7.11. Opt_Xml_Comment class

ConstructClass
ExtendsOpt_Xml_Cdata

The class represents the XML comments and provides an API to manipulate their contents. The class extends Opt_Xml_Cdata, so we can use the same manipulation methods, as in case of ordinary character data nodes.

Note that every XML node may become a comment by setting the node flag commented to true. Their contents, including the node itself, will be enclosed within <!-- and --> tags:

$node->set('commented', true);
