NAME

       XML::Easy::Content - abstract form of XML content

SYNOPSIS

               use XML::Easy::Content;

               $content = XML::Easy::Content->new([
                       "foo",
                       $subelement,
                       "bar",
               ]);

               $twine = $content->twine;

DESCRIPTION

       An object of this class represents a chunk of XML content, the kind of
       matter that can be contained within an XML element.  This is in an
       abstract form, intended for general manipulation.  It is completely
       isolated from the textual representation of XML, and holds only the
       meaningful content of the chunk.  The data in a content object cannot
       be modified: different data requires the creation of a new object.

       An XML content chunk consists of a sequence of zero or more characters
       and XML elements, interspersed in any fashion.  Character content can
       use almost all Unicode characters, with only a few characters (such as
       most of the ASCII control characters) prohibited by the specification
       from being directly represented in XML.  Each XML element in a content
       chunk itself recursively contains a chunk of content, in addition to
       having attached metadata.

       This class is not meant to be subclassed.  XML content is unextendable,
       dumb data.  Content objects are better processed using the functions in
       XML::Easy::NodeBasics than using the methods of this class.

CONSTRUCTOR

       XML::Easy::Content->new(TWINE)
           Constructs and returns a new content chunk object with the
           specified content.  TWINE must be a reference to an array listing
           the chunk's content in twine form (see "Twine" in
           XML::Easy::NodeBasics).  The content is checked for validity,
           against the XML 1.0 specification, and the function "die"s if it is
           invalid.

METHODS

       $content->twine
           Returns a reference to an array listing the chunk's content in
           twine form (see "Twine" in XML::Easy::NodeBasics).

           The returned array must not be subsequently modified.  If possible,
           it will be marked as read-only in order to prevent modification.

       $content->content
           Deprecated alias for the "twine" method.
