Perl syntax and html ole parsing

[wakatana]

Hi gurus
I am trying to understand some advanced (for me) perl constructions (syntax) following this tutorial I am trying to parse html:
Using Mojo DOM | Joel Berger [blogs.perl.org]

say "div days:";
say $_->text for $dom->find('div.days')->each;

say "\nspan hours:";
say $_->text for $dom->find('span.hours')->each;

What does this syntax mean, what is going on here ?
- What kind of loop is this, classic for construction looks like this: for(i=0;i<10;i++){ code } not: {code} for (some_condition)
- What does "each" keyword mean in this context ? Does it have somethin common with "each" build in perl function
each - perldoc.perl.org or it is specific to Mojo:OM ?
IMHO on Mojo:OM homepage I did not found any mention about "each" under methods section Mojo DOM - search.cpan.org
so it must be a build in function of perl, but this buildin "each" function has completelly different syntax, how is this possible, am I missing somethin ?



Another example from tutorial page

say "Open Times:";
say for $dom->find('div.openTime')
            ->map(sub{$_->children->each})
            ->map(sub{$_->text})
            ->each;

Same issue as above for "map" and "sub" methods
map - perldoc.perl.org sub - perldoc.perl.org



- Can be those pieces of "Perlish" code rewriten in more "C specific" maner so I can understand it?
- Most important: How to list all methods their parameters and return values contained in Mojo DOM ?
it must be done somehow, because I read that even for perl there are IDE with intelisense (autcompletition) so this IDE must know the methods return value types etc.



Thank you very much

Hi, Makatana,

I cannot answer your final two questions, but about the "each" method in general, have a look here, Mojo:OM - search.cpan.org, which leads to here, Mojo::Collection - search.cpan.org. Basically, each is a method of a Mojo::Collection object as returned by the "find" method of Mojo:OM.

say would be a method/subroutine in the module mojo-dom which should be on the @inc array in your server or you need to change the configuration and add it to the server @inc array if it is configured for PERL.
say (at a guess) is a method to take text and place it in HTML elements then print() to STDOUT.
