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.
