[jdom-interest] Parsing an XML Schema

[Michael Kay]

No, you need to do a lot more than parsing the schema. 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.

I just need to parse the schema (dtd or xml schema corresponding) as a tree
structure, it means starting from the root, and then the children (prefix
parcours).

True, the XML Schema never declares a root element for its instances (valid
xml files), but there is one for the schema itself (the <schema> tag).
Seeing your answer, I can't hold myself to ask you this : Are you trying to
parse your XML Schema file (.xsd) ? or your XML files valid against your
schema (.xml or anything else) ?

The problem is that a schema does 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 ?
