这篇文章将介绍如何使用spire.presentation for java提取powerpoint文档中的文本。

源文档：

import com.spire.presentation.*;
import java.io.filewriter;
public class extracttext {
    public static void main(string[] args) throws exception {
        //创建presentation实例
        presentation ppt = new presentation();
        //加载powerpoint文档
        ppt.loadfromfile("input.pptx");
        stringbuilder buffer = new stringbuilder();
        //遍历文档中的幻灯片，提取文本
        for (object slide : ppt.getslides()) {
            for (object shape : ((islide) slide).getshapes()) {
                if (shape instanceof iautoshape) {
                    for (object tp : ((iautoshape) shape).gettextframe().getparagraphs()) {
                        buffer.append(((paragraphex) tp).gettext());
                    }
                }
            }
        }
        //保存文本到文本文件
        filewriter writer = new filewriter("extracttext.txt");
        writer.write(buffer.tostring());
        writer.flush();
        writer.close();
    }
}
