(The first post didn't seem to make it through for 3 days, so I'm reposting)

Does anyone know if future versions of XSLT will allow variables or
parameters in the "match" attribute of xsl:key?

In particular, I have a parameterized XSLT stylesheet (using xsl:param),
where the param is used to filter what is generated.  I'm using keys for
Muenchian style grouping.  I can generate keys for more than I want, and
filter later.  However, the input can be several MB., so I'd like to
restrict what keys are built for performance reasons.  When I hard code
equivalent filters on the key match (instead of using filters that reference
a variable), I do see enough of a performance difference to want to do this!



As a side note.  I sure wish there was an "ends-with" string function in
addition to the "starts-with" function.  I seem to need it much more often
than "starts-with".  I'm imitating "ends-with(source, find)" with

find = substring(source, 1 + string-length(source) - string-length(find))

But for input of several MB., it takes a bit of a hit that it wouldn't if
there was an 'ends-with' function! (yes, I timed the above with a comparable
"contains" and "starts-with" variant).  Does anyone have a faster way to
imitate "ends-with"?


Thanks!
