E-XMLMedia
http://www.e-xmlmedia.com/home/index.htm
E-XMLMedia develops and distributes an XML toolkit for the manipulation of XML documents as data and for the manipulation of data as XML documents. XML documents and arbitrary fragments of documents are published, exchanged, stored and queried. In addition, arbitrary data sources are "wrapped" so that they appear to be repositories of XML documents. This functionality is provided in a single, integrated, coherent toolkit. The result is a platform for the manipulation of XML as document and the manipulation of data as XML.
