Since I'm using Saxon for querying my xml documents, so I will see the xml schema processor that is provided in Saxon :
http://www.saxonica.com/documentation/schema-processing/intro.html

Is there an example in the source documentation that implements an xml schema as a tree structure ?

thanks for help.


Yes, every schema processor does this analysis. And some of 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.

Is there an XML Schema processor that makes this analysis ?

>>>>>>>
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) ?


2006/7/31, enis enis <enis_ch2001@yahoo.fr>:
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 ?
