Re: Correct value of parameter uploaded_file

What about "output=soap12" for xml result in multipart/form-data POST?

 

I wrote a code which sent multipart/form-data POST for Validate by File
Upload validation mode. It works and returns html result from
validator.w3.org

but I cannot get xml result.

 

Is there any help?

 

And sometimes I get prolog error. Why?
