pub fn detect_soap_fault(doc: &Value) -> Option<String>Expand description
Detect a SOAP <Fault> under Envelope.Body in a converted document and
return its message. Matching is namespace-prefix-insensitive (a fault under
soap:Envelope.soap:Body.soap:Fault and one under a default-namespaced
Envelope.Body.Fault are both detected). Returns None when there is no
fault (the normal success path).
