You need to do two things: (a) change the namespace nodes to use a different
prefix, and (b) change the QName-valued attributes to use a different
prefix.
For (a):
<xsl:template match="*">
<xsl:element name="{local-name()}" namespace="{namespace-uri()}">
<xsl:for-each select="namespace::*">
<xsl:namespace name="{if (local-name() = 'oldprefix') then
'newprefix' else local-name()}"
select="string(.)"/>
</
</
<xsl:apply-templates select="@*, node()"/>
</
</
For (b)
<xsl:template match="attribute(*, xs:QName)">
<xsl:attribute name="{name()}" select="concat(if (get-prefix-from-QName(.)
= 'oldprefix' then 'newprefix' else get-prefix-from-QName(.), ':',
get-local-name-from-QName(.))"/>
That's assuming a schema-aware transformation (using the schema-for-schemas)
so you can detect the QName-valued attributes by type. The alternative is to
match them all explicitly by name.
Not tested (and probably has bugs) but I hope it suggests a way forward.

Subject: [xsl] How to change namespace prefixes in a import
file hierarchy? Or at least append som pattern?
How to append a pattern to a namespace prefix? How to change
a namespace prefix in a import file hierarchy?
Assume there is a directory (tree) of XSD schema files which
start with ONE single "root" XSD schema file "root.xsd" and
which in turn imports other, related XSD schema files.
Regarding the used, embedded namespaces and their prefix it
looks like similar to:
root.xsd:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:mypref1="http://www.somedomain.com/foo/bar/";
...
xmlns:other22="http://www.somedomain.com/blah/";
....>
<xsd:import namespace="http://www.somedomain.com/foo/bar/";
schemaLocation="myfoobar/subschema1.xsd"/>
....
<xsd:import namespace="http://www.somedomain.com/blah/";
schemaLocation="myblah/subschema22.xsd"/>
<xsd:element name="..." type="mypref1:myelement111Type"/>
<xsd:element name="..." type="other22:myelement222Type"/>
...
Keep in mind that this is a simplified sample. In real life I
could have a system of dozends of imports, hundreds of
namespace prefixes and thousands of elements.
Now I want to change all prefixes "mypref1" to "newpre7". I
could this manually but due to the amount of occurencies and
the necessary changes this is not feasible.
Furthermore I dont want to use an text editor replace
function because this could be ambigious and not much simpler.
I would like to use a XLST script which would do the job for
me (after changing just a "from" and a "to" pattern inside
this XSLT script.
Is this possible somehow?
All the prefix occurencies should be changed in the prefix
definition and the usage places (e.g. <xsd:element>) in all
files of the import hierarchy.
How can I do this?
If a pure change is not possible: Can I at least append some
postfix to a prefix (e.g. add
from: mypref1
to: mypref1new
Thank you
Ben
