Re: [flexcoders] complex xml parsing

[Vadim Melnik]

Hi,

In addition to communication issues, there is problem with E4X syntax.
E.g. <msRun/> node in the attached XML snip is defaulted to 
http://sashimi.sourceforge.net/schema_revision/mzXML_2.0 namespace, and 
"snip[]" syntax
seems incorrect at all:

>>> Alert.show(xml.msRun[0].scan[]); <<<

var xml:XML = event.result as XML;
var ns_mzXML:Namespace = new 
Namespace("http://sashimi.sourceforge.net/schema_revision/mzXML_2.0";);
Alert.show(xml.ns_mzXML::msRun[0]);

Thanks,
Vadim.

Dear all,

Here is a fragment of xml. When I try to parse it like that :

import mx.rpc.http.HTTPService;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;

public function addMzXMLSpectrum(path:String):void{
var service:HTTPService = new HTTPService();
service.url = path;
service.resultFormat="e4x";
service.addEventListener(ResultEvent.RESULT, resultHandler);
service.send();
}

public function resultHandler(event:ResultEvent):void{
var xml:XML = event.result as XML;
Alert.show(xml.msRun[0].scan[]);
}

but I never obtain any result :-( Does someone has an idea why ?
