I proved some cases that could help you. I hope you undestand me.
1 - All the content of the pattern is read as an unique regular expresion. So
the only part to reference I know is {0}.
2 - BUT there are different situacion if you use:
case A: pattern="\.*(\d*$)" - Here {0} are all the numbers of the final
case B: pattern="month(\d*$)" - Here {0} is month + the numbers of the final.
I do not know exactly what you want to capture, but I undestand that could help
you.
3 - You could capture the case B and then for example via an xsl retrieve the
part you need.
Below are the examples:
<map:match type="regexp" pattern="month(\d*$)">
<map:generate src="documento.xml"/>
<map:transform src="documento.xsl">
<map:parameter name="valor" value="{0}"/>
</map:transform>
<map:serialize />
</map:match>
<map:match type="regexp" pattern="\.*(\d*$)">
<map:generate src="documento.xml"/>
<map:transform src="documento.xsl">
<map:parameter name="valor" value="{0}"/>
</map:transform>
<map:serialize />
</map:match>
File documento.xml
<?xml version="1.0" encoding="UTF-8"?>
<elemento></elemento>
File documento.xsl
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:param name="valor"/>
<xsl:template match="/">
<html>
<head>
<title>Expresión regular</title>
</head>
<body>
Captura de expresión regular:<br></br>
- aplication of a function to the value: <xsl:value-of
select="substring-after($valor,'month')"/><br></br>
- the value {0}:  <xsl:value-of select="$valor"/>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
I hope this help
I will prove if {1} have a value in some case.

Subject: Re: Regexp matcher with digits
Can someone kindly answer this question and give an example about how to
use regex and retrieve the matches. I am stuck with a project that's
writen in Cocoon and I need this to continue.
