Michael
Thank you for confirming that it works in other xsl processors.
For the record I've submitted this as a xalan bug:

Your code works fine in Saxon. It reports:
Duplicate state name: standby
Duplicate state name: record
Duplicate state name: record
Duplicate state name: off
Duplicate state name: off
Duplicate state name: standby

Subject: [xsl] xsl:key containing mixed elements
Hi
I have a problem that I'm trying to solve using <xsl:key>
but I'm not
getting the results that I expected.
It's probably best to explain first what I want to do and
then show how I
tried to use <xsl:key> to solve the problem.
I have a file containing a mixture of <UML:SimpleState> and
<UML:CompositeState> elements. Each one has a name
attribute, but in
the case of the <UML:CompositeState> element the name comprises
of a state name
followed by a colon followed by a sub-machine state name.
What I want to do is simply read my file and report any
duplicate state
names.
So, here's a simplified example of some of the data in my file:
<UML:SimpleState name="on" />
<UML:SimpleState name="off" />
<UML:SimpleState name="off" />
<UML:SimpleState name="standby" />
<UML:CompositeState name="rewind:rewinding" /> <UML:CompositeState
name="forward:fastforwarding" /> <UML:CompositeState
name="standby:waiting" /> <UML:CompositeState
name="record:recording"
/> <UML:CompositeState name="record:recording" />
I'd like to generate error messages for states 'off',
'standby' and 'record'
because they are duplicates.
This is how I tried to solve the problem. It works for the
'off' case but
not for the 'standby' or the 'record' cases:
<!-- Create an index containing the name of all simple states
and the first part of the name of all composite states -->
<xsl:key
name="name"
match="UML:CompositeState[(_at_)name]"
use="substring-before(@name,':')" />
<xsl:key
name="name"
match="UML:SimpleState[(_at_)name]"
use="@name" />
<xsl:template match='/'>
<xsl:for-each select="//UML:CompositeState[(_at_)name]">
<xsl:variable name='name'
select="substring-before(@name,':')"/>
<xsl:if test="count(key('name',$name))>1">
<xsl:message>Duplicate state name: <xsl:value-of
select='$name'/></xsl:message>
</xsl:if>
</xsl:for-each>
<xsl:for-each select="//UML:SimpleState[(_at_)name]">
<xsl:variable name='name' select="@name"/>
<xsl:if test="count(key('name',$name))>1">
<xsl:message>Duplicate state name: <xsl:value-of
select='$name'/></xsl:message>
</xsl:if>
</xsl:for-each>
</xsl:template>
Can anyone enlighten me please?
BTW I'm using xalan:
