thnx for ur relpy with sample eg.
  but how could i use the parameter as Configuration instance in XPathEvaluator it is expecting a Evaluator. 
it is showing error in that line .. XPathEvaluator..
one more ques.
can i set this configuration to a node i Parse.?


Configuration config = new Configuration();
>config.setLineNumbering(true);
>XPathEvaluator xpath = new net.sf.saxon.xpath.XPathEvaluator(config);
