I don't know what graph matching is, but what's wrong with:

1) Sort each anonymous node individually in form:

<#pred> <#obj> ;

2) Remove line breaks and surround each anonnode with "[ " and " ]."

3) Combine with regular triples and sort

You end up with something like:

<#subj> <#pred3> "aaa" .
[ <#pred1> "ob" ; <#pred2> <#obj> ; ].

Am I missing something?
