`filename` : | the filename
`encoding` : | a free form C string describing the SGML document encoding, or NULL
`sax` : | the SAX handler block

`filename` : | the filename
`encoding` : | the SGML document encoding, or NULL

### docbParseDocument ()

    int         docbParseDocument               (docbParserCtxtPtr ctxt);

parse an SGML document (and build a tree if using the standard SAX interface).
