My appologies for not being clarify my intention earlier. I am
trying to identify a element in the DOM using XPath and replace
it with new element.
I have realized that how dumb I am that I could get help a lot
sooner and make everyone's life easier as well.
Your "detach" suggestion will work for what I need. Then how
can I add a new element at the same location where we detach
the old element, i.e., kinda replacing an old element with a
new element. Thank you.
Regards,
Pae
