[xsl] Removing white space from XML file

[Chad Chelius <cchelius@xxxxxxxxxxxxxxx>]

I am being supplied an XML file that contains white space in both the  
value of elements and also in the general structure of the XML file.  
Most often in the value of each element there are several spaces but  
sometimes there are other spaces as well. Is there an easy way to  
remove these? Also, within the value of each element, there needs to  
be one space instead of several. I know this can be accomplished with  
a find change in many programs, but it would be great if I could  
remove these extra spaces using an XSLT.
