[xsl] Deleted selected nodes from XSD - howto for Newbie needed

---

---

Hello everyone

I want to delete some unwanted nodes in an XML schema file. Unluckily I'm
only able to copy the whole structure. Whenever I access a specified node to
copy, I get the the text content but not the structure of the node. I think
it is just the right select-expression, that I'm not able to find.

The nodes I want to preserve contain named and unnamed complex types &
simple types and references which should be still in the resulting XSD. The
not needed complex types and referenced elements that were part of the nodes
that are to be deleted shouldn't be in the resulting XSD. Imports, includes
and namespaces are not to be considered.

Above you'll find some example.

Kind regards & thanks in advance

"It never hurts to multiply by zero -- it simplifies things a lot." Richard

Simplified:

/Root/AllNodes/Header
/Root/AllNodes/Header/Detail
/Root/AllNodes/Nodes/NodeToBeKept1/..
/Root/AllNodes/Nodes/NodeToBeKept2/..
/Root/AllNodes/Nodes/NodeToBeDeleted1/..
/Root/AllNodes/Nodes/NodeToBeDeleted2/..

should result in

/Root/AllNodes/Header
/Root/AllNodes/Header/Detail
/Root/AllNodes/Nodes/NodeToBeKept1/..
/Root/AllNodes/Nodes/NodeToBeKept2/..


Here is the excerpt from my XSLT that doesn't work:
..
<xsl:template
match="/xs:schema/xs:complexType/xs:choice/xs:element/@name['NodeToBeKept1']">   <xsl:copy>
    <xsl:apply-templates select="*|@*" />
   </xsl:copy>
</xsl:template>
..

Here is the complete example schema
