove();
})
I am looking for a way to replace keywords within a html string with a variable. At the moment i am using the following example.
returnString = Replace(message, "[CustomerName]", customerName, CompareMethod.Text)
The above will work fine if the html block is spread fully across the keyword.
eg.
<b>[CustomerName]</b>
However if the formatting of the keyword is split throughout the word, the string is not found and thus not replaced.
e.g.
<b>[Customer</b>Name]
The formatting of the string is out of my control and isn't foolproof. With this in mind what is the best approach to find a keyword within a html string?
Try using Regex expression. Create your expressions here, I used this and it works well.
http://regex-test.com/validate/javascript/js_match
Use the text property instead of innerHTML if you're using javascript to access the content. That should remove all tags from the content, you give back a clean text representation of the customer's name.
For example, if the content looks like this:
<div id="name">
<b>[Customer</b>Name]
</div>
Then accessing it's text property gives:
var name = document.getElementById("name").text;
// sets name to "[CustomerName]" without the tags
which should be easy to process. Do a regex search now if you need to.
Edit: Since you're doing this processing on the server-side, process the XML recursively and collect the text element's of each node. Since I'm not big on VB.Net, here's some pseudocode:
getNodeText(node) {
text = ""
for each node.children as child {
if child.type == TextNode {
text += child.text
}
else {
text += getNodeText(child);
}
}
return text
}
myXml = xml.load(<html>);
print getNodeText(myXml);
And then replace or whatever there is to be done!
I have found what I believe is a solution to this issue. Well in my scenario it is working.
The html input has been tweaked to place each custom field or keyword within a div with a set id. I have looped through all of the elements within the html string using mshtml and have set the inner text to the correct value when a match is found.
e.g.
Function ReplaceDetails(ByVal message As String, ByVal customerName As String) As String
Dim returnString As String = String.Empty
Dim doc As IHTMLDocument2 = New HTMLDocument
doc.write(message)
doc.close()
For Each el As IHTMLElement In doc.body.all
If (el.id = "Date") Then
el.innerText = Now.ToShortDateString
End If
If (el.id = "CustomerName") Then
el.innerText = customerName
End If
Next
returnString = doc.body.innerHTML
return returnString
Thanks for all of the input. I'm glad to have a solution to the problem.
