Parsing XML in JSFL?

Question

It seems that there is no xml parsing tool in available JSFL (Adobe Flash-extension Javascript script file) : http://osflash.org/pipermail/flashextensibility%5Fosflash.org/2006-July/000014.html

So, is there an easy and cross-platform way to add a javascript xml parser?

Answer 1

function parseXML (xml) {
    try { // normal browsers
     return (new DOMParser()).parseFromString(xml, "application/xml");
    }
    catch (e) { // IE
     var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
     xmlDoc.async = "false";
     xmlDoc.loadXML(xml);
     return xmlDoc;
    }
}

Answer 2

If JSFL uses ActionScript at some point, you can just do XML(xml_string) or XMLList(multiple_xml_nodes_string) as long as it's ActionScript 3.0 or higher. ActionScript 3.0 supports E4X witch is native XML in ECMAScript.

Answer 3

Well, you can use XML and E4X straight from JSFL using Flash CS3 or newer as the Javascript engine got upgraded to 1.6

Here's a quick snippet that loops through elements in the current selection and traces xml:

var doc = fl.getDocumentDOM();//get the current document ref.
var selection = doc.selection;//get the selection
var layout = <layout />;//create the root node for our xml
var elementsNum = selection.length;//store this for counting*
for(var i = 0 ; i < elementsNum ; i++){
   layout.appendChild(<element />);//add an element node
   layout.element[i].@name = selection[i].name;//setup attributes
   layout.element[i].@x = selection[i].x;
   layout.element[i].@y = selection[i].y;
}
fl.trace(layout);
