One additional remark: if the input can contain multiple stringAlias 
expressions on one line, the pattern should be /stringAlias="(.*?)"/ 
(note the question mark). You can see the difference if you match a 
string like

   str = "stringAlias=\"one\" bla stringAlias=\"two\""

   p str.scan( /stringAlias="(.*)"/ )
   # => [["one\" bla stringAlias=\"two"]]

   p str.scan( /stringAlias="(.*?)"/ )
   # => [["one"], ["two"]]
