Question

我使用SAXParser来解析包含俄语字符的XML。 XML看起来像这样：

   ...
   <exercise>
     <ID>2</ID>
     <training_types_id>1</training_types_id>
     <Name>Тройки</Name>
     <last_modified>0000-00-00 00:00:00</last_modified>
     <del_check>0</del_check>
   </exercise>
   ...

应用程序在此代码上崩溃（并在节点上联机＃34;名称＆＃34;其中包含俄语符号）：

String exerciseNameValue = exerciseNameElement.getFirstChild().getNodeValue();

服务器以这种方式编码数据：

        if (is_null($DOMDocument)) {
        $DOMDocument =new DOMDocument('1.0', 'UTF-8');
        $DOMDocument->formatOutput = true;
        $this->xml_encode($mixed, $DOMDocument, $DOMDocument);
        return $DOMDocument->saveXML();

我以这种方式收到数据：

HttpEntity entity = res.getEntity();
websiteData = EntityUtils.toString(entity, "UTF-8");

以这种方式解析：

    private static Document ParseXMLString(String xmlString) {

    // fix encoding problem
    xmlString = xmlString.replaceAll("[^\\x20-\\x7e]", "");

    DocumentBuilderFactory factory = javax.xml.parsers.DocumentBuilderFactory.newInstance();
    DocumentBuilder db;
    Document doc = null;

    try {
        InputSource inStream = new InputSource(); 
        inStream.setCharacterStream(new StringReader(xmlString));
        //inStream.setEncoding("UTF8");

        db = factory.newDocumentBuilder();
        doc = db.parse(inStream);

    } catch (SAXException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (ParserConfigurationException e) {
        e.printStackTrace();
    }

    return doc;
}
