Well if you have an XML file in the file system then surely to read out
a value some parser has to read through the file until the value is
found. So while you don't need to build an XML DOM document of the whole
XML file if all you want is one value you need to read through the file,
you could do it with SAX parsing (Java, MSXML with VB for instance) or
with XmlTextReader parsing (.NET).
So decide on the tools (MSXML or DOM) that you want or can use, then
give some more details on how the key looks, how the desired output
looks and probably someone here can help you further.

MSXML can do DOM or (at least with VB or C++) SAX too, as said, DOM is
overhead if you only want to read out one value.
But it is you who has to decide whether he can or wants to use VB or
C++, documentation for SAX with MSXML is here:
