Question

我正在使用Java 6和最新版本的Xerces。我正在尝试解析一个像这样开始的HTML文档......

<!DOCTYPE html>

以后引用实体“＆amp; raquo”。解析死亡除了......

org.xml.sax.SAXParseException: The entity "raquo" was referenced, but not declared.

有没有办法告诉解析器忽略它无法解决的这些类型的实体？如果没有，我有什么解析器插件？

编辑：这是我解析HTML的方式，实际上是XHTML。我在尝试下面之前通过JSoup传递String来清理它......

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setValidating(false);
    factory.setExpandEntityReferences(false);
    final DocumentBuilder builder = factory.newDocumentBuilder();
    final InputSource s = new InputSource(new StringReader(str));
    org.w3c.dom.Document result = builder.parse(s);

从 1.10.3 版本开始，JSoup提供W3CDom帮助程序类，允许您将org.jsoup.nodes.Document直接转换为org.w3c.dom.Document。

考虑以下示例：

String str =
        "<!DOCTYPE html>" +
        "<html>" +
        "<dody>" +
        "<div>&raquo; example</div>" +
        "</dody>" +
        "</html>";

Document document = Jsoup.parse(str);
W3CDom w3cDom = new W3CDom();
org.w3c.dom.Document result = w3cDom.fromJsoup(document);

它忽略实体引用解析的方式？
