Re: PostgreSQL's XML support comparison against other RDBMSes

May I ask a question about this?

I will be working on an older database in which the original developer stored XML documents as a single variable length text field. To process it, it has to be retrieved in full and parsed. But the structure of it is simple in that it has an element for each field in the DB that replaced the earily version. But people are still using the earlier one because they still need access to the old data and no tool has yet been written by my predecessors to move the old data over to the new DB. Does the XML support you're all talking about make it less tedious to develop tools to parse these old XML files and put their data into the right field of the right table? I can develop the tool our users need using the resources I have at hand, but the proces of parsing these XML files is certain to be very tedious; something I am not looking forward to. There is a reason I don't do much with XML even though I know how.

The first step would be making a detailed analysis of what "XML support"
is supposed to mean.

So let's make such analysis here within PostgreSQL community! There
were a lot of talks about XML support in Postgres, but they did not
lead to any steady work in this direction. IMHO, it's time to start it
now, no?

The people who want it should explain what it is, ideally by
pointing at the relevant standards documents.
