    capturing/changing child node

    this isn't working, but i'm not understanding why...i want to change the contents of the <span> within the <p> tag...all i have to work with is the <p> tag's ID.

    Code:
    document.getElementById('testid').childNodes[0].innerHTML='working!';
    and here's the html...

    Code:
    <p id="testid">this is <span>not working.</span></p>
    any hints?

    The span isn't the first child node. It's the second.

    really? ok, now i'm confused...isn't it supposed to be in relation to the <p> and by being within the <p> it's a child of it correct? Sorry, guess it needs to be dumbed down for me

    Yes, the <span> is a child of the <p>. The childNodes[] collection includes more than just element nodes. It also includes text and comment (<!-- ... -->) nodes, for example, if any are present.

    You could use this instead of childNodes[]
    Code:
    document.getElementById('testid').getElementsByTagName('span')[0]
