Karl,
At 06:17 PM 3/31/2005, you wrote: Is it legal to create a key off of an xml source stored as a variable? So the key decleration might look like: This isn't legal, but not for the reason you think. In XSLT 1.0, a match pattern can't contain a variable reference. If not, is there a workaround? None is needed, really. If you declare the key normally <xsl:key name="myKey" match="data" use="some_element"/> and then be sure that when you call it, the context is inside $external_xml_source, you'll be fine: <xsl:variable name="var" select="[anything you need to capture context]"/>
<xsl:for-each select="$external_xml_source">
... inside here the key will retrieve nodes from $external_xml_source,
and $var still refers to whatever you need from outside it ...
</xsl:for-each>Your XSLT processor has enough information here to do the right thing -- and keys are specified to work this way. This is a FAQ. Cheers, Wendell
