The KTH Computer Science Master program page (http://www.kth.se/student/kurser/program/TCSCM/HT10/kurslista) should be considered broken in it's current state. This code will fix it.

Fix crappy course lists.js

// For use on sites with crappy KTH course lists like 
// http://www.kth.se/student/kurser/program/TCSCM/HT10/kurslista

var body = document.getElementsByTagName("body")[0];
function buildCourseLink(courseCode) {
  // Clumsy way of finding the course title but it works
  $.get("/student/kurser/kurs/" + courseCode, function (coursePage) {
		var title = $(coursePage).filter('title').text().replace(/^KTH \| /, "");
		$('.' + courseCode).text(title);
	});
  // Wrap each course in a properly classed anchor that can be found by jQuery once we've found the course title
	return '<a class="' + courseCode + '" href="/student/kurser/kurs/' + courseCode + '">' + courseCode + '</a>';
}
function buildReplacement(crappyChunkOfCourseCodes) {
  // Get some linebreaks in there
  crappyChunkOfCourseCodes = crappyChunkOfCourseCodes.replace(/(,|(\s|&#160;|&nbsp;))+/g, '<br/>');
  // Look up the coursenames with the function above
	var neatListOfLinkCoursenames = crappyChunkOfCourseCodes.replace(/[A-Za-z]{2}\d{4}/g, buildCourseLink);
	return neatListOfLinkCoursenames;
}
var replacementBody = body.innerHTML.replace(/<p>\w*([A-Za-z]{2}\d{4}(,|(\s|&#160;|&nbsp;))*)+\w*<\/p>/g, buildReplacement);
// Fix some spelling mistakes
replacementBody = replacementBody.replace("sysem", "system");
body.innerHTML = replacementBody;
