Boolean SXmlReader::AtEnd ( )

slot

Returns true if the reader has read until the end of the XML document, or if an Error() has occurred and reading has been aborted. Otherwise, it returns false.

Attributes

Array SXmlReader::Attributes ( )

slot

Returns the attributes of a StartElement.

DocumentEncoding

String SXmlReader::DocumentEncoding ( )

slot

If the TokenType() is StartDocument, this function returns the encoding string as specified in the XML declaration. Otherwise an empty string is returned.

String SXmlReader::DocumentVersion ( )

slot

If the TokenType() is StartDocument, this function returns the version string as specified in the XML declaration. Otherwise an empty string is returned.

Error

ErrorEnum SXmlReader::Error ( )

slot

Returns the type of the current error, or NoError if no error occurred.

HasError

Boolean SXmlReader::HasError ( )

slot

Returns true if an error has occurred, otherwise false.

IsStandaloneDocument

Boolean SXmlReader::IsStandaloneDocument ( )

slot
