[madhuri kunchala]

can anyone help me im waiting for the reply..where my code goes wrong..

[Prasad Krishnegowda]

Hi Madhu,

Just comment out this

  Document doc =null;  

and change this line

 DOMSource source = new DOMSource(doc);   

to

  DOMSource source = new DOMSource(parent);     

in delNode function...

[madhuri kunchala]

hi,
thanks for your reply..i tried it is deleting only one line...in my xml file i need to delete whatever pack name entered...it should delete..here im attaching my xml file..if you see my xml file you'll see <MA98>,<MA99>,<MA03>..i need to delete <MA03> means that file should not be there..can you tell me where to do

[madhuri kunchala]

prasad have you seen my xml file and suggest me how to do for deletion of 'Pack 1 or other packs'...

[Prasad Krishnegowda]

For that, You need to have a for loop inside if (child.getNodeName().equals(filter)) and get all its child elements one by one and delete them...

[madhuri kunchala]

kk..i'll try i had another doubt..is i had done modification..but the modification is happening at the end of my xml file...but i need is i used to enter the 'Pack Name' in jsp page..by taking that 'Pack Name' it should check and it should do modification at that pack place...i had used for loop..but im unable to get it...here is my code..for modification

Sorry but my response is not related to your problem. But I was wondering why this method signature is like this? I mean bunch of parameters? Why dont you have a single or some less number of objects which contains these parameters? You are forcing method users to type all the parameters (I know now its private method)?
