How can we convert XML file to CSV?

Question

I am having an XML file

Answer 1

Using XSLT is often a bad idea. Use Apache Commons Digester. It's fairly easy to use - here's a rough idea::

Digester digester = new Digester();

digester.addObjectCreate("Results/Row", MyRowHolder.class);
digester.addCallMethod("Results/Row/COL1","addCol", 0);
// Similarly for COL2, etc.
digester.parse("mydata.xml");

This will create a MyRowHolder instance (where this is a class you provide). This class would have a addCol() method which would be called for each with the contents of that tag.
