下面是三个java例子，关于读取wps/et/dps的方法

1.读取wps（读取文本）: 通过流加载wps文件，读取文字内容

import com.spire.doc.*;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.IOException;

public class ReadTextFromWPS {
public static void main(String[] args) throws IOException{
//通过流加载WPS文字文档
FileInputStream inputStream = new FileInputStream(new File("test.wps"));
Document doc = new Document();
doc.loadFromStream(inputStream, FileFormat.Doc);

//获取文本保存为String
String text = doc.getText();

//将String写入Txt
writeStringToTxt(text,"读取WPS文本.txt");
}
public static void writeStringToTxt(String content, String txtFileName) throws IOException {

FileWriter fWriter= new FileWriter(txtFileName,true);
try {
fWriter.write(content);
}catch(IOException ex){
ex.printStackTrace();
}finally{
try{
fWriter.flush();
fWriter.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
}

2. 读取et：直接加载et格式的表格文件，读取数据

import com.spire.xls.*;

public class ExcelToText {
public static void main(String[] args) {
//加载et格式的表格文件
Workbook workbook = new Workbook();
workbook.loadFromFile("test.et");

//获取工作表
Worksheet sheet = workbook.getWorksheets().get(0);

//获取指定单元格中的文本数据
CellRange range = sheet.getCellRange("A1");
String text = range.getText().trim();
System.out.println(text);
}
}

3.读取dps：直接加载dps格式的幻灯片文档，读取文本

import com.spire.presentation.IAutoShape;
import com.spire.presentation.ISlide;
import com.spire.presentation.ParagraphEx;
import com.spire.presentation.Presentation;
import java.io.FileWriter;

public class ExtractText {
public static void main(String[]args) throws Exception{
//加载测试文档
Presentation ppt = new Presentation();
//ppt.loadFromFile("test.pptx");
ppt.loadFromFile("test.dps");

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());
}
}
}
}
//保存到文本文件
FileWriter writer = new FileWriter("ExtractTextfromDPS.txt");
writer.write(buffer.toString());
writer.flush();
writer.close();
}
}
