I'm a little late to this party but you can find the length of an XML object and have it return a value higher than one.

You will have to add ".*.length()" to your XML object name.

eg:

**************************
var $tkrData:XML;
$tkrData = XML(loader.data);

trace("number of child nodes = "+$tkrData.*.length());
**************************

in my case this returns 13.

i've been stuck 2 hours pulling my hair without understanding why i couldn't get the lenght of my xmlList. And obviously as it happens sometimes, reading and reading the guide over and over didn't help me notice those fu***ng parenthesis... ( it's LENGTH !! why the hell it's not working... 'coz it's LENGTH() doh!! )

I would suspect that it has something to do with the way the data is being returned. I would wager that is has something to do with how the XML class is implemented; using return methods for data access rather than directly letting you access the property values. This way, should something need to be changed internally in the future, previous code/documentation should still be valid (assuming the entire format does not have to be changed). Just my $0.02.

Totally agree. No matter the reason it´s sort of silly and not intuitive. If they needed to mark the diference they could have made it "nodesLength" or something. Having the same name just causes confusion. I wonder how many hours overall have been lost due to this.

Make sure you have an xmlList object instead of xml object to use the length property. Otherwise you always have 1 returned.

Thanks for that post. I agree. This post as really helped me. I had been stuck the last 4 hours because i couldn't display the length. Now everything works fine.

myXML.length() doesn't yield the same as myArray.length. No matter how many child nodes are in your XML object, the length property will be returned as 1.

I wondered the same thing when I noticed that. My guess was that it used a method because "length" could be a child node of the xml. Since parent.child is valid E4X syntax, it wouldn't really know if you wanted "length" as in a reference to the child node(s) or "length" as in the number of child nodes.
