Reading property sets from Office 2007+ documents using java poi

Question

I tried reading property sets from Office 2007+ documents (docx, xlsx). Found an amazing solution at http://poi.apache.org/hpsf/how-to.html . There is an example for Office 2003 and early format (doc, xls, without "x").

public class ReadSummaryInformation {
    public static void main(final String[] args) throws IOException {
        final String filename = "C://file.docx";
        POIFSReader r = new POIFSReader();
        r.registerListener(new MyPOIFSReaderListener(),
                           "\005SummaryInformation");
        r.read(new FileInputStream(filename));
    }

    static class MyPOIFSReaderListener implements POIFSReaderListener {
        public void processPOIFSReaderEvent(final POIFSReaderEvent event)
        {
            SummaryInformation si = null;
            try {
                si = (SummaryInformation)
                    PropertySetFactory.create(event.getStream());
            }
            catch (Exception ex){
                throw new RuntimeException
                    ("Property set stream \"" +
                     event.getPath() + event.getName() + "\": " + ex);
            }
            final String title = si.getTitle();
            if (title != null)
                System.out.println("Title: \"" + title + "\"");
            else
                System.out.println("Document has no title.");
        }
    }
}

I tried to open docx and xlsx (which means that I was trying to read "\ 005SummaryInformation" from the docs) using this code, and guess what? I got an exception:

Exception in thread "main" org.apache.poi.poifs.filesystem.OfficeXmlFileException: 
The supplied data appears to be in the Office 2007+ XML. [b]You are calling the part
of POI that deals with OLE2 Office Documents.[/b] You need to call a different part of 
POI to process this data (eg XSSF instead of HSSF)

Mister http://poi.apache.org/ says loudly and clearly that:

Office OpenXML Format - XML-, Microsoft Office 2007 2008. XLSX, DOCX PPTX. API Open Packaging , openxml4j.

poi api, , HPSF PropertySet, , , , XSSF . , .

: "\ 005SummaryInformation" Office 2007+ POI? , api , Office 2007.
