Has to be said I've torn my hair out writing an XSLT that takes an input
document describing the configuration of a lot of machines, including the
IP address and netmask, and produce a document showing (amongst many,
many, other things) what networks there were with links to the machines on
each network. To do this, I had to mask the netmask with the IP address
to get the network address and then produce a table for each distinct
network address.
How did I do this?
With two XSLTs. One XPaths out the network config elements and outputs
CSV. Then some Perl munges this and outputs text-XML which is
entity-referenced into the original document (because we can't change the
input document on the fly, it always entity-refs this file, but the build
process starts by putting an empty file there so the first XSLT can work
without a parse error), whereupon the main XSLT finds the lists of which
machines should go in which tables nicely set up for it.
Boy did I wish I was doing that in something like PHP!
