You can use the XSLT current() function if you prefer this to using
variables. (Some people prefer variables). You can also make do with a
single variable:
<xsl:for-each select="document($cfgschema)/ConfigSchema/RootSection">
<xsl:variable name="x" select="." />
<xsl:variable name="SectTypeDef"
select="document($cfgschema)/ConfigSchema/SectionType[@Name=$x/@Type]"/>
or
<xsl:for-each select="document($cfgschema)/ConfigSchema/RootSection">
<xsl:variable name="SectTypeDef"
select="document($cfgschema)/ConfigSchema/SectionType[@Name=current()/@Type]
"/>
I would actually tend to write this as:
<xsl:for-each select="document($cfgschema)/ConfigSchema/RootSection">
<xsl:variable name="SectTypeDef"
select="../SectionType[@Name=current()/@Type]"/>
unless there are many SectionTypes, in which case I would use a key.
XSLT coding questions are probably better discussed over on xsl-list at
