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 ]; AUTHOR
