java使用POI读取potx文件

Question

我使用读取office03的方法来读取07的potx文件
代码如下
SlideShow ss = new SlideShow(new HSLFSlideShow(p));
// 得到源文件中的幻灯片数量
Slide[] slides = ss.getSlides();
for (int a = 0; a < slides.length; a++) {
// 为了取得幻灯片的文字内容，建立TextRun
TextRun[] tr = slides[a].getTextRuns();
for (int i = 0; i < tr.length; i++) {
// 将内容循环写入到txt文档中
new AddTxt().addtxt(path, pot, tr[i].getText(), true);
}

代码异常为
[color=red]org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF)

最好有具体代码

根据异常, 楼主采用的应该是 [url=http://poi.apache.org/apidocs/index.html]org.apache.poi.hslf[/url], 这个包只支持 PowerPoint 2007 以前的 ppt 文档解析. 因为 Office 2007 的文件底层实现方案(OOXML)和以前的版本(OLE2)有[url=http://poi.apache.org/]根本的变化[/url].
支持 2007 的包为: [url=http://poi.apache.org/apidocs/index.html]org.apache.poi.xslf[/url]
