       This module implements a bare-bones class specifically for the purpose of capturing data from the
       XML::Writer module.  XML::Writer expects an IO::Handle object and writes XML data to the specified object
       (or STDOUT) via it's print() method.  This module simulates such an object for the specific purpose of
       providing the required print() method.

       It is recommended that $writer->end() is called prior to calling $s->value() to check for well-
       formedness.

       XML::Writer::String provides three methods, "new()", "print()" and "value()":

       "$s = XML::Writer::String-"new([list]);>
           new() returns a new String handle.

       "$count = $s-"print([list]);>
           print() appends concatenated list data and returns number of items in list.

       "$val = $s-"value([list]);>
           value()  returns  the  current  content  of  the  object  as  a  scalar.   It  can  also  be  used to
           initialize/overwrite the current content with concatenated list data.

       XML::Writer::String - Capture output from XML::Writer.

       This module is designed for the specific purpose of capturing  the  output  of  XML::Writer  objects,  as
       described  in  this  document.  It does not inherit form IO::Handle.  For an alternative solution look at
       IO::Scalar, IO::Lines, IO::String or Tie::Handle::Scalar.
