Web::Scraper::Filter(3pm) User Contributed Perl Documentation Web::Scraper::Filter(3pm)
NAME
Web::Scraper::Filter - Base class for Web::Scraper filters
SYNOPSIS
package Web::Scraper::Filter::YAML;
use base qw( Web::Scraper::Filter );
use YAML ();
sub filter {
my($self, $value) = @_;
YAML::Load($value);
}
1;
use Web::Scraper;
my $scraper = scraper {
process ".yaml-code", data => [ 'TEXT', 'YAML' ];
};
DESCRIPTION
Web::Scraper::Filter is a base class for text filters in Web::Scraper. You can create your own text filter by subclassing this module.
There are two ways to create and use your custom filter. If you name your filter Web::Scraper::Filter::Something, you just call:
process $exp, $key => [ 'TEXT', 'Something' ];
If you declare your filter under your own namespace, like 'MyApp::Filter::Foo',
process $exp, $key => [ 'TEXT', '+MyApp::Filter::Foo' ];
You can also inline your filter function without creating a filter class:
process $exp, $key => [ 'TEXT', sub { s/foo/bar/ } ];
Note that this function munges $_ and returns the count of replacement. Filter code special cases if the return value of the callback is
number and $_ value is updated.
You can, of course, stack filters like:
process $exp, $key => [ '@href', 'Foo', '+MyApp::Filter::Bar', &baz ];
