复制XML文件以写入Java中的新XML文件

我想知道是否有人知道是否可以使用 Java中的一个XML解析器逐行读取XML文档中的每一行,并基本上在另一个XML文件中重现相同的文档？ (在我的例子中,只取出文档中从点X到点Y的行并复制它们).我考虑过在小型试运行中使用bufferedreader和bufferedwriter,但它没有完全正确地输出文件.以下是我在试运行中所做的事情,但这不是我想要的.那么有没有人有这方面的经验或有任何想法或建议提供？先感谢您.

JAVA CODE

public class IPDriver 
{
    public static void main(String[] args) throws IOException
    {
        BufferedReader reader = new BufferedReader(new FileReader("C:/Documents and Settings/user/workspace/Intern Project/Proposals/Converted Proposals/Extracted Items/ProposalOne/word/document.xml"));
        BufferedWriter writer = new BufferedWriter(new FileWriter("C:/Documents and Settings/user/workspace/Intern Project/Proposals/Converted Proposals/Extracted Items/ProposalOne/word/tempdocument.xml"));

        String line = null;

        while ((line = reader.readLine()) != null)
        {
            writer.write(line);
        }

        // Close to unlock.
        reader.close();
        // Close to unlock and flush to disk.
        writer.close();
    }
}

使用Ted Hopp工作JAVA代码

public class IPDriver 
    {
        public static void main(String[] args) throws IOException
        {
            BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream("C:/Documents and Settings/user/workspace/Intern Project/Proposals/Converted Proposals/Extracted Items/ProposalOne/word/document.xml"),"UTF-8"));
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("C:/Documents and Settings/user/workspace/Intern Project/Proposals/Converted Proposals/Extracted Items/ProposalOne/word/tempdocument.xml"),"UTF-8"));

            String line = null;

            while ((line = reader.readLine()) != null)
            {
                writer.write(line);
            }

            // Close to unlock.
            reader.close();
            // Close to unlock and flush to disk.
            writer.close();
        }
    }

BufferedReader reader = new BufferedReader(
    new InputStreamReader(
        new FileInputStream("...input file path..."),"UTF-8"
    )
);
BufferedWriter writer = new BufferedWriter(
    new OutputStreamWriter(
        new FileOutputStream("...output file path..."),"UTF-8"
    )
);
