With VFP, you can easily create XML, since it is really just a string of text.

You will find excellent explanations and white papers that are VFP-specific at West Wind's site:

Also, download the free wwXML classes from West Wind, for great tools to convert from VFP cursors to XML and vice versa.

VFP7, due out very soon, will have similar functions like XMLTOCURSOR and CURSORTOXML.

And, you will find regular coverage of XML in every issue of Component Developer Magazine (CoDe) at www.code-magazine.com.
