Actually, one of the more interesting issues with this thread was acurately picking up all names from all levels, there is an annoying habit of <UL> tags messing up the pattern, also of the main post being marked up differently.

Anyway, Ill revisit this a bit later, :-)

Have you registered your Name Space?

Those whom the gods would destroy they first interest them in parsing natural language... really, in order to come up with a satisfactory solution to this, we're going to have to find a way to distinguish between the content of nodes... we need a script that can make an intelligent guess whether the node is a response or an etymology. This is a bit too rich for my blood, but I look forward to seeing it done :)

riight, but like I said, i'm deliberately matching only replies of depth 1, which all do conform (only 2nd level replies got the ul bug, and If i was parsing them, I'd just have the improper html in there regardless). I saw what you did ;D

Disclaimer: Don't blame. It came from inside the void
perl -e "$q=$_;map({chr unpack qq;H*;,$_}split(q;;,q*H*));print;$q/$q;"

Well, to be mildly critical there are two (or more depending on how you look at it) scenarios where we can/need to extract information from. Yours only matches one fixed version (yes i know it was deliberate decision :-) now for the record (and in rehersal for that tutorial you suggested :-) Ill list the others:

Note the buggy HTML? :-)

So what I did was look for the content of the FONT tag. If it matches a 'finger print' for one of the following two

<font size=2>
      # Optional part begins 
      <A HREF="/index.pl?node_id=121046&lastnode_id=110166">Re: Re: Re
+: Name Space</A>
      <BR>
      # Optional part ends
      ' by '
      <A HREF="/index.pl?node_id=103111&lastnode_id=110166">George_She
+rston</A>
      ' on Oct 24, 2001 at 01:21'
</font>
[download]

Then I do a few more checks to make sure it isnt a spurious match, if they pass then I consider it the title/author/date of the node. A bit of extraction of the tags attributes and presto, we have the home node and post node ids. (With the exception of the main post, where we can only extract the title, not the ID)

This would be sooooo much easier if there were class attributes in the tags, such as <TD class="post">, but considering the buggy HTML, I suppose class attributes are low on the priority list. (BTW, cant wait to join the PM dev team, id like to have a crack at cleaning up some of the HTML, now that im getting into parsing it :-)
