Accessing CDATA section in XML DOM from Javascript

I'm trying to access CDATA inside XML file, works fine in FF but not IE (pretty much all versions). If anyone has any suggestions, please help.
Thanks in advance.

title=(x[i].childNodes[3].textContent);
Noticed you've hardcoded the 3. Are you trying to get the entire text node, <p> tags and all?

I'm not great with browser versions, but this might work.
title=(x[i].getElementsByTagName("p")[0].nodeValue);

Good call, Thank you! I actually did figured it out about 30 mins ago. Apparently in FF it's title=(x[i].childNodes[3].data and in IE it's title=(x[i].childNodes[1].data. Technically, all I need to do is create and if/else statement for each browser. Your solution would make it much more simple though, I will try it. Thanks again.

IE doesn’t count whitespace textnodes (i.e. linebreaks between elements). you could also loop through all childNodes, until you find a CDATA section:

Expand|Select|Wrap|Line Numbers

 for (i = x[j].childNodes.length; i--;) {

    if (x[j].childNodes[i] instanceof CDATA) {

        // this is your CDATA node

    }

}

@jkmyoung: I doubt getElementsByTagName() works inside CDATA nodes, since that is unparsed text.

from the XML point-of-view it would make more sense to use namespaces to save the HTML, though I don’t know how good IE is in handling that.
