If you are calling wwXML as a COM object from your ASP, you have to return the contents using Response.BinaryRead (wwXMl will have to be modified to retrurn its dataset using CreateBinary). If you are calling a VFP COM object from ASP and returning the binary contents, you have to use VFP's CreateBinary function to convert the VFP string to a Binary string that you can pass back to your ASP script.

All this assumes that wwXMl provides for holding the binary data correctly with the CDATA directive, which I don't think that it handles correctly. I suggest that you use CreateBinary, BinaryWrite and Encode/DecodeDBF to handle this to take the XML confusion out of the picture (even if Rick wrote his class correctly, we don't know for sure that msXML will correctly handle the parsing when it sees the binary data).
