Store and convert heavy XML data in MSSQL

I want to use XML data (productinformation) for my website. All XML files are available for download so i want all data stored in 1 local database. The information from this database will be used to: - Show data on oscommerce website by request (html search engine friendly) - Provide data converted to plain Txt on request - XML data stored should be available for product datasheet comparison (html generated) Only apply if you have experience in working with XML and keeping Database up to date with the XML updates/information. This is an urgent job so you should really be available for this. Mention 'XML_Job' when sending PM message (to avoid fake/robot postings)
