Convert XML to Regular Text Variable

I have an XML file I have parsed thru to extract particular values.

XMLParse(xf.carts.cart.header.shiptotal)

I am using the above tag to extract values, but this also extracts the XML code with the value. Although it displays on the screen as the value, in the html it has all the standard xml code as well.

The above looks like this in HTML:

<?xml version="1.0" encoding="UTF-8"?>
<ShipTotal>13.95</ShipTotal>

I need it to look like this:
13.95

All I need is the variable amount - is there a tag to extract only the value?

Thanks.
