[xsl] Re-insert IDs and RIDs

["J. S. Rawat" <jrawat@xxxxxxxxxxxxxx>]

Hi
Have anybody any idea about how to re-insert IDs and RIDs as shown in 
the following example by xslt 2.0.

Input
<doc>
<p> xxx <anchor rid="a5">key 1</anchor> ... <anchor rid="a8">key 
2</anchor> xxx <anchor rid="a5">key 1</anchor> ... <anchor 
rid="a8">key 2</anchor></p>
<keys>
<key id="a5">key 1</key>
<key id="a8">key 2</key>
</keys>
</doc>

REQUIRED OUTPUT
<doc>
<para> xxx <x rid="x1">key 1</x> ... <x rid="x2">key 2</x> xxx <x 
rid="x1">key 1</x> ... <x rid="x2">key 2</x></para>
<items>
<item id="x1">key 1</item>
<item id="x2">key 2</item>
</items>
</doc>
Thanks
