    - #### getPublicId

          public java.lang.String getPublicId()

      Return the public identifier for the current document event.

      The return value is the public identifier of the document entity or of the external parsed entity in which the markup triggering the event appears.

      Specified by:
        `getPublicId` in interface `SourceLocator`
      Specified by:
        `getPublicId` in interface `Locator`
      Overrides:

      Returns:
        A string containing the public identifier, or null if none is available.

        `getSystemId()`

    - #### getSystemId

          public java.lang.String getSystemId()

      Return the system identifier for the current document event.

      The return value is the system identifier of the document entity or of the external parsed entity in which the markup triggering the event appears.

      If the system identifier is a URL, the parser must resolve it fully before passing it to the application.

      Specified by:
        `getSystemId` in interface `SourceLocator`
      Specified by:
        `getSystemId` in interface `Locator`
      Overrides:
