Text Signature Filter

Text Signature Filter looks for signature strings in HTML text. This filter is similar to two other signature filters: Script Signature Filter and Comment Signature Filter.

Parameters

string

One or more string parameters define a set of string signatures to look for. Currently only text enclosed in <table> and <div> HTML elements is examined. If at least one of the strings is found, the whole element is deleted.

Format:

string = text

See examples below.

string

One or more script_string parameters define a set of string signatures to look for within HTML <script> elements (that is between <script> and </script> tags). If there is a match the whole script is deleted. See an example below.

Format:

string = text

See also Common Filter Parameters.

Example

Consider this simple filter:

name = Ad Remover
enabled = true
logging = true
time = 
users = 
exclude_users = 
include = *
string = advertisement
string = a d v e r t i s e m e n t

Foxy web-based user interface will show the same filter like this:

This filter will efficiently delete HTML fragment below. The whole <table> element is deleted because one of the search strings (“advertisement”) was found inside.

<table>
  <tr>
    <td>
      = ADVERTISEMENT =
    </td>
  </tr>
  <tr>
    <td>
      <script language="JavaScript" src="/bannrs/random_ad.js"/>
      <noscript>
        <img src="/banners/6039743.gif">
      </noscript>
    </td>
  </tr>
</table>
