Fixes #97

The main issue was for non-element nodes the ns and nsDef structures can be non-null but also invalid as XML_ATTRIBUTE_NODE cannot have its own attributes or namespace definitions. The code assumed they would be NULL but that is clearly not true.

The fix is to only check for attributes if it is an XML_ELEMENT_NODE and return character() otherwise.

One other issue this raises is how we want display non-element nodes. Should format(t1) be "c='1'" or is the previous behavior as <c> sufficient. Most of the time I believe people want to work with element nodes, so probably the previous behavior is fine.
