[xsl] serializing and parsing xml in xslt

[Erik Wilde <net.dret@xxxxxxxx>]

hello everybody.

i ran across a problem where someone wants to basically serialize and 
parse xml in xslt. the idea is to "package" some xml sub-trees in 
attribute values as strings (with escaped markup) and then in another 
transformation to re-use this text as xml. and all this in xslt 1.0...

i know that this is a weird idea, but i found it challenging to think 
about how this could be done. i thought that one would basically have to 
write one's own serializer and parser in xslt, which probably is rather 
expensive. am i missing some better way to solve this problem?

thanks and cheers,

dret.
