How to read between xml tags?

[Anthony Liu]

Yes, Miki, your code works great to strip the XML tags
and return a clean text file.

But the thing is, I want to process the part between
tags each time it is read in.

For example if I have a tagged XML doc like so:

<tag1>Something here</tag1>
<tag2>something else here</tag2>

I want to get "Something here" in one read operation
and process it before I move on to get "Something else
here".

So any way to go about this?
