variables - Loop on all var in xslt -

i have issue xslt syntax, stylesheet :

<?xml version="1.0" encoding="utf-8" ?> <xsl:stylesheet version="2.0"  xmlns:xsl="http://www.w3.org/1999/xsl/transform" xmlns:saxon="http://saxon.sf.net/"> <xsl:output method="xml" indent="yes"/>

select="format-number($avggetalarm,'0.00000')"/></avggetalarm> </testchargealarm> </xsl:template> 

what want create template <xsl:for-each select="allvariables"> , apply transform value of variables.

i dont know if possible, because haven't seen exemple online.

thanks helping

it's not clear me, why can't do:

<testchargecatalog>    <xsl:for-each-group select="testcase" group-by="@name">        <xsl:element name="avg{upper-case(                                 substring(                                    current-grouping-key(),                                    1,                                    1                                 )                              )                             }{substring(current-grouping-key(),2)}">          <xsl:value-of select="format-number(                                   avg(current-group()/@time),                                   '0.00000'                                )"/>         </xsl:element>      <xsl:for-each-group>   </testchargecatalog>
