Another wrinkle... :)
I just noticed that in the same xml document I have an attribute like this:
<box:base-file-name>C:/test10/user/server/logs/server.log</box:base-file-name>
and one like this:
<box:stdout>C:\test10\user\server\logs\server.log</box:stdout>
with both forward and back slashes.
I need to change that c:\test10 directory whether it is c:\test10 or
c:/test10 and ideally make all the slashes in the value of the
elements be the same throughout the xml document. Is there a function
I can call to first convert the slashes to one unified format before
applying the substring?
Thanks,
Paul

Ken,
Thanks! I took your substring code and was able to use it
successfully. Thanks again!

I'd like it to look like this:
<box:base-file-name>C:/other103/user/server/logs/server.log</box:base-file-name>
I'm passing in an OLD parameter that contains "c:/test10" and a NEW
parameter that contains "c:/other103" but I'm not sure how to
substitute just the OLD portion for the NEW parameter in the value of
box:base-file-name without nuking the rest of the value which I want
to preserve.
Is it possible to just change a portion of the value?
Absolutely. Below I've given two answers, one using substrings (supported
in both XSLT 1.0 and 2.0) and one using replace() (supported only in XSLT
2.0) ... but I recommend that you use substrings and *not* replace() because
if the $old string has any regular expression pattern characters then you'll
get unexpected results.
Another problem with replace() is that it replaces all strings, not just the
first.
So, all things considered, just use substring-before() and
substring-after().
I hope this helps.
