Objective C Error on #include <libxml/tree.h>

I am trying to setup a touchxml library and getting an error libxml/tree.h no such 开发者_JAVA百科file or directory. I added the linker flags and the header search paths as follow: /usr/include/libxml2 and linker flag -lxml2

I have looked all the documentation, but no go. Can someone help me on this?

Thanks

Ok I got it to work I was putting the /usr/include/libxml2 into User header search paths instead of header search path.
