them give you an API to access the compiled schema. Saxon does, and Xerces does.
(As I think I mentioned about 30 messages ago). But we're way off topic for a
JDOM list by now.</FONT></SPAN></DIV>

You already hint at this when you talk about "starting from the root": you
don't mean the XML root here, you mean some kind of semantic root. (You're
wrong to imagine that a schema is structured as a tree. It's a graph, and
quite a complex one.) To do what you are attempting, you need to do much more
than parse the schema, you need to analyze the information in it. Since
that analysis is complex, and since there are off-the-shelf schema
processors that do it for you, I would suggest that you use them rather than
trying to write your own.</FONT></SPAN></DIV>

the XML Schema never declares a root element for its instances (valid xml
files), but there is one for the schema itself (the <schema>

trying to parse your XML Schema file (.xsd) ? or your XML files valid

not define a "root" element , and that's the main point for me, because I
need to work on the file (xml schema or dtd) as a tree structure, it means
the parsing must start by the root element and then the chidren of the
current element (from left to right -> prefix). So how can I do that ?
