Hello Daniel,
     You are right, but I still could not print out any thing from leaves
nodes,say text node. I used the function "xmlNodeIsText"to check if the node
is a leaf node. the output from my codes is:

nodename: text
         node content:

nodename: question
nodename: text
         node content:

nodename: answer
nodename: text
         node content:

nodename: question
nodename: text
         node content:

nodename: answer
nodename: text
         node content:

//---XML file used is -------

<?xml version="1.0"?>
<exam>
        <question>Who is the last King of England</question>
        <answer>George VI</answer>
        <question>How many queens were named Elizabeth </question>
        <answer>Two</answer>
</exam>

//----------------------------

Thank you very much

  You need to (re)read
  http://xmlsoft.org/#tree

Attributes and element nodes don't have content they have children,
Only leaves in the tree have content !
