您好，我有一个包含此 DTD 的 XML：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE cXML SYSTEM "http://xml.cXML.org/schemas/cXML/1.2.014/cXML.dtd">
在 Java(IBM) 中，我使用它来解析 xml：
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(true);
DocumentBuilder builder = factory.newDocumentBuilder();
InputSource is = new InputSource(new StringReader(xml));
domdoc = builder.parse(is);
但是当这个代理被执行时，我会在代码 builder.parse(is) 处收到一个错误。这是日志：

等等
但是当我添加这一行时：
factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
然后它工作......
问题：我可以使用 Java 中的 dtd 模式验证 xml，如果可以，如何验证？
