Java：将 StreamResult 保存到文件

使用 Java 编程语言，我们可以将 StreamResult 保存到文件中。StreamResult 是一个用于保存转换结果的类，我们可以使用它将 XML 数据保存到文件中。以下是一个示例代码，展示了如何将 StreamResult 保存到文件中。

java
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();

java
StreamResult result = new StreamResult(new File("output.xml"));

java
transformer.transform(source, result);

java
File outputFile = new File("output.xml");
if (outputFile.exists()) {
    System.out.println("XML data has been successfully saved to the file.");
} else {
    System.out.println("Failed to save XML data to the file.");
}

java
import java.io.File;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
public class StreamResultExample {
    public static void main(String[] args) {
        try {
            Source source = new StreamSource(new File("input.xml"));
            TransformerFactory transformerFactory = TransformerFactory.newInstance();
            Transformer transformer = transformerFactory.newTransformer();
            StreamResult result = new StreamResult(new File("output.xml"));
            transformer.transform(source, result);
            File outputFile = new File("output.xml");
            if (outputFile.exists()) {
                System.out.println("XML data has been successfully saved to the file.");
            } else {
                System.out.println("Failed to save XML data to the file.");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
