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. >From: ROSSEL Olivier <[EMAIL PROTECTED]> >Subject: RE: sexy open source >Date: Wed, 14 Aug 2002 17:10:03 +0200 > > > >I am currently studying XML DB features of Oracle 9iR2. > > >It is quite impressive. > > >Very very advanced stuff !!! > > > > > How it compares to Tamino and Xindice?
