First, what is this?:
node()[(../. = /) and not(self::cmn:Comments)]
../. means the same as .., so you are trying to match any node whose parent
has a string-value that is the same as the string-value of the root node.
Getting the string-value of the root node is a pretty expensive operation,
it involves scanning the whole document. I suspect you are trying to match
the element whose parent is the root node, in which case you can write
match="/*". And the not(self::xxx) part is much better handled by defining a
second template rule with higher priority that has match="cmn:Comments".
Secondly, in the JAXP code you are frequently using Windows filenames in
places where URIs are expected. Xalan may let you get away with this (I
don't know) but Saxon certainly won't.
Thirdly, this expression: [name()=name(current())] is pretty fragile in an
environment with so many namespaces, because you are comparing prefixes, not
URIs. Test whether the namespace-uri and local-name are both equal.
Fourthly, you don't need xalan-nodeset(). The input is already a node-set,
you don't need to convert it.
Finally, for debugging try simply doing <xsl:copy-of> on the supplied
parameter in your match="/" template. Displaying the result of your complex
path expression simply proves that your path expression is wrong.

Subject: [xsl] Namespaces, params and Xalan
Hi,
I'm a bit stumped by this - I'm using Xalan and trying to pass an xml
fragment into my xsl as a parameter and then merge the
fragment with my
instance document.
What seems to happen is that the namespaces get stripped and I can't
query the XML fragment once it's passed in as a param e.g
xalan:nodeset($override)/cmn:MinorVersion/cmn:Number won't return
anything from the fragment because the fully qualified name
in the xpath
query isn't in the fragment (I can however use local-name() to return
something but that's a bit of a hack).
I saw something recently from Jenni Tennison that suggested that -
transformer.setParameter("TEXT", node);
effectively passes the node as a string and that this could
cause problems?
Or is it just something stupid I'm missing?
I'm also looking at trying to get saxon to do the same thing
with some
problems.
Any help would be most welcome.
My fragment looks like this -
<?xml version="1.0" encoding="UTF-8"?>
