The underlying structure of the XMLDB repository is a blob, but why not…? The following…

Actually this is old stuff (2006), but it got lost in a comment section. I think this can still be useful to some and I also post this here for prosperity.
Somewhere in 2006 my colleague Lucas Jellema wrote a post on the AMIS Technology site about querying rss feeds from the database. My colleague Anton Scheffer and I commented on that article with our XMLDB functionality mindset. Later on in 2007 Lucas wrote another useful post called “Querying RSS feeds in SQL…“. Peter Wolf commented that he had also written a very nice blog post about using XMLDB functionality while Integrating Yahoo Pipes into APEX.
I think this is still useful stuff to a lot of us, although you should keep in mind that the table(xmlsequence(extract())) construct will be, in time, out lived by the XMLTABLE function. Also XMLTABLE supports XPath V2, the table(xmlsequence(extract())) doesn’t. The XMLTABLE function is available from Oracle database version 10.2.
I once started this website because of the steep learning curve regarding XMLDB functionality. After one year of existence the following posts were written by mean , for me as a notepad to remember what I have learned and or checked, tested or figured out and to pass it on to all those who are interested in XMLDB functionality as well.
I hope these posts, this list provided here, will be of help, to make those first steps or help designing a working and performing XMLDB environment. There is still a lot to describe and learn and hopefully I have time to cover these in the second year to come.
Have fun reading.
