I've got a few places where I have an attribute of type IDREFS and a
sequence of ID values like references="Location Party Organization".
I had thought a simple for-each loop would pull these apart with the
id() function, in something like this:
<xsl:for-each select="id(@references)">
<xsl:value-of select="."/>
</xsl:for-each>
Close ....
But it doesn't work. What I get is the content of @references with the above.
Really? I would have thought you'd get the concatenation of the
element content of the referenced elements.
The only other solution I have thought about is creating a template
and recursively pulling apart the string. This should work, but I
would think there is a simpler way to make this work. Is there a
solution I missed?
*If* you have properly declared the id attributes, for my example
they are called id=, something along the lines of:
<!ATTLIST foo id ID #IMPLIED>
then you should be able to say:
<xsl:for-each select="id(@references)/@id">
<xsl:if test="position()>1"> </xsl:if>
<xsl:value-of select="."/>
</xsl:for-each>
and it would report a space-separated list of unique token values
(rather than just @references since that might have duplicates).
If you don't have a declaration of the attribute type, then id() has
nothing to look up and will always return an empty node set.
I hope this helps, Dan.
