Updating XML Data - what's the best way?

[JLJ2004]

Hi,
I have an XML file that contains certain data (see further down) which I want to update frequently. I am hoping that advise what the best technique for updating the data is (ideally by using a form), and maybe point me in the direction of some examples.

Thanks!

<?xml version="1.0" ?>
<?xml-stylesheet Type='Text/xsl' Href='Analyst.xsl'?>

This technique is extremely useful if you are inserting data. It's not quite as powerful if you have to do updates.
