Hmm, it actually might not be all that easy. The RegexpURIMatcher
uses the org.apache.regexp package.
Details about the syntax are at:
http://jakarta.apache.org/regexp/apidocs/org/apache/regexp/RE.html
and it seems like you can do negation, but only with character classes
(Unless I'm missing something painfully obvious)
I guess the brute force ugly way would be to subclass
AbstractRegexpMatcher to return true if the RE *doesn't* match, or
allow the matcher to take a parameter to tell it to use inverse logic
for determining a match.
I take that back. This works:
<map:match type="regexp" pattern="^bob$">
<map:generate src="bob.xml"/>
<map:serialize type="xml"/>
</map:match>
<map:match type="regexp" pattern="[^b][^o][^b]">
<map:generate src="notbob.xml"/>
<map:serialize type="xml"/>
</map:match>
HTH,

The problem with the above is it will only match 3 letter long urls (I
am pretty sure). Eg. 'ab' would not be matched by the second regex.
The regular expression I need to use is also much more complex then 'bob'
Knowing what regular expression library is a good thing to know. Thanks.
That should help me figure it out.
