How to convert JavaScript code to a xml representation of the ast?

Question

I am building an XML serializer of JavaScript Abstract Syntax Trees with ANTLR. The generator is quite complete but I would like to know if there are any conventions about some issues such as:

how handle angle brackets in strings or regular expressions?
how to translate if-then-else (e.g. will the else node be inside the if one or not)?

More generally: does such a translator already exist? Is there any existing XSD for this XML-based language?

EDIT

I am currently interested in free tools only.

I don't understand "quite complete ... but how to handle if-then-else" in the same breath. If you have the AST, exporting an XML version of it is pretty trivial: walk the AST, spit out node and children descriptors. If you do that, your question about "how to handle if-then-else" vanishes, as you must have already solved it in building the AST. — Ira Baxter, Jul 21 '11 at 18:49
You ask, "does such a translator exist?". If the question is, "does this exist in ANTLR?" then I suspect you'll find the answer at the ANTLR.org site. My company has exactly such a translator with all the issues resolved; if you'd like to see an output sample as an answer here I'll produce one for you specifically for JavaScript.

"Quite complete" = the translator actually produces XML code from JavaScript but I would like to know some state-of-the-art similar work to make a comparison about its quality. The if-then-else issue was just an example and my question stressed about _conventions_: should I translate it in or in or in ... — Federico Bellucci, Jul 22 '11 at 08:43
"Conventions"? The simplest conventions are best. Produce XML that matches the shape of the AST you have. I'd expect an tag with 3 children. — Ira Baxter, Jul 22 '11 at 13:49

Parsers which perform code generation from XML and generate XML from code are readily available:
