Sure,
Here is an example of the code:
function removeNode(tElement,tOrder){
if(pageRoot.getElementsByTagName(tElement).item(tOrder-1) !=3D
null) { =20
tNode =3D
pageRoot.getElementsByTagName(tElement).item(tOrder-1); // Get first
element by node name (i.e. section, fieldgroup, fields)=20
=09
tNode.getElementsByTagName('active').item(0).setNodeValue("No"); // Set
active element to "No"
try {
=09
alert(tNode.getElementsByTagName('active').item(0).getNodeValue()); //
Displays "No"
=09
alert(tNode.getElementsByTagName('active').item(0).getXML()); //
Displays <active>Yes</active>
=09
} catch(e) { // Catch any exception
if(e.code =3D=3D
DOMException.NO_MODIFICATION_ALLOWED_ERR) {
// display the error message=20
alert("XML Exception Error: Code
not remove " + tElement + ".");
} else {
alert("Unknown exception");
alert(e.code);=20
}
}
} else {
alert("Null object");
}=09
}
Thanks for your assistance.

Hi Eljon!
Can you whip up a quick recreation of the problem you're seeing please?
I'll take a look and see what's up...

I won't be able to look at this until tonight at the earliest, but I'll try to get to it as soon
as possible.
Can I ask a favor? Can you expand on this recreation a bit to include your source XML and
everything you need to recreate this - including the creation of the objects? That will make it
much easier for me to debug since I won't have to guess what your variables are or how the
function is supposed to interact with the objects. It's actually easier for me when I have a
slightly larger test case than the bare minimum. Sorry I wasn't clear about that originally...
If you don't have time, that's OK. I'll do my best.
One more favor :) Can you send the new|current recreation as a zipped up attachment to
djoham[at]yahoo[dot]com please? Yahoo mail mutilates code (and text attachments) to the point of
almost uselessness. It would be a big help if I was able to start with something that resembed
JavaScript code rather than Perl :)
Best regards,
David

Hi Eljon!
I think the problem is that you're setting the node Value on the element, rather than the text
node child of the element. You have
pageRoot.getElementsByTagName(tElement).item(tOrder-1).getElementsByTagName('active').item(0).setNodeValue("No");
which will set the node value of the <active> element, but not the text node under it.
I think what you want to do is this:
pageRoot.getElementsByTagName(tElement).item(tOrder-1).getElementsByTagName('active').item(0).getFirstChild().setNodeValue("No");
Note the addition of the getFirstChild() call. That will return the text node that you're actually
interested in.
Actually, on text nodes you're supposed to use setData rather than setNodeValue, but if you look
at the code, all xmljs does in a setData is call setNodeValue so it doesn't really matter from a
technical perspective...
The code above will set the node data/value (the visible text so to speak) of the text node
enclosed by the <active> node. When reading this value, you'll want to also make sure you're
reading from the text node to make sure you're actually getting the node value of the text object.
You can sometimes get away with not doing this, but it's not advised.
Please go ahead and give that a shot and let us know how it turns out....
