[CS3 JS] How to associate text with an XML tag

Question

Hello,
I have a script that allows one to create or modify an XML tag after one selects text, a text frame or an existing XML tag. It works fine for making the XML tag but it does not associate the text or text frame to the tag. To do that I have to right click on the selection and use the context menu to Tag Text or Tag Frame.
I want to make this automatic but cannot see how to script it.
Thanks for any help

I figured out the problem (which of course creates other interesting problems).
In the line:
var elementRef = rootElement.xmlElements.add (tagRef);
I forgot to add a reference to the xmlContent. It should read:
var elementRef = rootElement.xmlElements.add (tagRef, whatToTag);
However, this script is designed to create a dialog box where one can either create a tag along with attributes or edit an existing one. I'll post it when I am done, but there is one hangup. The script not only changes the name of a selected xml tag but all tags with the same name. How can I get it to change only the selected tag? Below is the boiled down script that duplicates that problem.
Thanks,
Tom
var myDoc = app.activeDocument;
var selObj = app.selection[0];
var TagIWantToChange = selObj.markupTag;
var newTagName = "PleaseWork"; //This line replaces all the coding to create a dialog box where the tag name could be edited.
TagIWantToChange.name = newTagName;
