xml读取异常Invalid byte 1 of 1-byte UTF-8 sequence

 

说简单点当你解析别人的xml格式出现这个错误可能就是别人在生成xml时没有保存为utf-8的字符编码格式。

在中文版的window下java的默认的编码为GBK，也就是所虽然我们标识了要将xml保存为utf-8格式但实际上文件是以GBK格式来保存的，所以这也就是为什么能够我们使用GBK、GB2312编码来生成xml文件能正确的被解析，而以UTF-8格式生成的文件不能被xml解析器所解析的原因。

 

xml解析时遇到的编码异常：

解决：

 

1、最简单就是把<?xml version="1.0" encoding="UTF-8"?>改成<?xml version="1.0" encoding="gbk"?>

2、或者把xml打开另存的时候把字符集改为UTF-8后保存

3、在代码解析的时候先把xml重新写一遍

 

[javascript]
  1. SAXReader reader = new SAXReader();    
  2.  org.dom4j.Document document = reader.read("D:\\ha.xml");    
  3.  OutputFormat of = new OutputFormat();    
  4.  of.setEncoding("UTF-8"); //改变编码方式     
  5.  XMLWriter writer = new XMLWriter(new FileWriter "d:\\dom4j.xml"), of);    
SAXReader reader = new SAXReader();    org.dom4j.Document document = reader.read("D:\\ha.xml");    OutputFormat of = new OutputFormat();    of.setEncoding("UTF-8"); //改变编码方式    XMLWriter writer = new XMLWriter(new FileWriter "d:\\dom4j.xml"), of);

4、直接dom4j读取的时候用io来读，修改字符编码

 

[java]
  1. FileInputStream in = new FileInputStream(new File(fileName));  
  2. Reader read = new InputStreamReader(in,"gbk");  
  3. Document document = reader.read(read);
