This is a brief tutorial about how to write wrappers for the TElegraph Screen Scraper (TESS).

Some assumed knowledge

  • Basic regular expression.
  • Some familiarity with the stucture of HTML
  • The general ability to create files/directories and run programs.
    A basic wrapper for TESS is contained within a .jsc file. This file is basically a collection of regular expresions that tells TESS how to parse the data and information about where TESS can find the data. This is represented with a series of directives of the form directive_name=value.


  • A step by step example of creating a wrapper.
  • Testing and debuging wrappers
  • A list of the currently supported directives and a brief description of what they do.
