Actually you should not. From an XML point of view the two are strictly equivalent. When I implemented the reader I found out that they distinguished the two and it made my life difficult, a parser is not supposed to expose the difference. If you have to rely on this, there is something broken. > For the short version, you'll get a XMLREADER_TYPE_ELEMENT. If you > call xmlReaderIsEmptyElement(), it will return 1.

Unless you use the reader on an existing preparsed tree and in which case libxml2 discards the information and the difference can't be provided.
