为什么我的DOM解析器不能读取UTF-8 [英] Why my DOM parser cant read UTF-8

问题描述

我有问题，我的DOM解析器无法在XML文件中有UTF-8字符时加载文件
现在，我知道我必须给他指令来读取utf-8，但是我不知道如何把它放在我的代码
中，它是：

 文件xmlFile = new File（fileName） ; 
 DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance（）; 
 DocumentBuilder dBuilder = dbFactory.newDocumentBuilder（）; 
文档doc = dBuilder.parse（xmlFile）; 
 doc.getDocumentElement（）。normalize（）; 
  

我知道有方法setencoding（），但我不知道在哪里放在我的代码中...

解决方案

为我工作

  InputStream inputStream = new FileInputStream（completeFileName）; 
读者阅读器=新的InputStreamReader（inputStream，UTF-8）; 
 InputSource is = new InputSource（reader）; 
 is.setEncoding（UTF-8）; 
 
 DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance（）; 
 DocumentBuilder dBuilder = dbFactory.newDocumentBuilder（）; 
文档doc = dBuilder.parse（is）; 
  

I have problem that my DOM parser can´t load file when there are UTF-8 characters in XML file Now, i am aware that i have to give him instruction to read utf-8, but i don´t know how to put it in my code here it is:

File xmlFile = new File(fileName);
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(xmlFile);
doc.getDocumentElement().normalize();

i am aware that there is method setencoding(), but i don´t know where to put it in my code...

解决方案

Try this. Worked for me

        InputStream inputStream= new FileInputStream(completeFileName);
        Reader reader = new InputStreamReader(inputStream,"UTF-8");
        InputSource is = new InputSource(reader);
        is.setEncoding("UTF-8");

        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(is);
