[xsl] Parameter substitution

[Curtis Burisch <burisch@xxxxxxxxxxx>]

Hi,

I was going to start this message with something other than the 
ubiquitous "Hi I'm a newbie and I can't figure out how to do xyz can 
somebody PLEEZ help me" but alas I have failed in that, so let's cut to 
the chase:

Below is given a fragment from an XML document. Of note are the 
contents of the <ErrorText> nodes; the first one has a value of "%1 %2 
is not a valid date format.".

My task, (you guessed it) is to replace each %1, %2 etc.. with a string 
built from the correspondong ErrorParameter (formatted nicely of course)
. Being relatively new to XSLT, I can't think of a way to accomplish 
this in a generic manner. Has anyone got any ideas? I can't think of an 
approach that will actually work!

Thanks,
Curtis.
