我正在使用 Java 6 并尝试解析以

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

我下载了实体 DTD,“http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd”,并将它放在我的类路径中。但是,当我尝试使用(注意使用自定义实体解析器)解析文档时......

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setValidating(false);
    factory.setExpandEntityReferences(false);
    final DocumentBuilder builder = factory.newDocumentBuilder();
    builder.setEntityResolver(new EntityResolver() {
        @Override
        public InputSource resolveEntity(String publicId, String systemId) {
            InputSource inputSource = null;
            try {
                final String resource = systemId.substring(systemId.lastIndexOf("/") + 1);
                final InputStream inputStream = getClass().getClassLoader().getResourceAsStream(resource);
                inputSource = new InputSource(inputStream);
            } catch (Exception e) {
                // No action; just let the null InputSource pass through
            }
            return inputSource;
        }
    });
    final InputSource s = new InputSource(new StringReader(str));
    org.w3c.dom.Document result = builder.parse(s);

我在“builder.parse(s)”行上得到以下异常。我怎样才能毫无例外地解析文档,或者至少我怎样才能弄清楚这个东西在抱怨什么 URL?

检查“资源”的值是什么,并确保它指向本地机器中的正确文件。
