Re: [xsl] {} quantifiers in regex

The regex attribute is an attribute value template, so curly braces
must be doubled:
<xsl:analyze-string select="$this-duration"
regex="((\d{{2}}):)?(\d{{2}}):\d{{2}}">

Hi all,

I have this XML
<?xml version="1.0" encoding="UTF-8"?>
<test>43:12</test>

and this non working XSLT
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="2.0">
<xsl:template match="test">
     <xsl:variable name="this-duration" select="."/>
     <xsl:analyze-string select="$this-duration"
regex="((\d{2}):)?(\d{2}):\d{2}">
         <xsl:matching-substring>
             <xsl:value-of select="regex-group(3)"></xsl:value-of>
         </xsl:matching-substring>
       </xsl:analyze-string>
</xsl:template>
</xsl:stylesheet>

If I change it to this
(removing \d{2} in favour of \d\d)

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="2.0">
<xsl:template match="test">
     <xsl:variable name="this-duration" select="."/>
     <xsl:analyze-string select="$this-duration" 
regex="((\d\d):)?(\d\d):\d\d">
         <xsl:matching-substring>
             <xsl:value-of select="regex-group(3)"></xsl:value-of>
         </xsl:matching-substring>
       </xsl:analyze-string>
</xsl:template>
</xsl:stylesheet>

it works

Am I overlooking something?
I am using Saxon 9B in Oxygen,
I had the same issue with older versions, but failed to report it

thanks

Geert
