请大家谈谈怎样把UTF-8的XML文件读成流,再改变后输出?

Question

org.w3c.dom.Document doc = javax.xml.parsers.DocumentBuilderFactory.newInstance().newDocumentBuilder().
                               parse(new org.xml.sax.InputSource(new InputStreamReader(new FileInputStream("C:/Temp/test.xml"),"UTF-8")));    javax.xml.transform.TransformerFactory.newInstance().newTransformer().transform(
        new javax.xml.transform.dom.DOMSource(doc),
        new javax.xml.transform.stream.StreamResult(new FileOutputStream("C:/temp/Result.xml")));

}


}
这是我写的,用的是现在最高版的jar包.
我看了一下资料,老版的jar包不能单独完成这样的工作,得与别的jar包合作完成,在这方面那位有经验,请说一说.

看看xml的书啊，在parse方面啊！还有节点，我也在努力！

Answer 3

你在parse里面改成
new org.xml.sax.InputSource(new InputStreamReader(new FileInputStream("G:\\workbackup\\tools\\ppadmin\\mult.xml"),"UTF-8")));

Answer 4

new org.xml.sax.InputSource(new InputStreamReader(new FileInputStream("G:\\workbackup\\tools\\ppadmin\\mult.xml"),"UTF-8")));

Answer 5

使用jdom吧，你能想到的xml操作他都有了。而且它使用标准接口，不管你的底层是
sax 还是 dom
