You can't. The soap calls have a soap:envelope tag around them, which makes them useless as xml documents because there isn't any XSD to which they conform (unless you hack your way around the existing XSD and WSDL to make this work, which is kinda ugly)
Upload the files using the file manager, so you have them available as a FileDocument. Then make a microflow and use the 'Import XML Document' activity, select the FileDocument containing the XML and select which XML-to-Domain mapping you want to use.
