.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
An object of this class represents a chunk of \s-1XML\s0 content, the kind
of matter that can be contained within an \s-1XML\s0 element.  This is in an
abstract form, intended for general manipulation.  It is completely
isolated from the textual representation of \s-1XML\s0, 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.
.PP
An \s-1XML\s0 content chunk consists of a sequence of zero or more characters
and \s-1XML\s0 elements, interspersed in any fashion.  Character content can
use almost all Unicode characters, with only a few characters (such as
most of the \s-1ASCII\s0 control characters) prohibited by the specification
from being directly represented in \s-1XML\s0.  Each \s-1XML\s0 element in a content
chunk itself recursively contains a chunk of content, in addition to
having attached metadata.
.PP
This class is not meant to be subclassed.  \s-1XML\s0 content is unextendable,
dumb data.  Content objects are better processed using the functions in
XML::Easy::NodeBasics than using the methods of this class.
.SH "CONSTRUCTOR"
.IX Header "CONSTRUCTOR"
.IP "XML::Easy::Content\->new(\s-1TWINE\s0)" 4
.IX Item "XML::Easy::Content->new(TWINE)"
Constructs and returns a new content chunk object with the specified
content.
\&\fI\s-1TWINE\s0\fR must be a reference to an array listing the chunk's
content in twine form (see \*(L"Twine\*(R" in XML::Easy::NodeBasics).
The content is checked for validity, against the \s-1XML\s0 1.0
specification, and the function \f(CW\*(C`die\*(C'\fRs if it is invalid.
.SH "METHODS"
.IX Header "METHODS"
.ie n .IP "$content\->twine" 4
.el .IP "\f(CW$content\fR\->twine" 4
.IX Item "$content->twine"
Returns a reference to an array listing the chunk's
content in twine form (see \*(L"Twine\*(R" in XML::Easy::NodeBasics).
.Sp
The returned array must not be subsequently modified.  If possible,
it will be marked as read-only in order to prevent modification.
.ie n .IP "$content\->content" 4
.el .IP "\f(CW$content\fR\->content" 4
.IX Item "$content->content"
Deprecated alias for the \*(L"twine\*(R" method.
