dom4j解析XML报错

List list = document.selectNodes("//article/@level" );

while(iter.hasNext()){

}
}
XMLWriter output = new XMLWriter(
new FileWriter( new File("D:/test/jsp/catalog/catalog-modified.xml") ));
output.write( document );
output.close();
}

catch(DocumentException e)
{
System.out.println(e.getMessage());
}
catch(IOException e){
System.out.println(e.getMessage());
}
}
public static void main(String[] argv){
Dom4JParser dom4jParser=new Dom4JParser();
dom4jParser.modifyDocument(new File("D:/test/jsp/catalog/catalog.xml"));
}
}


编译通过了，执行时报错
c Nested exception: c

请问哪里错了。

检查xml文件的格式，是否正确？

[guo624587253]

把你的xml文件贴出来看看

[Headsen]

代码鉴定无误！建议你监察一下XML文件

实在不行就调试吧！看看执行到哪一句抛得异常。

[jinchun1234]

xml文件中C标签有问题

[Java技术栈]

哪行出错了？？？ ？
