[antlr-interest] antlr suitable for xml languages? (like bpel and are there existing grammaires)

[Dimitrios Kolovos]

Hi Dominik,

I would personally recommend going the SAX-DOM route. With libraries 
such as JDOM or dom4j you actually get the AST (in that case DOM) for 
free. Moreover, you can specify a W3C Schema or DTD to perform 
validation on your input. Finally, you can use XPath (e.g. Jaxen) to 
query your DOM.

Since the problem of parsing and managing XML documents has been solved 
in its general case - from stable and sophisticated libraries such as 
those mentioned above - I see no reason to re-implment the wheel and 
construct your own XML parser with ANTLR (espacially if you start 
thinking about escaping characters, different encodings etc).

Just my two pence,
Dimitrios
