Re: [xml-dev] Re: Inserting a text node before an element node useingthe

[Jan-Arve Sæther <jasaethe@trolltech.com>]

Hi, Spencer.

I am not sure what parentNodes does, but the cNode is really a sibling 
of the <em> element.
You can try this:
    var cNode = x.getElementsByTagName("em")[0].previousSibling;
    cNode.insertData(0, strText);

hope this helps,
Jan- Arve
