title: Pugixml - Convert xml element content to C++ array
body: <p>In my xml file I have arrays of ints written as follows: "1 10 -5 150 35", and I am using pugixml to parse it.</p>
  
  <p>I know pugixml provides methods such as as_bool, or as_int, but does it provide an easy way of converting the string representation of an int array to a c++ object, or do I have to parse and separate the string myself? If so, any suggestions on how to do that?</p>
