Detailed Description

xmlTextReader based interface to iterate xml streams.

 // Consume a node.
 bool consumeNode( XML::Reader & reader_r )
 {
   DBG << *reader_r << endl;
   return true;
 }

 // Consume all nodes (omitting attributes)
 void example()
 {
   try
     {
       XML::Reader reader( "/Local/repodata/repomd.xml" );
       reader.foreachNode( consumeNode );
     }
   catch ( const Exception & )
     { ; } // parse error
 }

 // Consume a node.
 bool consumeNodeAndAttribute( XML::Reader & reader_r )
 {
   consumeNode( reader_r );
   return reader_r.foreachNodeAttribute( consumeNode );
 }

 // Consume all nodes and thair attributes.
 void example()
 {
   Pathname repodata( "/Local/repodata/repomd.xml" );
   try
     {
       XML::Reader reader( "/Local/repodata/repomd.xml" );
       reader.foreachNode( consumeNodeAndAttribute );
       // or:
       // reader.foreachNodeOrAttribute( consumeNode )
     }
   catch ( const Exception & )
     { ; } // parse error
 }
