137 \& use XML::Atom::Entry;
138 \& my $entry = XML::Atom::Entry\->new;
139 \& $entry\->title(\*(AqMy Post\*(Aq);
140 \& $entry\->content(\*(AqThe content of my post.\*(Aq);
141 \& my $xml = $entry\->as_xml;

147 .ie n .SS "XML::Atom::Entry\->new([ $stream ])"
148 .el .SS "XML::Atom::Entry\->new([ \f(CW$stream\fP ])"
149 .IX Subsection "XML::Atom::Entry->new([ $stream ])"
150 Creates a new entry object, and if \fI\f(CI$stream\fI\fR is supplied, fills it with the
151 data specified by \fI\f(CI$stream\fI\fR.
153 Automatically handles autodiscovery if \fI\f(CI$stream\fI\fR is a \s-1URI\s0 (see below).
155 Returns the new \fIXML::Atom::Entry\fR object. On failure, returns \f(CW\*(C`undef\*(C'\fR.
157 \&\fI\f(CI$stream\fI\fR can be any one of the following:
159 Reference to a scalar
161 This is treated as the \s-1XML\s0 body of the entry.
165 This is treated as the name of a file containing the entry \s-1XML\s0.
169 This is treated as an open filehandle from which the entry \s-1XML\s0 can be read.
170 .ie n .SS "$entry\->content([ $content ])"
171 .el .SS "\f(CW$entry\fP\->content([ \f(CW$content\fP ])"
172 .IX Subsection "$entry->content([ $content ])"
173 Returns the content of the entry. If \fI\f(CI$content\fI\fR is given, sets the content
174 of the entry. Automatically handles all necessary escaping.
175 .ie n .SS "$entry\->author([ $author ])"
176 .el .SS "\f(CW$entry\fP\->author([ \f(CW$author\fP ])"
177 .IX Subsection "$entry->author([ $author ])"
178 Returns an \fIXML::Atom::Person\fR object representing the author of the entry,
179 or \f(CW\*(C`undef\*(C'\fR if there is no author information present.
181 If \fI\f(CI$author\fI\fR is supplied, it should be an \fIXML::Atom::Person\fR object
182 representing the author. For example:
185 \& my $author = XML::Atom::Person\->new;
186 \& $author\->name(\*(AqFoo Bar\*(Aq);
187 \& $author\->email(\*(Aqfoo@bar.com\*(Aq);
188 \& $entry\->author($author);
190 .ie n .SS "$entry\->link"
191 .el .SS "\f(CW$entry\fP\->link"
192 .IX Subsection "$entry->link"
193 If called in scalar context, returns an \fIXML::Atom::Link\fR object
194 corresponding to the first \fI<link>\fR tag found in the entry.
196 If called in list context, returns a list of \fIXML::Atom::Link\fR objects
197 corresponding to all of the \fI<link>\fR tags found in the entry.
198 .ie n .SS "$entry\->add_link($link)"
199 .el .SS "\f(CW$entry\fP\->add_link($link)"
200 .IX Subsection "$entry->add_link($link)"
201 Adds the link \fI\f(CI$link\fI\fR, which must be an \fIXML::Atom::Link\fR object, to
202 the entry as a new \fI<link>\fR tag. For example:
205 \& my $link = XML::Atom::Link\->new;
206 \& $link\->type(\*(Aqtext/html\*(Aq);
207 \& $link\->rel(\*(Aqalternate\*(Aq);
208 \& $link\->href(\*(Aqhttp://www.example.com/2003/12/post.html\*(Aq);
209 \& $entry\->add_link($link);
211 .ie n .SS "$entry\->get($ns, $element)"
212 .el .SS "\f(CW$entry\fP\->get($ns, \f(CW$element\fP)"
213 .IX Subsection "$entry->get($ns, $element)"
214 Given an \fIXML::Atom::Namespace\fR element \fI\f(CI$ns\fI\fR and an element name
215 \&\fI\f(CI$element\fI\fR, retrieves the value for the element in that namespace.
217 This is useful for retrieving the value of elements not in the main Atom
218 namespace, like categories. For example:
221 \& my $dc = XML::Atom::Namespace\->new(dc => \*(Aqhttp://purl.org/dc/elements/1.1/\*(Aq);
222 \& my $subj = $entry\->get($dc, \*(Aqsubject\*(Aq);
224 .ie n .SS "$entry\->getlist($ns, $element)"
225 .el .SS "\f(CW$entry\fP\->getlist($ns, \f(CW$element\fP)"
226 .IX Subsection "$entry->getlist($ns, $element)"
227 Just like \fI\f(CI$entry\fI\->get\fR, but if there are multiple instances of the
228 element \fI\f(CI$element\fI\fR in the namespace \fI\f(CI$ns\fI\fR, returns all of them. \fIget\fR
229 will return only the first.
