E4X: List document namespaces?

How would开发者_如何学JAVA I get a list of namespaces in an XML document using E4X?

---

Use the namespaceDeclarations() method to get an array of namespaces:

var bar = new XML('<html:div xmlns:html="about:html"><p></p></html:div>');
bar.namespaceDeclarations().toString(); //about:html
