本文介绍如何使用Spire.Doc for Java来读取Word表格中的文本数据和图片。
用于测试的Word文档如下:
import com.spire.doc.*;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.DocPicture;
import com.spire.doc.interfaces.ITable;
import javax.imageio.ImageIO;
import java.awt.image.RenderedImage;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
public class GetTable {
public static void main(String[] args)throws IOException {
//加载Word测试文档
Document doc = new Document();
doc.loadFromFile("inputfile.docx");
//获取第一节
Section section = doc.getSections().get(0);
//获取第一个表格
ITable table = section.getTables().get(0);
//创建txt文件(用于写入表格中提取的文本)
String output = "ReadTextFromTable.txt";
File textfile = new File(output);
if (textfile.exists())
{
textfile.delete();
}
textfile.createNewFile();
FileWriter fw = new FileWriter(textfile, true);
BufferedWriter bw = new BufferedWriter(fw);
//创建List
List images = new ArrayList();
//遍历表格中的行
for (int i = 0; i < table.getRows().getCount(); i++)
{
TableRow row = table.getRows().get(i);
//遍历每行中的单元格
for (int j = 0; j < row.getCells().getCount(); j++)
{
TableCell cell = row.getCells().get(j);
//遍历单元格中的段落
for (int k = 0; k < cell.getParagraphs().getCount(); k++)
{
Paragraph paragraph = cell.getParagraphs().get(k);
bw.write(paragraph.getText() + "\t");//获取文本内容
//遍历段落中的所有子对象
for (int x = 0; x < paragraph.getChildObjects().getCount(); x++)
{
Object object = paragraph.getChildObjects().get(x);
//判定对象是否为图片
if (object instanceof DocPicture)
{
//获取图片
DocPicture picture = (DocPicture) object;
images.add(picture.getImage());
}
}
}
}
bw.write("\r\n");//写入内容到txt文件
}
bw.flush();
bw.close();
fw.close();
//将图片以PNG文件格式保存
for (int z = 0; z < images.size(); z++)
{
File imagefile = new File(String.format("提取的表格图片-%d.png", z));
ImageIO.write((RenderedImage) images.get(z), "PNG", imagefile);
}
}
}
