I don't doubt that there are some people in the world who want to "mine" documents, but I think that they are in the minority, and will be for a long time. But more important, it makes little sense to me to "mine" XML data. Even if you wanted to mine your structured document data it will almost always make sense to load that into the mining tool's internal data structures. Once again, XML is great as the transfer format, but when you get down to doing your queries, your data mining software should not be parsing the XML syntax. > However, let me ask a technical > question that you can probably answer with a deeper > technical perspective than mine?

In some cases you can do sophisticated queries on data without a schema, but you would have to jump through AI hoops. It's not a job I would apply for, but neural net experts may be able to detect structure in the chaos. But building the schema first is definately cheaper than trying to divine the structure later.
