  2. Need • Resolving conflicts is frustrating! • Using the online Master Schedule is tedious! • Why not parse the SAS Master Schedule, and let the computer find a course that meets your needs?

  3. User Interface • Access the webpage from any browser. • Narrow the search by selecting search criteria from a web interface. • Choose a course from the results list, or go back and search again.

  4. Selection Options • Undergraduate or Graduate • School • Department • Professor • Day • Time • Course Number

  5. Programming Overview • Development Environment • UNIX • Scripting • Perl • CGI • Web page design and documentation • HTML

  6. From SAS to Usable • Perl script • Parses the SAS Master Schedule to get rid of HTML tags and garbage lines. • Parses new file to reformat and keep the most important information. • Parses the clean file using the criteria entered by the user. • Returns the results with Dynamic HTML.

  10. Script - Professor List cat $1 | sed 's/<.*>//g' | /usr/xpg4/bin/sed "/\^\$/d" | grep "[A-Z][A-Z][0-9][0-9][0-9]." | sed '/HTBA/d' | awk -f getProf | sort | uniq > $2 #!/usr/xpg4/bin/awk –f getProf { print $NF }

  11. Dynamic HTML – Professor List print " Select a Professor:<br>"; print " <select name=\"Professor\">"; print " <option value=\"none\">"; open(INPUT,"professors.txt") || die("Can't open professors.txt"); while(<INPUT>) { print "<option value=\"$_\">"; print $_; } print " </select><p>";

  12. Comparing Professors $pos=length $professor; $l=$pos-1; if($l == $thisLength) { $i=0; while(($thisProf[$i] eq $splitProf[$i]) && ($i<($l))) { $i++; } if($i==$l) { $keep=1; } else { $keep=0; } } else { $keep=0; }
