XML Query Language (XQL)

We believe that XML query languages can dramatically increase the utility of XML documents by providing powerful and convenient access to the information they contain. As more and more of our critical data is stored in XML documents, presented as XML documents through middleware, or made accessible via XML-oriented APIs, the ability to query XML documents becomes an essential aspect of being able to use the information we have. XQL is a query language based on the structure of XML documents. It is simple, easy to implement, and powerful. This paper explores scenarios in which XML queries might be performed, and presents a tutorial for the XQL query language.
