xml and Env Vars

[Joshua Sparks]

I have an XML source that I want to modify to use Unix Environment variables to represent directories instead of hard coding them. I'd like to know if this is possible...knowing that XML is platform independant.

Thanks

The answer is - it depends.

One way would be to pass the environment variables in to your processor via command line parameters/arguments. Another way would be to roll your own document processor using something like libxml or libxslt (www.libxml.org) that would have have specific knowledge of which elements/attributes are actually enviromental variables and use getenv to retrieve the value.
