Re: [xsl] WG: key multiple select

[David Carlisle <davidc@xxxxxxxxx>]

Firstly you should remove all uses of

disable-output-escaping="yes"

which almost always indicate a design error in the stylesheet.
If using XSLt you should aim to generate a tree of element nodes, not
the text markup of an XML document tagging.

You haven't really given a description of teh problem that you are
trying to solve, however
in

<xsl:variable name="pageid" select="$dfile[key('pageid', concat(id, '+',
$catid))]"/>


The current node after $dfile[ is the root node (/) of the document
referenced by $datafile) so the first id used in your concat(id  will be
the empty string unless id is the top level element of $datafile, and
will be the whole string content of $datafile if its top level element
is id. I doubt this is what you intended, but can't suggest a fix given
teh available information.

Similarly

<xsl:key
name="pageid" match="siteinfo/pages/page/id" use="concat(id, '+',
category)"/>

here the current node for the use expression is the matched id node, so
the id and category expressions used in the concat are selecting
children of this id element. Do you id elements really have child
elements called id?


<id>
	  	<![CDATA[1]]
	  </id>

That is not well formed, it should have ]]> not just ]], I will assume
that that was just a cut and paste error and your real input is well
formed.


If your input looks like this you almost certainly want to use
normalize-space function when generating the keys and looking them up
with key() the string value of that id element is

is

newline tab space space tab 1 newline tab space space

and so if you just use the string value of id to generate the key you
will have to generate exactly the same string when searching for teh
node with key() Perhaps though your real input doesn't have the
indentation?


The CDATA section of course isn't doing anything, that only affects teh
interpretation of < and & so  your input is equivalent to

<id>
	  	1
	  </id>
