Java JAXP or Xerces2 for XML process?

I am using Java 6 and want to process (read and write) xml files (small files) within my Java application. Should I use Java JAXP or Apache Xerces2? According to this post, https://stackoverflow.com/search?q=JAXP+vs+Xerces

Java 开发者_JAVA技巧6 use Xerces already. How about Xerces2? big different between Xerces (Java 6 JAXP) and Xerces2? Either should be fine to me and I just want to start with a good one.

I suggest using JAXP since it's standard in the Java JDK. No need for external libraries
