how to use DOM Parser

[vanita maram]

Hi

I am trying to create a program to divide a big xml docuents into smaller xml as the main document file has similar child elements but different values for the elements. Somebody told me to use DOM Parser to do it. I have xmlSpy installed on my machine but that doesnot have any feature which lets me create breaks in the documents. Can somebody please tell me how to use DOM Parser and give a sample code if they have created for the same purpose.

Thanks
Vanita

Use a JDOM Parser and some Java programming. I dont know what you are trying to achieve but maybe the following code snippets can help:

public static void BeginConversion(String name)
{
   try
{
  SAXBuilder builder = new SAXBuilder(false);
  builder.setValidation(false);
  Document doc = builder.build(name);
// Gets the root element of the document and then proceeds to create
// the elements available within this root element
  Element root = doc.getRootElement();
  List subelements = root.getChildren();
  Iterator elements = subelements.iterator();
// Iterates through the list of elements within root
  while(elements.hasNext())
{
  Element subelement = (Element)elements.next();
  if(subelement.getQualifiedName().equals(Your element name))
{
   // Do whatever you want to do here
                        }
}
catch (Exception e) {e.printStackTrace();}
}

Hope this helps.

You might want to look over Sun's tutorial on XML processing with Java.

Do you want to split each of these specified child elements into a separate document?

Perhaps splitting the document is not the best solution - what are you actually trying to do with the data?

Hello vanita maram,

Welcome to JavaRanch!

This Sun's J2EE Tutorial is a very good one which explains step by step approach of using DOM.

Hope this might help you.
