如何使用 Java 和 Xerces 解析符合 1.1 规范的 XML?

I'm using a DocumentBuilder to parse the XML (something like this):

public Element parseString(String xmlString) {
    try {
          DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
          DocumentBuilder documentBuilder = dbf.newDocumentBuilder();

          InputSource source = new InputSource(new StringReader(xmlString));

      // Throws org.xml.sax.SAXParseException becuase of the invalid character refs
          Document doc = documentBuilder.parse(source);

          return doc.getDocumentElement();

    } catch (ParserConfigurationException pce) {
          // Handle the error
    } catch (SAXException se) {
          // Handle the error
    } catch (IOException ioe) {
          // Handle the error
    }
}

我已尝试设置 XML 标头以指示 XML 符合 1.1 规范...

xmlString = "<?xml version="1.1" encoding="UTF-8" ?>" + xmlString;
