REALbasic can export and import REALbasic projects in XML format. XML is a structured, text-based data format that provides a standard framework for representing data.For a brief orientation to XML documents in general, see What Do XML Documents Look Like?. The XML produced by REALbasic is well-formed, but it cannot be "validated" because it does not include a "document type declaration." Most of the content should be self-explanatory, with the aid of the reference below. Whitespace is significant only in the content area of the innermost tags; whitespace between one tag and another is not significant.http://www.realsoftware.com/support/xml
