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

URI:URI for the dtd, or NULL
ExternalID:the external ID of the DTD, or NULL
