[xsl] xsl:for-each with atomic values and nested xsl:apply-templates

["Christian Roth" <roth@xxxxxxxxxxxxxx>]

Hi,

trying to figure out what the error with this fragment (XSLT 2) is:


<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">

  <xsl:template match="src">
    <xsl:for-each select="tokenize( 'a c', '[ ]')">
      <xsl:apply-templates select="/doc/*[current() eq string(@id)]" />
    </xsl:for-each>
  </xsl:template>
  
</xsl:stylesheet>


This gives an error, "Cannot select a node here: the context item is an
atomic value".

I see that the xsl:for-each iterates over a sequence of atomic values
(xs:string). So I assume that current() results in an xs:string, which
should be comparable to the string(@id) expression. The select="..."
expression does not depend on a context node, as it is an absolute path
from the document root. xsl:apply-templates results in a sequence and
therefore should be no problem in the xsl:for-each body. It's certainly
trivial - I just don't see it right now... :-/

An input for the above would e.g. be:


<doc>
    <src />
    <elem id="a">A</elem>
    <elem id="b">B</elem>
    <elem id="c">C</elem>
    <elem id="d">D</elem>
</doc>


The desired output would (probably...) be: 

AC
