Eliminating Whitespace characters while parsing XML Files using DOM
 

Hi all ,

I'm having problem during parsing xml files using DOM API due to whitespace characters.

Here is my sample XML File ,coding and output :

XML File :

<demo>

    <empid>e100</empid> 

     </demo>

Coding :

import java.io.*;

import org.w3c.dom.*;

import org.w3c.dom.Node;

import org.w3c.dom.NodeList;





import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.parsers.DocumentBuilder;



class demo{

    public static void main(String args[]) throws IOException {

        try {

        DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();

        DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();

        Document doc = docBuilder.parse(new File("C:/Documents and Settings/t48ezi/Desktop/demo.xml"));

        

        Element rootElement = doc.getDocumentElement();

        System.out.println("root ==> "+rootElement.getNodeName());

        NodeList sublist = rootElement.getChildNodes();

        System.out.println("sublistlength --> "+sublist.getLength());

        System.out.println("sub name 0 :: "+sublist.item(0).getNodeName());

        System.out.println("sub name 1 :: "+sublist.item(1).getNodeName());

        System.out.println("sub name 2 :: "+sublist.item(2).getNodeName());

        

        }

        catch(Exception e){}

    }

}

Output :

root ==> demo

sublistlength --> 3

sub name 0 :: #text

sub name 1 :: empid

sub name 2 :: #text

I have only one chid but i got the number of child of rootelement as "3" due to whitespace character as shown in output(#text) but when i manually type XML Files in LINEAR fashion means i'm getting correct output .

LINEAR FASHION XML FILE:

<demo><empid>e100</empid></demo>

but i used a code that automatically generate xml format . So , how to eliminate that (#text) ?

Thanks

You don't. You rather learn to use the XML parser properly and explicitly read only those elements from the tree that you actually need.
