6144XML Document to SOM object trouble

      Hello, I was wondering if anyone might be able to offer some insight
      on my problem.

      I am writing tests for a perl script which relies on SOAP to send and
      receive data from a server. In an effort to simplify the tests and
      isolate the server from consideration, I am trying to simulate the
      server's xml responses using locally stored xml files rather than
      actually calling the server's methods. In effect, this will allow me
      to feed custom server messages into the script so that I can more
      easily control and analyze the output.

      To do this, I have written a custom perl object with nothing but a
      'call' method. My script will instantiate this object in place of the
      usual SOAP::Lite object. My call method will accept the parameters,
      read the appropriate XML file, and return a SOM object as if the call
      had really gone through to the server.

      My problem is with the creation of this SOM object. According to:

      $som = SOAP::SOM->new($message_as_xml);
      As said, the need to actually create an object of this class should be
      very rare. However, if the need arises, the syntax must be followed.
      The single argument to new must be a valid XML document the parser
      will understand as a SOAP response.

      My case seems to clearly be one of these rare needs. I have tried
      passing just about everything I can think of into this method through
      the $message_as_xml parameter, but I am constantly getting error
      messages such as "Not an ARRAY reference at
      /opt/perl5.6.1/lib/site_perl/5.6.1/SOAP/Lite.pm line 385" and "Can't
      use string ("<?xml version='1.0' encoding='ut") as an ARRAY ref while
      "strict refs" in use at
      /opt/perl5.6.1/lib/site_perl/5.6.1/SOAP/Lite.pm line 385".

      I have tried passing the xml directly as a file, as a string, as a
      number of pre-parsed xml objects, arrays, and others, as well as a
      string representing the file name, and anything else I could think of,
      but there appears to be no information available about what exactly
      this needs to be. I've tried looking at the perl lite code itself to
      get a clue, but I'm afraid I'm not quite good enough of a perl
      programmer to glean any clues.

      Would anyone be able to show me a simple example of how to use this
      method to create a SOM object from a valid XML file? I'd be extremely
