The Cocoon publishing framework (http://xml.apache.org/cocoon) has something that does exactly what you want: http://xml.apache.org/cocoon/sqltaglib.html You embed the XML-formatted SQL query in a page, eg: <sql:execute-query> <sql:driver>com.informix.jdbc.IfxDriver</sql:driver> <sql:dburl>jdbc:informix-sqli://localhost:1526/database:informixserver=server</sql:dburl> <sql:username>dbUser</sql:username> <sql:password>dbPass</sql:password> <sql:query>SELECT * FROM CUSTOMER;</sql:query> </sql:execute-query> When the user requests that page, they get back the query results marked up as XML. There can be intermediate stylesheets to format the output too. There's also an equivalent tagset for querying LDAP, and another for reading/writing XML files, where nodes are specified with XPath expressions. All Open Source, works really well. --Jeff On Tue, 14 Nov 2000, Michel Rodriguez wrote: > Hi, > > I was wondering whether some work, maybe standardization work, has been > done on embedding data from a relational database into an XML document. > The document is processed to generate the complete XML document, but the > non-processed version is the one that is edited and managed in the system. > > I have found no trace of public work on that topic, although I know of a > couple of old SGML implementations. > > I realize that various type of results can be required, from a single > value to a complete table, through one or more rows or columns (columns > being even trickier than rows).
