HTTP::Proxy::BodyFilter::htmltext.3pm

NAME

HTTP::Proxy::BodyFilter::htmltext - A filter to transmogrify HTML text

SYNOPSIS

     use HTTP::Proxy::BodyFilter::tags;
     use HTTP::Proxy::BodyFilter::htmltext;
 
     # could it be any simpler?
     $proxy->push_filter(
         mime     => 'text/html',
         response => HTTP::Proxy::BodyFilter::tags->new,
         response => HTTP::Proxy::BodyFilter::htmltext->new(
             sub { tr/a-zA-z/n-za-mN-ZA-M/ }
         )
     );
 
 

DESCRIPTION

The HTTP::Proxy::BodyFilter::htmltext is a filter spawner that calls the callback of your choice on any HTML text (outside "<script>" and "<style>" tags, and entities).

The subroutine should modify the content of $_ as it sees fit. Simple, and terribly efficient.

METHODS

The filter defines the following methods, called automatically:

init()

Ensures that the filter is initialised with a CODE reference.

begin()

Per page parser initialisation.

filter()

A simple HTML parser that runs the given callback on the text contained in the HTML data. Please look at HTTP::Proxy::BodyFilter::htmlparser if you need something more elaborate.
