Which XML Parser Do You Recommend?

tshieh asks: "I'm trying to add XML-configurability to a Java application, and I'm trying to figure out which XML parser I should use. Any thoughts on whether I would be better off using Xerces, expat, XML4J, or JDOM (or any others)? So far, I've decided to use DOM rather than SAX since I've heard that DOM is easier to use and I don't anticipate my configuration file becoming so large that the slower and more memory-intensive DOM parsing becomes an issue."
