getExternProfileElement may suffer NullPointException

[lczxxx123]

Hi~
I found that in to/networld/android/divedroid/model/rdf/RDFParser.java , method protected String getSingleResourceNode(String _nodeName, String _resourceName) may return null if ( nodeList.size() > 0 ) , but in to/networld/android/divedroid/model/rdf/Buddy.java , private String[] getDiverProfileURI() use the ret without null check, may it cause NullPointerException when ret call method split ?

Thank you
