I'm trying to get the p tags out of this XML document. But I can't seem to figure out what I'm doing wrong. Help me out what am I missing?

I don't get an errors. But i don't see any output? It seems that it is just not finding the p tags.

Here is a snippet of my AS3 code:
private function xml_loaded( e:Event ):void {
var my_xml:XML;
my_xml = new XML( e.target.data );
my_xml.ignoreWhitespace = true;

var style_nodes // :XMLList;
var caption_nodes // :XMLList;

style_nodes = my_xml.child( "styling" );
caption_nodes = my_xml.tts.body.child( "p" );
// caption_nodes = my_xml.child( "p" );

for each ( var p in caption_nodes ) {
var _obj:Object = new Object();
var cap_text:String = p.toString();
var begin:String = p.attribute( "begin" ).toString();
var end:String = p.attribute( "end" ).toString();
trace( begin + ":" + ":" + end + " " + cap_text );
_obj.cap_text = cap_text;
}

Here's a snippet of the XML. There are no errors here I have used this file with different cod and works fine.

//find the number of p tags
var pTags= xml.tt[0].body[0].div[0].elements("p").length();
// loop through tags
for(var i=0; i<pTags; i++){
// parse data and attributes
var currentData = xml.tt[0].body[0].div[0].p[i];
var currentBegin = xml.tt[0].body[0].div[0].p[i].@begin;
var currentEnd = xml.tt[0].body[0].div[0].p[i].@end;
// do something to data here
// ADD CODE HERE
}

Thanks for the reply. But it's still not working.

When I trace the following I get undefined?

var my_xml:XML;
my_xml = new XML( e.target.data );
my_xml.ignoreWhitespace = true;
var pTags = my_xml.tt[0] // .body[0].div[0].elements( "p" ).length();
trace( pTags );

Seems if I trace the following I get 0. This should show 2.

var pTags = my_xml.child( "tt" ).length();

If I trace my_xml I get the text of my XML file?

trace( my_xml )

After banging my head on the keyboard for an hour or more I find that the following works:

var my_xml:XML;
my_xml = new XML( e.target.data );
// my_xml.ignoreWhitespace = true;

for each ( var p:XML in my_xml..p ) {
trace( p.@begin + " " + p.@end + " " + p );
}

If anyone can explain why the earlier do not work feel free to "school" me.

var ns:Namespace = xml.inScopeNamespaces()[0];
trace(xml..*::p.toXMLString());
trace('======================= '+ns+' =======================');
trace(xml..ns::p.toXMLString());
If you defined a namespace for a tag, than, you have to refer the tag by it's full name (QName) which consists of Namespace and localName.

you may need a listener to know when to access the XML. you are probably accessing it before it's fully loaded so it's blank. although your function is accepting an Event parameter so maybe you do have it?

xmlLoader.addEventListener(Event.COMPLETE, LoadXML);



function LoadXML(e:Event):void
{
xmlData = new XML(e.target.data);
trace(xmlData)

}

good luck dunno if i helped.

Oh, and BTW:
my_xml.ignoreWhitespace = true; will do absolutely nothing %)
ignoreWhitespace is a static property of XML class, so, if you want to use it, the syntax is as follows:
var xml:XML = <xml />;
XML.ignoreWhitespace = true;

Thanks for the replies. It appears the new system for working with XML in AS3 is very different from the AS2 version.

I had added ignoreWhiteSpace = true as this was useful in AS2.
