How to convert javascript to ast xml?

Question

I am creating an XML JavaScript serializer Abstract syntax trees with ANTLR. The generator is quite complete, but I would like to know if there are any agreements on some problems, such as:

• like angle brackets in strings or regular expressions?
• how to translate if-then-else (for example, will there be an else node inside an if or not)?

More generally: is there such a translator? Is there an existing XSD for this XML based language?

EDIT

I am currently interested in free tools.

Parsers that generate code from XML and generate XML from code are easily accessible:

• PMD Custom Rules - O'Reilly Media

• estools / esvalid: confirm that the SpiderMonkey AST format is an ECMAScript program

• jantimon / handlebars-to-ecmascript: convert descriptors to AST attribute

• estools / estemplate: Valid (AST-based) JavaScript code that supports source maps.

• estools / esrecurse: AST recursive visitor

• estools / estraverse: ECMAScript JS AST bypass features

• estools / escope: Escope: ECMAScript area analyzer

• estools / esquery: ECMAScript AST query library.

You ask: "is there such a translator?". If the question arises: "does this exist in ANTLR?" then I suspect you will find the answer on ANTLR.org. My company has such a translator with all the resolved problems; if you want to see sample output as an answer here, I will prepare it specifically for JavaScript.

Here's a link to XML output for Java: What will AST (abstract syntax tree) look like for an object-oriented programming language?
