I am trying to apply XSLT on SVN log, I need to extract bug numbers from the commit messages. I am applying this regex on msg but get nothing back. What am I missing in XSLT? Thank you in advance Below is XML that I get from SVN:
<?xml version="1.0" encoding="UTF-8"?>
<log>
<logentry revision="265">
<author>dre</author>
<date>2015-04-13T02:35:25.246150Z</date>
<msg>modified code</msg>
</logentry>
<logentry revision="73283">
<author>john</author>
<date>2015-04-13T14:10:20.987159Z</date>
<msg>fixed bug DESK-1868</msg>
</logentry>
<logentry revision="73290">
<author>ron</author>
<date>2015-04-13T14:24:57.475711Z</date>
<msg>WEBAPP-1868 Fix for pallete list and settings dialog Selected Tab Index</msg>
</logentry>
</log><?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>SVN Issues</h2>

<td><xsl:value-of select="author"/></td>
<td><xsl:value-of select="date"/></td>

</xsl:matching-substring>
</xsl:analyze-string>

Note: Because the regex attribute is an attribute value template, curly brackets within the regular expression must be doubled. For example, to match a sequence of one to five characters, write
regex=".{{1,5}}". For regular expressions containing many curly brackets it may be more convenient to use a notation such asregex="{'[0-9]{1,5}[a-z]{3}[0-9]{1,2}'}", or to use a variable.
You do not want to anchor your expression to the end of the line using $ at the end of your expression. Otherwise the regex will only match when the message ends with an issue ID.
Use this regex expression to capture the entire bug number:
regex="((DESK|TRS|PEK|WEBAPP)-\d{{4}})"
