How to replace text between two XML tags using jQuery or JavaScript?

I have a XML mark-up/code like the following. I want to replace the text inside one of the tags (in this case ...) using JavaScript or jQuery.

A new beginning Stuff here...

The source is inside a textarea. I have the following code, but it is obviously not doing what I want.

code=$("xml-code").val(); // content of XML sourcenewBegin = "The same old beginning"; // new text inside tagsnewBegin = ""+newBegin +""; code=code.replace("",newBegin); // replace content

This is just appending to the existing text inside the begin tags. I have a feeling this can be done only using Regex, but unfortunately I have no idea how to do it.
