VTD XMLRemoving the spaces after Removing the Element

We are using VTD XML for our application.Can you help us in solving the issue in our application.

The issue is: input xml:

    <root>
           <name>suresh</name>
           <address>Address</address>
    </root>


    output xml:

    <root>

          <address>Address</address>
    </root>

    But i want the output to be:

    <root>
          <address>Address</address>
    </root>

When i remove the element with xmlmodifier it is creating an empty space(new line) for the removed element.

Is there any possibility to remove that vtdxml?

Yes, there is, in version 2.12, there is a method called expandWhiteSpace in VTDNav, it works like the following

public final long expandWhiteSpaces(long l)

New in v2.12 This method will take a segment descriptor and return a new descriptor that includes all the leading and trailing white spaces around the input segment It has no effect on CDATA A typical usage would be 'expandWhiteSpaces(getElementFragment())' Parameters: l - upper 32 bits length of the segment, lower 32 bits offset of the segment, unit is byte offset Returns: a long 64 bit segment descriptor Throws: NavException

very thankful to Jimmy Zhang

I have provided the sample program about the usage.

import com.ximpleware.*;
import java.io.*;
public class testExpandSpace {
    public static void main(String[] args) throws VTDException,IOException{
        // TODO Auto-generated method stub
            VTDGen vg = new VTDGen();
            AutoPilot ap = new AutoPilot();
            XMLModifier xm = new XMLModifier();
            if (!vg.parseFile("d://xml//testSuresh.xml",false))
                return;
            VTDNav vn=vg.getNav();
            ap.bind(vn);
            xm.bind(vn);
            ap.selectXPath("//name");
            int index=-1;
            while((index=ap.evalXPath())!=-1)
            {
                System.out.println(" ===> "+vn.toString(index) +"===>");
                long elementFragment=vn.getElementFragment();
                xm.remove(vn.expandWhiteSpaces(elementFragment));
            }
            xm.output("d://xml//test1111.xml");
    }
}
