I would start by breaking this down into pieces.  Something like:

> data = Utilities.URLReader("http://sourceforge.net/projects/boost/files/boost/")

Now at least you get to look at what URLReader() returned.  Did it 
return what you expected?  If not, then there might be something wrong 
in your URLReader() function.  If it is what you expected, then I would 
start looking at the pattern to see if it's correct.  Either way, you've 
managed to halve the size of the problem.
