This is essentially the same solution as used in Ultraseek Server. The "XML Mappings" page in Ultraseek Server is a bit simpler, because we didn't want to restrict our customers to "people who can write XPath expressions". We can map from an element name, or an element name restricted to an attribute with a particular value. This handles cases like <abstract> and <div1 type="abstract">, which is a huge subset of real-world DTDs. I think of them as "meta data elements", using the Dublin Core terminology, but the model is the same. Quick, call it a Design Pattern and let's publish a book. wunder -- -- Walter R.
