How can I generate a .xml from a DTD and a form?

[wxdqz]

hi'I have been asked by a friend to solve a little pb but I'm abeginner in XML:I have a DTD which describes data fields (such as "name","article", "product"(=f(name, article)), etc...).And I want to generate a .xml file from a Form-type Query,with matching fields (I want as much fields in my .xml as queries).Obviously it must be a valid document.Do you know a tool which can generate it that way?or do you know an easy way to implement that kind of tool?Thank You for your helpSocrates (France)
