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.
