Howto adjust filter settings

[timmy01]

hi!
I am trying to filter a load of old static html pages of mine
back into the database.
The script i am using now can only filter 1 tag of each record.

Suppose: page holds 10 records, every record has got 1 tag <b></b>
Simultaneously i want to filter also all thats within the tag <i></i>

Obviously i have to start with adding some extra variables:
$config['start_tagB'] ="<i>";
$config['end_tagB'] ="</i>";

but how to implement this with in the function

<?php

$config['url']    = "http://www.sample.com"; // my domain
$config['start_tag'] = "<b>"; // start
$config['end_tag']  = "</b>"; // end

class grabber
{
  var $error = '';
  var $html = '';
  
  function grabhtml( $url, $start, $end )
  {
    $file = file_get_contents( $url );
    
    if( $file )
    {
      if( preg_match_all( "#$start(.*?)$end#s", $file, $match ) )
      {        
        $this->html = $match;
      }
      else
      {
        $this->error = "Tags cannot be found.";
      }
    }
    else
    {
      $this->error = "Site cannot be found!";
    }
  }
  
  function strip( $html, $show, $start, $end )
  {
    if( !$show )
    {
      $html = str_replace( $start, "", $html );
      $html = str_replace( $end, "", $html );
      
      return $html;
    }
    else
    {
      return $html;
    }
  }
}

$grab = new grabber;
$grab->grabhtml( $config['url'], $config['start_tag'], $config['end_tag'] );

echo $grab->error;

foreach( $grab->html[0] as $html )
{
  echo htmlspecialchars( $grab->strip( $html, $config['show_tags'], $config['start_tag'], $config['end_tag'] ) ) . "<br>";
}

?>

hope you can help out
as it will safe me lots of time

You could pass an array of elements that you want stripped and use a regular expression to remove all possible values. Something along the lines of

$pattern = '/<\/?(b|i)>/';

Of course, you would build the pattern tag values dynamically, but that should get your mind started in the right direction.
