NAME
    HTML::StripTags - Strip HTML or XML tags from a string with Perl like
    PHP's strip_tags() does

SYNOPSIS
     use HTML::StripTags qw(strip_tags);

     $string       = '<html>Hallo <u>beautiful</u> <a href="http://worldonline.com">world</a>!</html>';
     $allowed_tags = '<u><b>';

     print strip_tags( $string, $allowed_tags );

DESCRIPTION
    HTML::StripTags provides the function strip_tags() that can strip all
    HTML or XML tags from a string except the given allowed tags. This is a
    Perl port of the PHP function strip_tags() based on PHP 5.3.3.

SECURITY NOTE
    Please note: As per <http://htmlpurifier.org/comparison#striptags> PHP's
    strip_tags() is a very basic and unsafe method, so it's strongly
    recommended not to use it for cleaning up user input! As HTML::StripTags
    uses the same state machine, the same applies to this module.

METHODS
  strip_tags()
    A simple little state-machine to strip out html and php tags

    State 0 is the output state, state 1 means we are inside a normal html
    tag, state 2 means we are inside a php tag, state 3 means we are inside
    a "<!--", case 4 means we are inside the following JavaScript/CSS/etc.
    tag.

    When an allow string is passed in we keep track of the string in state 1
    and when the tag is closed check it against the allow string to see if
    we should allow it.

     print strip_tags( $string, "<u><b><?php<?" );

     print strip_tags( $string, ('<u>', '<b>', '<?php', '<?') );

TODO
    Pass in state variable to allow a function like fgetss() to maintain
    state across calls to the function.
    Implement fgetss().
