in reply to The State of Web spidering in Perl

Speaking of good and old, what about LWP instead of WWW::Mechanize, and HTML::Parser instead of HTML::TreeBuilder? I have a bunch of production code that uses it, and it's been working flawlessly (modulo the bugs we introduce ;) for over a decade...

    I'll give HTML::Parser a second look, thanks for the suggestion. How do you match something like //div[@id='blah']/p though, do you explicitly maintain state?

    As for LWP vs Mech, LWP does work for my use case, I just prefer Mech for a few niceties like autocheck, auto-delegation of $mech->content() to $response->decoded_content(), cookie_jar defaulting to on, etc.

[shmem]: wait, what? you want that person to read the documentation for you?
[Lady_Aleena]: I might have to go with options instead of a straight list.
[Discipulus]: if more than 3 go for named variables LA
[Lady_Aleena]: Discipulus, it is at 2 now, but with what I am thinking about, it could go to 3. However, only 1 is needed. The second and third are optional.
[shmem]: straight list or named parameters - that depends on whether (and how many) optional arguments you have
[Discipulus]: if so a plain list is ok, imho
[Lady_Aleena]: shmem, I already have the plugin installed, just not active.
[shmem]: if you have 1 optional argument, place that at the end of the list. If you have more, go for named parameters.
[Lady_Aleena]: 1 manditory, 2 optional.
[Discipulus]: my ($need,$opta,$optb ) = @_; .. if $opta..
