Parsing C++ into XML representation

Code2Code.net: XML Parser web service

What the web service do?

This web service parses C++ code (passed in as a string), and returns a code DOM object (e.g. function containing statements, statements in turn contain expressions). The web service will produce very bad results for template classes and template functions.

What does the XML output look like?

The output is a <CompileRun> object.
Nested inside that are top level objects, e.g.

Class
Enum
Struct
Union
Namespace
VariableDecl
TypeDef
FunctionDecl
Function
Define

Inside a function, you have statements.
Inside a statement, there are expressions.

Perhaps the best way to understand is to examime a sample XML document:

For more specific questions, consider downloading the sample code and examining source code of the 'c_DOM' project.

URL of the web service

The URL of the web service is http://code2code.net/WebService.asmx
The corresponding WSDL file is here.
