Replace text in XML object using a sequence of tags as input

Question

Hi, I need to write an apparently very simple function that replaces a text between tags in an XML object receving as input the sequence of tags to identify the element, but I miss one point.
I travel through the XML tree using a element variable like
Code:
element = element.child(n)
using at each step the tags provided as input to decide the value of "n". Now, when I reach the tags that contain the text to be replaced, what to do? If I use
Code:
element.replace(0, newValue)
I replace the text just in element  not in the original object...
For example having
<publishing_date>
       <year>2002</year>
       <month>Jan</month>
<success_date>
       <year>2004</year>
       <month>Feb</month>
</success_date>
I want to call a function like
replace(["success_date", "month"], "Mar")
and have an XML object where the second occurence of Feb is replaced with "Mar"
Any suggestion on this easy task?
Thanks a lot
Giuse

Answer 1

Hi Michael, thanks but my question was difference.
I need to make a function to operate with input tags, not with known tags. So I am writing a loop that scans the XML object using the tags provided in input until it reaches the desired tag with the text to be replaced.
That's why I wrote
element = element.child(n)
that I was thinking to use at each step of the loop looking for desired tag.
There I have the problem: if I use
element.replace.... I am changing the text between the tags in the element variable, not in the original XMLObject, and since there are no pointers in JavaScript, how to do that?
I hope to have been more clear now..... did I ?
Thanks and best reagrds
