Reset to default 3I know this is an old question, but I was looking for a solution to this problem as well (using Flash CS3). I needed to parse XML from a data file on disk. Combining the suggestion of George Profenza I was able to get it to work with using eval(). The key is to remove the first line (the xml declaration):
xmlData = eval( FLfile.read( xmlFile ).split( '\n' ).slice( 1 ).join( '\n' ) );
... and you're good to go!
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);
var xml = new XML(FLfile.read(file));
Then you can access all your nodes and attributes by writing this:
xml.nodeName
xml.nodeName.@attribute1
xml.nodeName.@attribute2
nodeName is the name of your node. attribute1 should be the name of your attribute.
I hope this helps.
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.
What works nicely for me is just creating a SwfWindow. Working in JSFL is nice and fast because you can change out the file without having to restart Flash, but often ActionScript gives you more power.
My current project does a couple tricks:
I will create objects in JSFL and then convert them to XML. I have to serialize them from Object format into a string which I pass to the SwfWindow (Panel). From the Panel, I take the String can convert it into XML. Then you can do anything you want in Actionscript 3.0.
If I just have XML manipulation, I will prompt the User for a XML files path in JSFL code, but hand the URL directly to the Panel, and have the Panel just load the XML directly.
Finally. For saving the XML, I will have to convert the XML to string via, 'xml.toXmlString()', but you also need to remove the '\n' so that you can hand the data to JSFL. I will strip out the '\n' for '|' or whatever you like. Then pass the string to JSFL, and you then can deserialize the string and change the '|' back to '\n' and save the file. Either using the older 'Save Output Panel' method, or using the newer File Write method.
Hope that helps.
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;
}
}
