why would you store data thats wrapped in two copies of its fieldname
along with other punctuation? wouldn't it make more sense to
decompose your XML source into proper tables so proper indexes and
relational sql queries can be made? otherwise, every query turns
into a massive sequential scan and parsing operation.
