title: Objective C Error on #include <libxml/tree.h>
body: <p>I am trying to setup a touchxml library and getting an error libxml/tree.h no such file or directory. I added the linker flags and the header search paths as follow:
  /usr/include/libxml2
  and linker flag
  -lxml2</p>
  
  <p>I have looked all the documentation, but no go. Can someone help me on this?</p>
  
  <p>Thanks</p>
