Description
Data provided by the Open University includes HTML mark up tags in certain fields. These must be removed before the information can be reformatted for sending to recipients. The majority of conversions include the use of text files which are tag stripped using a Perl script. The Perl script also eliminates entity references and puts ASCII text in their place. Additionally, certain output formats use only MS Access and not text files. For these outputs, tags are removed with MS Access macros.
