problem when reading a file...

I'm trying to read out a file, in which some data is stored.
Format is this:

name < value > ... ;

But when I run the following code:
Expand|Select|Wrap|Line Numbers
  1. std::string token;
  2.     while (is >> token && token != ";")
  3.     {
  4.         if (valMap.find(token)!=valMap.end())
  5.         {
  6.             std::string dump;
  7.             is >> dump;
  8.             assert (dump == "<");
  9.             is >> dump;
  10.             std::cerr << dump << std::endl;
  11.             valMap[token] = dump;
  12.             while(is >> dump && dump != ">")
  13.             {
  14.                 valMap[token] += " " + dump;
  15.             }
  16.         }
  17.     }
  18.  
no values can be found in the map.
Additionally, the code in the loop is never executed, the checking for
(is >> token) seems to fail.
Calling clear() on is does not help.

Where "is" is std::ifstream and valMap std::map<std::string,std::string>.
valMap contains "name" form the data file in the first component.

Btw, I run a similar function right before, to collect all the names from the file, which runs just fine.

PS: Actually, th function I run before is the same but with a map containing just the tag from the first column of data
