This should do that:

In this example, I'm using groups and a quantifier, since the first match
gets repeated twice. You can expand that out if it's easier to scan.

Application level validation. It will be interesting to see how that works
out.

[tw5] Re: Test if a tiddler title is of a particular form
Mark,
This actually seems to work really well. I always like to return the favour
so perhaps you will find this interesting and its implications.
Place the following in a tiddler tagged $:/tags/ViewTemplate
\define myregexp() ^\w+?\.\w+?\.\w+?$
<$list filter="[titleis[missing]]" variable="missingTiddler"
>
<$list filter="[{!!title}regexp]">
Tiddler is missing and in w3w format
<$list filter="[title!is[missing]]" variable=
"missingTiddler">
<$list filter="[{!!title}regexp]">
Tiddler is in w3w format
Now if a tiddler has a title of the form word.word.word the above will
display according to if it exists or not.
Why is this so interesting?
If someone comes to my online wiki using a link such
as mywiki.html#test.w3w.example
they will open the tiddler mywiki.html#test.w3w.example if it exists
if it does not exist they will presented with the missing tiddler, which I
can code to have a button appear on it, to help the user create the tiddler.
This provides a way to guide a user into creating a tiddler that does not
exist by a title they provide, that meets a naming standard. It could be
firstname.surname
Regards
Tony

[tw5] Re: Test if a tiddler title is of a particular form
Mark,
Thanks, that will list all tiddlers with that title form (Exhaustive
testing remains)
And the following will reveal if the current tiddler has this form
\define myregexp() ^\w+?\.\w+?\.\w+?$
<$list filter="[is[current]regexp]">
Thanks
Heaps

Regexp is SOOO slippery.Without knowing more about your data, and your
exact requirements, it's hard to know if this nails it. But you can test
and tweak it and see what happens.
If you ever need to extract strings, then you will need something similar
to the solution in PR 2963.
