XML into flash?!

[tobiasniva]

I´ve previously worked with variables loaded into flash by having a string returned to me when I load an asp-page (loadVariables), and then used that variable within flash. Now our "coders" have made a webservice that I send parameters into and then get a XML-aswer back...loaded into a movieclip in my movie.
How do I use this answer?! Below I have an example of it:

<?xml version="1.0" encoding="utf-8" ?>
<boolean xmlns="http://www.infracontrol.com/">false</boolean>

I want to use that "false" but I don´t know how to get it out of the string, ´cause it´s not a variable with a value in it?!

Please help me!
Can I use the XML-object to "extract" the answer sent to me? Or put it in a variable on "my side", within flash?!

Hi tobiasniva,

First off, when showing XML in these forums, wrap it in [php] and [/php] so that it shows up like this:

<boolean xmlns="http://www.infracontrol.com/">false</boolean> 

Next, you need to load your document into an XML object, like this:

code:

---

var xmlDoc = new XML();

xmlDoc.ignoreWhite = true;

xmlDoc.onLoad = parseXML;

// this will depend on how you access your Web Service

xmlDoc.load( '/WebService.asmx' );



function parseXML( success )

{

  if( success )

  {

    // XML loaded and parsed OK

    // now we can get the value...

    // this = the XML document

    // this.firstChild = your root element (<boolean />)

    // this.firstChild.firstChild = the text element

    // this.firstChild.firstChild.nodeValue = the text value of the text element

    trace( this.firstChild.firstChild.nodeValue );

    // of course, you would probably set a variable, eg:

    _root.blnTestResult = (this.firstChild.firstChild.nodeValue == 'true');

    // note that inside this function we have to use absolute paths

    // to variables etc, thus the _root. prefix

  }

  else

  {

    // XML failed to load

    _root.gotoAndPlay( 2 );

    // of course you should use a frame number that corresponds to 

    // a nice error display, or do something simmilar

  }

}

Hope this helps!

One more question though...

I see that you´ve used XML.load. I know that this checks if the XML is loaded correctly...but is it then necessary to use if (XML.loaded == true) { myFunction } to be sure that the whole XML is loaded!?! Or is this "overkill"?

Grateful for tips...

well no, another way of doing it would be:

 onload = parseXML; 

this will immediately call the parseXML function as soon as the data has been loaded. Its also a better way of doing things.
