    Nodes named <text> in E4X

    HI all,

    I must admit I'm not enjoying getting my head around E4X. The latest issue is I can't access any nodes in my tree which have the tag name "text":

    Code:
    <root>
        <section>
            <text>Hello</text>
        </section>
    </root>
    This doesn't work...

    code:
    root..text



    ...I'm guessing because ActionScript thinks I am trying to say "root..text()".

    This works...

    code:
    root.section['text']



    ...but it means I need to know the path first which defeats the purpose of E4X!

    Does anyone know a way round this, or do I need to change my tag names to something else?

    Cheers,
    Dave

    OK, I got it. Slightly convoluted, but I guess I'm still learning the power of this new syntax:

    code:
    var list:XMLList = xml..*.elements('text');

    Hi and welcome,

    As i understand it, E4X is a new extension to JavaScript that adds direct support for XML to JavaScript.
    (with limited browser support)

    a typical example is -

    Code:
    var x = new XML();
    
    x=
    <note>
    <from>Jani</from>
    <body>Don't forget me</body>
    </note>;
    For the example above, the JavaScript statement: document.write(x.from)
    will produce the output: Jani


    I posted the above before seeing your reply.
    Glad you're sorted

    Thanks for the welcome MD. Yup, I found some rather good links and am slowly getting my head round it!
