【问题描述】：
我正在使用 Java 6。我想找到一个可以清理丑陋 HTML 的工具。具体来说，我想要一个可以处理以下问题的工具......
<script type="text/javascript">
document.write(
'<scr'+'ipt src="http://ox-d.journatic.com/w/1.0/jstag"><\/scr'+'ipt>');
</script>
我已经尝试过 JSoup v 1.6.2 来处理上述问题，但使用运行上述代码
final org.jsoup.nodes.Document doc = Jsoup.parse(html);
final String formattedHtml = doc.toString();
返回相同的代码。当我尝试用它解析时，上面的问题就很明显了
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
final DocumentBuilder builder = factory.newDocumentBuilder();
final InputSource s = new InputSource(new StringReader(cleanedUpHtml));
org.w3c.dom.Document result = builder.parse(s);
我得到了例外...
org.xml.sax.SAXParseException: Element type "scr" must be followed by either attribute specifications, ">" or "/>".

关于可以整理以上内容的 HTML 解析器有什么建议吗？ - 戴夫

这不是html...它是javascript，在您的示例中它是一个字符串作为函数参数。我认为不可能实现这样的目标。进一步上 sax 只能解析 xml 而不能解析 html。如果您不使用 xhtml（其中包括包装到
<![CDATA[...]]>部分中的所有 javascript），那么 sax 将无法解析该输入。
