[Simple-support] Supporting different root elements

[Jarrod S. <ja...@co...>]

I have to parse server responses that where the body of the document is the
same, but the document root node can change depending on whether the
request resulted in errors:

e.g. Success response:

*<OK>*
      <ELEM1>Data</ELEM1>
      <ELEM2>Data</ELEM2>
      ...
*</OK>*

Error response:

*<FAIL>*
      <ELEM1>Error information for ELEM1</ELEM1>
      <ELEM2>Error information for ELEM2</ELEM2>
      ...
*</FAIL>*
*
*
How can I support this using Simple? I don't want to have to sniff the
input stream and switch classes based on whether I find an <OK> or <FAIL>
element. I just want to do the same persister.read(MyDocClass) with the
same MyDocClass in both cases.

Thanks for an awesome XML lib, it rocks.
