Just look at SXML:
http://www.pobox.com/~oleg/ftp/Scheme/SXML.html
It is an instance of XML Infoset as S-expressions which makes
XML<->SXML mapping very straightforward. 

XML is just another instance of XML Infoset, it even may be considered as
"... a verbose variant of Lisp S-expressions coupled with a poor man's BNF."
( P. Wadler. The Next 700 Markup Languages
http://cm.bell-labs.com/cm/cs/who/wadler/ )

XML has its advantages as widely accepted format for textual representation
of semistructured data, while S-expressions (and SXML in particular) is natural 
Scheme representation for such a data.

SSAX XML parsing framework (which includes XML->SXML parser and is available for
Guile), SXPath, SXML transformation, etc:

Best regards,
