[jdom-interest] Using variables in XML files

I would like to use variables in my XML files. For instance take the "value" 
attribute in the following element:

<foo name="projDir" value="${user.home}" />

My question is what is the best way to replace these "variables" and when? 

One solution would be to find and replace these variables while the XML file 
is being parsed (although I don't know how). 

Does anyone have any ideas on how to use variables in an XML file while 
keeping their use hidden from other code in a application?

Thanks,

I'm getting traversed by the parser next door,
She's traversed me seven times before.
And ev'ry time it was an N-ary (N-ary!)
Never wouldn't ever do a binary. (No sir!)
I'm 'er eighth tree that was N-ary.
