RE: [flexcoders] Re: How to extract data from XML

Ah, yes, cool, one more tool in my bag. I did know that text() returned
an XMLList (all expessions do), but never thought to try assigning text
to a specific element.  Thanks.

Technically, text() returns an XMLList where all of the objects are of
kind text.  And you can set the value of those individual nodes in
that list. So for example
text()[0] = value; 
should work.

OMFG the namespace was the problem. After I added that line I was able
to call 
Alert.show(myXML.logo.toXMLString()); 
and it worked like a charm. Thanks now I can finally start doing stuff
with my application. This snag has been holding me up for a few days.
One last thing, how would I go about extracting just what is between
the tags logo and /logo instead of the entire element and
attributes? Would I have to convert it to a single XML object first
like you said? Or is there some function that can do that? Thanks for
all your help Tracy, I'm starting to understand how XML works now
because of you.

[flexcoders] Re: How to extract data from XML

2008-05-22 Thread wild.katana 
Okay, first of all, thanks for all of your help, Tracy. 
I have checked the myXML variable with Alert.show(myXML) and it shows
what I pasted in the first post (that's where I got it). So I know
that myXML contains that. I tried doing
Alert.show(myXML.logo.toXMLString()) but it is still showing nothing.
I have read the documentation on using XML and tried many of the
things it says, but to no avail. One thing I don't wuite understand...
What is the difference between XML and XMLList? If the myXML.logo
returns an XMLList, then should I make a variable that contains it
first? Like 
var myXMLList:XMLList = myXML.logo;
Alert.show(myXMLList);
?
I will try that but let me know if that is what you were meaning or
not... Thanks again..

 First, did you trace or alert your XML in yur result handler?  If you
 did not and are assuming you know what your xml looks like exactly, do
 that now.
 
  
 
 Second, when attempting to view XML, always use toXMLString() (search
 the archives for why):
 
 Alert.show(myXML.logo.toXMLString())
 
  
 
 Third, when writing e4x expressions, unless you are very certain of
 yourself, it is best to do it one step at a time, using  temporary XML
 or XMLList variables as needed, and tracing the contained value using
 toXMLString().  Note that all e4x expressions(myXML.logo is one) return
 XMLList, not XML. The docs will show how to handle this.
 
  
 
 Fourth, review the XML class in the language Ref and the working with
 data cha[ter in the developers guide for an explanation on how to work
 with XML.  The link below is for Flex 2, but the XML stuff has not
 changed.

 Hello, I have loaded an XML from a URL using URLLoader. Now that I
 have it in an object, how do I access individual parts of that data?
 The XML looks like this:

 So let's say I wanted to access the information in the logo element,
 how would I do this? My code looks like this:
 
 public var myLoader:URLLoader; //declare this outside of a function.
 The leading underscore is just a convention
 public var myXML:XML; //this too
 
 private function initUrlLoader():void {
 
 var XML_URL:String
