I need to read an XML file using Java. Its contents are something like
C:/Input.csv
Another suggestion: Try out Commons digester. This allows you to develop parsing code very quickly using a rule-based approach. There's a tutorial here and the library is available here
I also agree with Brian and Alzoid in that JAXB is great to get you up and running quickly. You can use the xjc binding compiler that ships with the JDK to auto generate your Java classes given an XML schema.
