HTML Parsers in Java

Reference: HTML Parser 对于网页格式中的文本，提取其内容
Because need to parse HTML page to get some parameters of Java Applet tag.
The HTML Parser is a Java library. It support those tag below.

NodeFilter textFilter = new NodeClassFilter(TextNode.class);
NodeFilter linkFilter = new NodeClassFilter(LinkTag.class);
NodeFilter appletFilter = new NodeClassFilter(AppletTag.class);
NodeFilter imageFilter = new NodeClassFilter(ImageTag.class);
NodeFilter frameFilter = new NodeClassFilter(FrameTag.class);
NodeFilter scriptFilter = new NodeClassFilter(ScriptTag.class);
NodeFilter formFilter = new NodeClassFilter(FormTag.class);
NodeFilter objectFilter = new NodeClassFilter(ObjectTag.class);
NodeFilter remarkFilter = new NodeClassFilter(RemarkNode.class);
NodeFilter metaFilter = new NodeClassFilter(MetaTag.class);

The complete java code is:
