Validating a xpath against xml

Question

try {
            DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
            Document document = builder.parse(new File("d:\\eqcschema\\test.xml"));
             XPath xpath =XPathFactory.newInstance().newXPath();         
            String expression = "//artinfo/pubinfo/pubname[1]";
            String pubname = (String)xpath.evaluate(expression, document, XPathConstants.STRING);
            //int val21=birthdateDouble21.intValue();
            System.out.println("Double is: " +pubname);
            expression = "count(//table)";
            Double nooftable = (Double)xpath.evaluate(expression, document, XPathConstants.NUMBER);
            int val2=nooftable.intValue();
            System.out.println("Double is: " +birthdateDouble2+"   "+val2);
            expression = "//table";
            NodeList birthdateNodels = (NodeList)xpath.evaluate(expression, document, XPathConstants.NODESET);
            for(int t=0;t<birthdateNodels.getLength();t++){
                Node table=birthdateNodels.item(t);
                expression = "tgroup/@cols";
                String expression1 ="count(tgroup/colspec)";
                Node cols = (Node)xpath.evaluate(expression, table, XPathConstants.NODE);
                System.out.println("Node sdsddssd is: " + cols);
                int colsvalue=Integer.valueOf(cols.getNodeValue());
                Double colspec = (Double)xpath.evaluate(expression1, table, XPathConstants.NUMBER);
                int val1=colspec.intValue();
                System.out.println("Node sdsddsssasad is: " +colspec+"   "+val1);
                if(colsvalue==val1){
                  System.out.println("It is Equal ");
                else{
                       System.out.println("It is Not Equal ");
            }this is how i use the xpath. is it ok using likie this.
but the problem here is .. i could display the required message but how do i get the node's line number???
is there anyother way to capture the line number????
