Subject: Parsing query parameters from hyperlink

I am trying to parse strings like this
<a href='showmono.asp?cpnum=1022&ampmonotype=comb' target='main'>

I need to get the cpnum value (555)

I am using the following function

def get_drugId(link)
     arrParts = link.html.split('?')
     cpnum = arrParts[1].split('&amp')
     cpnumparts= cpnum[0].split("=")
     drugId = cpnumparts[1]
  end

but I imagine there is a simpler way to do this. Also, I would like
something more flexible that would return all the query parameters (if
there are more than one) in an array or a hash.

Any ideas?

thanks,

Luis
