To add to this.

Oracle 9i now has a native XMLType which is really a CLOB. However, it 
doesn't have the normal limitations of a CLOB -- you can use XPATH for 
selection and for indexing, a great improvement in my opinion. However, a 
drawback remains in that you are still unable to select individual nodes and 
attributes within the CLOB, so your SQL has to return the document as a 
whole.

Another drawback is that the Java API provided by Oracle is for 1.2, thus 
lacking regular expression support.

Also, XML has to be updated as a whole, as Oracle still has nothing like 
XUpdate.

Oracle is catching up to Xindice but still a ways back, in my opinion.
