Let's do some assumptions first.

I'm assuming you have used DOM to get a Document with your XML data in it.

By "value" I assume yuu mean the text between the start end end tags, like
the "xxx" in this example:

<a>xxx</a>

To do that, you need to
1) Find the <a> element.
2) Delete all of its existing children.
3) Create a new Text node with the new content you want.
4) Add add it as a child to the <a> element.
5) Do anything else you want to do to the Document.
6) Serialize it to save the XML file.
