Are you sure of that? Are you sayng that the target, not the prefix,
is cheked by the processor?
But nevertheless i lied about my actual problem, (gee, i'm watching
too much "House") cause i was afraid that the moderator will come by
saying this is not a XSL question... But i'll risk it anyway...
My problem is that i'm using Sarissa to get some Schema nodes using
XPath, like this
var nodes = xmlSchema.selectNodes("//xs:element");
It seems that this is about the same situation you've pointed in your
answer, but that is not working, afaict it only works if the Schema
but not if it's
Anyhow i'm going to try this in a XSLT "per se", not in Sarissa, to
see if it works (the moderator...) and if it works i'll check with the
guys at Sarissa (if Manos don4t answer to this post first).
Thanks for your answer, it didn't solve my problem but it pointed me
to right direction, i think...

The prefix is a placeholder for the namespace. In your case, the
namespace is http://www.w3.org/2001/XMLSchema. It does not matter what
prefix is used in the XML document. To make sure XSL understands the
same namespace, all you have to do is put the following in your
This namespace can now be used in you XPaths. This works for both 1.0
and 2.0 XSLT. It does not matter what prefix you use. If, for instance,
the source XML looks like this (I assume you want to parse an XMLSchema
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" >
you can reference elements inside this schema like this:
<xsl:value-of select="//yourprefix:simpleType" />
to get all simpleType elements from the source. These will be visible
like "xs:simpleType" in the source document. If you want to remove the
prefixes to the output stream, you can expand the opening element of the
xslt as follows:
But this is not guaranteed to work always because of the "namespace
fixup process" at the end of the XSLT transformation.
