  the best is to use the existing code part of the distribution.
In this case testXPath.c . The code do work:

orchis:~/XML -> cat tst.xml
<a><b foo="toto"/></a>
orchis:~/XML -> ./testXPath -i tst.xml '//*/@foo' 
Object is a Node Set :
Set contains 1 nodes:
1  ATTRIBUTE foo
    TEXT
      content=toto
orchis:~/XML -> 

  And the function testXPath() implementing it is not much longer
than yours.
