I have an element I want to copy and in the source it looks like this:
<a:elem
xmlns:a="example.com/ns/a"
xsi:type="nsc:foo"
xmlns:nsc="example.com/ns/sensitive"
xmlns:b="example.com/ns/b"
xmlns:c="example.com/ns/c"
...
xmlns:z="example.com/ns/z">info</a:elem>
What I want to achieve at the same time:
1) Keep the namespace declaration for the namespace sensitive content of
the xsi:type attribute (with prefix nsc).
2) Get rid of all namespace declarations that are not needed here (prefix
b, c, ..., z) and that clutter up my result document.
If I use copy-of with copy-namespaces set to 'no' the declaration for
namespace sensitive content will be lost. If I say 'yes' everything stays
the same. So is there a short way I have not seen yet or is the solution
some verbose template? :)
I don't think the template needed is very verbose at all since you
are limiting yourself to finding the one prefix that is found in the
xsi:type= attribute:
T:\ftemp>type heiko.xml
<?xml version="1.0" encoding="UTF-8"?>
<a:elem
xmlns:a="example.com/ns/a"
xsi:type="nsc:foo"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:nsc="example.com/ns/sensitive"
xmlns:b="example.com/ns/b"
xmlns:c="example.com/ns/c"
xmlns:z="example.com/ns/z">info</a:elem>
T:\ftemp>xslt2 heiko.xml heiko.xsl
<?xml version="1.0" encoding="UTF-8"?><a:elem
xmlns:a="example.com/ns/a" xmlns:nsc="example.com/ns/sensitive"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:type="nsc:foo"/>
T:\ftemp>type heiko.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
version="2.0">
<xsl:template match="*">
<xsl:copy copy-namespaces="no">
<xsl:for-each select="@xsi:type">
<xsl:copy-of
select="../namespace::*[name(.)=substring-before(current(),':')]"/>
<xsl:copy/>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
T:\ftemp>
I hope this helps. If there is no xsi:type attribute, then no copy
of the namespace node is done.

Thanks for help,
