Eliminating Whitespace characters while parsing XML Files using DOM

Expand Post »

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 :

Java Syntax (Toggle Plain Text)

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

Coding :

Java Syntax (Toggle Plain Text)
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){}
    }
}
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 :

Java Syntax (Toggle Plain Text)
root ==> demo
sublistlength --> 3
sub name 0 :: #text
sub name 1 :: empid
sub name 2 :: #text
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:

Java Syntax (Toggle Plain Text)

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

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

Thanks

Re: Eliminating Whitespace characters while parsing XML Files using DOM

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.
