[LON-CAPA-dev] Extracting problems from page or sequence

[H. K. Ng]

|     while ($depth > 0) {
|         if($curRes == $iterator->BEGIN_MAP) { $depth++; }
|         if($curRes == $iterator->END_MAP) { $depth++; }
|
|         if (ref($curRes) && $curRes->is_problem()) {
| # What I want to do here is
| #(1) to get the sym name for each problem that is enclosed in the above
| #sequence/page,

~              my $symb = $curRes->symb();


I made some progress in the sense that I can now extract all the problems 
in a page. However, the symb name as called from $curRes->symb() has all 
the special characters returned as hex as given in the example below.

problemname=fsu%2fng%2f2053c%2dwinter2003%2fAssignment01%2epage___4___fsu%2ffsuphysicslib%2f2053c_w03%2fset1%2fmatchUnits%2eproblem

Question: Is there is function to convert it back?
