I asked one of my students to solve the randomization part of my problem; he did so very quickly!
Is there a parameter that one can pass to html2xml that will make it so that the solution link is not displayed? Where can I find a list of all the valid parameters one can pass to html2xml?
To use the javascript included below, do this:
<html><wwproblem
width="750"
height="800"
probpath="path/to/problem/problem.pg"
course="coursename"
userid="userid"
password="password"
wwroot="https://yourschool.edu/webwork2"
seed="123456789">
</wwproblem>
<script src="path-to-javascript-file-below"></script>
</html>

function set_random_source(probID) {

var prob = document.querySelector('wwproblem[probID="' + probID + '"]');
var fr = prob.querySelector('iframe[probFrameID="embeded-window-' + probID + '"]');
var wwroot = prob.getAttribute('wwroot');
var probpath = prob.getAttribute('probpath');
var course = prob.getAttribute('course');
var userid = prob.getAttribute('userid');
var password = prob.getAttribute('password')
fr.src = wwroot + "/html2xml?&answersSubmitted=0&sourceFilePath=" + probpath + "&displayMode=MathJax&courseID=" + course + "&userID=" + userid + "&course_password=" + password + "&outputformat=simple&problemSeed=" + seed;

var problems = document.getElementsByTagName('wwproblem');
for (var i = 0; i < problems.length; i++) {
var prob = problems[i];
var width = prob.getAttribute('width');
