How can we convert XML file to CSV?

Question

I am having an XML file

Answer 1

Use the straightforward SAX API via the standard Java JAXP package. This will allow you to write a class that receives events for each XML element your reader encounters.

Briefly:

1. read your XML in using SAX
2. record text values via the SAX DefaultHandler characters() method
3. when you get an end event for a COL, record this string value
4. when you get the ROW end event, simply write out a comma separated line of previously recorded values
