I am really a newbee in xml, and in fact a new bee in web programming
too. I am trying to develop a data warehouse with XML. I also need to develop
web pages that has a query form that allow users to search data in that warehouse.

For this purpose, what languages (eg ASP, PHP and etc) is recommended?
and what type of query language (SQL?) is "most compatible" with XML and
related languages (ie XSL and XML Schemas).
Thank you very much.
