在java中，XML解析的最佳库是哪个

I'm searching the java library for parsing XML (complex configuration and data files), I googled a bit but couldn't found other than dom4j (Seems like they are working on V2).. I have taken look at commons configuration but didn't liked it, Other apache projects on XML seems under hibernation. I haven't evaluated dom4j by myself but just wanted to know - Do java has other (Good) open source xml parsing library? and how's your experience with dom4j?I'm searching the java library for parsing XML
