Thanks for sharing this, Mike. I will take a look. I was caught off-guard by the lack of a query parser. The only other XML database I've worked with, Textml Server, does have one.
It's obvious now after seeing your approach, but my initial reaction was to try and parse the query in XQuery. That may not be the best idea. Thanks again! On 5/9/07, Mike Sokolov <[EMAIL PROTECTED]> wrote:
Ours is here: http://www.ifactory.com/cql/. It does AND, OR, NEAR, quoting, and various other good things. It generates a cts:query, making some assumptions you may or may not like... We have some updates in an internal version that we could make available if there is interest. There is also another parser out there in the xqzone that Ryan Grimm made, (I think?)
