parsing xsd using xerces c++

[chaman bagga]

 
 
Hello Xerces Experts,
 
I have a requirement to traverse the tree structure of an XSD file, and then 
generate a tree like structure roughly corresponding to the hierarchy of the 
XSD structure.
 
I looked at SCMPrint.cpp in samples, but its not clear to me on how to do a 
tree traversal (depth first pre-order I believe) of the structure.
 
Any help / sample code is greatly appreciated.
 
Regards,
Chaman.
