可以使用Apache POI库来操作Word文档,具体实现如下:
1. 加载Word文档
```java
FileInputStream fis = new FileInputStream("test.docx");
XWPFDocument document = new XWPFDocument(fis);
```
2. 获取文档中所有段落和表格,并遍历处理
```java
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (int i = paragraphs.size() - 1; i >= 0; i--) {
XWPFParagraph paragraph = paragraphs.get(i);
if (paragraph.getDocument().getPosOfParagraph(paragraph) > position) {
document.removeBodyElement(i);
}
}
List<XWPFTable> tables = document.getTables();
for (int i = tables.size() - 1; i >= 0; i--) {
XWPFTable table = tables.get(i);
if (table.getDocument().getPosOfTable(table) > position) {
document.removeBodyElement(i + paragraphs.size());
}
}
```
注:`position` 是指定位置,删除该位置之后的所有内容。
3. 保存修改后的文档
```java
FileOutputStream fos = new FileOutputStream("test.docx");
document.write(fos);
fos.close();
```
完整代码如下:
```java
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFTable;
public class DeleteContent {
public static void main(String[] args) throws IOException {
// 加载Word文档
FileInputStream fis = new FileInputStream("test.docx");
XWPFDocument document = new XWPFDocument(fis);
// 指定位置之后的所有内容都删除
int position = 5;
// 遍历所有段落和表格,删除指定位置之后的内容
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (int i = paragraphs.size() - 1; i >= 0; i--) {
XWPFParagraph paragraph = paragraphs.get(i);
if (paragraph.getDocument().getPosOfParagraph(paragraph) > position) {
document.removeBodyElement(i);
}
}
List<XWPFTable> tables = document.getTables();
for (int i = tables.size() - 1; i >= 0; i--) {
XWPFTable table = tables.get(i);
if (table.getDocument().getPosOfTable(table) > position) {
document.removeBodyElement(i + paragraphs.size());
}
}
// 保存修改后的文档
FileOutputStream fos = new FileOutputStream("test.docx");
document.write(fos);
fos.close();
}
}
```
