But when I try to find an element whose id attribute is equal to the value of the 'from' variable, I get an error saying "Unexpected token [<function>] in path expression."
<xsl:variable name="from" select="@from"/> <xsl:variable name="docnode" select="document('../texts/odes.xml')"/> <xsl:message> <xsl:value-of select="$docnode//id($from)"/> </xsl:message>
You can't use id() this way. A slash '/' in an XPath mus be followed by another step, and functions, like id(), do not fall into this category (in XPath 1.0).
Use either a predicete <xsl:message> <xsl:value-of select="$docnode//*[@id=$from]"/> </xsl:message> (supposed all your ID attributes are named "id") or change the context using an xsl:for-each: <xsl:message> <xsl:for-each select="$docnode"> <xsl:value-of select="id($from)"/> </xsl:for-each> </xsl:message>
This makes it a bit inconvenient to use id() or key() to grab elements from another document, but so are the rules...
