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();
}
}
解决方法
如果你的代码没有正确复制文件,我猜你有一个字符编码问题.由于XML的默认编码是UTF-8,而FileReader的默认编码是您平台的默认编码,我建议改为：
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"
)
);
XML解析器将为您提供元素(或元素事件),而不是行.例如,他们无法区分空白区域的变化：
<tag attr1="val1" attr2="val2" />
与：
<tag attr1="val1"
attr2="val2"
/>
