  libxml2 has API to dump subtrees like the following. Use them !
    http://xmlsoft.org/html/libxml-tree.html#xmlElemDump
elements being parsed are generated within a document, always.
I don't know how you do the parsing but the leanest solution would be to
use the reader interface and its expand function.
