RE: [xsl] Question about the key() function

[omprakash.v@xxxxxxxxxxxxx]

Hi,
    I get a "Out of memory" error when I run a transformation using the xml
and xsl given below using xalan.

Is this a xalan version issue. Iam using the xalan that gets shipped with
jaxp-1.3.

Also if I replace
<xsl:apply-templates select="key('x',addressbook/address/zip)" />

with
<xsl:copy-of select="key('x',addressbook/address/zip)" />

I get xml with root starting with addressbook though the key is supposed to
match only "address" nodes.
Also, I get an extra set of address nodes complete with child nodes with
duplicates outside addressbook but inside keyNode.

Can someone explain whats going on.

Cheers,
Omprakash.V

Because there is a bug in your XSLT processor. The correct output is:

Saxon 8.4 from Saxonica
...
<?xml version="1.0" encoding="UTF-8"?>
<keyNode>
   <Name>1, Frisby, 48392</Name>
   <Name>10, Backstayge, 02718</Name>
   <Name>2, Attired, 00218</Name>
   <Name>20, Backstayge, 02718</Name>
   <Name>300, McGoon, 27318</Name>
   <Name>31, Reckonwith, 02930</Name>
</keyNode>

The key() function is specified to remove duplicates, it appears your
implementation is not doing so.
