Subject: [xsl] Populating keys with values from other documents From: "Ashton, Andrew" <andrew_ashton@xxxxxxxxx> Date: Tue, 29 Jun 2010 14:31:00 -0400 |
I am trying to look up a value in an XML document (people.xml) based on a @ref attribute in my primary document (source.xml). I know that the @ref values in source.xml will match the @xml:id values in people.xml. I can do something like this: <xsl:template match="name"> <xsl:variable name="uriRef"> <xsl:value-of select="(ancestor::*[@xml:id]/@xml:id)[last()]"/> </xsl:variable> <xsl:variable name="person" select="document('file:///people.xml')//person[@xml:id=concat($var, '')]"/> <xsl:if test="$person/residence/country"> <span about="ont:place#{$uriRef}" property="foaf:based_near" > <xsl:value-of select="$person/residence/country"/> </span> </xsl:if> </xsl:template> But this is incredibly slow for large documents. I have experimented with using xsl:key, but I haven't had much. Essentially I would like to pre-populate the key with the values from people.xml, but I can't quite figure out how to do that in a way that doesn't get me into a looping scenario and/or that allows me to pass my $uriRef value to the template that processes the key. Can anyone explain a better approach? Thanks, Andy
