Description
Details
Macro HTML_COMMENT_NODE
#define HTML_COMMENT_NODE;
Macro. A comment in a HTML document is really implemented the same way as a comment in an XML document.
Macro HTML_ENTITY_REF_NODE
#define HTML_ENTITY_REF_NODE;
Macro. An entity reference in a HTML document is really implemented the same way as an entity reference in an XML document.
Macro HTML_PI_NODE
#define HTML_PI_NODE;
Macro. A processing instruction in a HTML document is really implemented the same way as a processing instruction in an XML document.
Macro HTML_PRESERVE_NODE
#define HTML_PRESERVE_NODE;
Macro. A preserved node in a HTML document is really implemented the same way as a CDATA section in an XML document.
Macro HTML_TEXT_NODE
#define HTML_TEXT_NODE;
Macro. A text node in a HTML document is really implemented the same way as a text node in an XML document.

htmlNewDocNoDtD ()
htmlDocPtr htmlNewDocNoDtD (const xmlChar * URI,
const xmlChar * ExternalID)
Creates a new HTML document without a DTD node if @URI and @ExternalID are NULL
