Parse out the contents of meta tag using HTML.Tag

Question

I need help with using the HTML.Tag class. I don't even know where to start...
I want to make a method that allows me to pass in a very long string and the NAME of the meta tag.. and will return the contents of the meta tag.. any help will be super..
sorry i do not have much of a code base to start with.. I am just guessing on how to get this to work..
private String getMetatag(String content,String Metaname)
String Metacontents;
Object HTML.Tag.META;
Object HTML.Attribute.NAME.Metaname;
     Object HTML.Attribute.CONTENT;
return Metacontents;
}

Answer 1

One of the way to get started is to check out how to overide (extend) the class
HTMLEditorKit.ParserCallback.. Lets say the class is called class A
Overide the methods for
HandleSImpleTags( HTML.Tag t, AttributeSet attribute, int pos) { }
roughly, the implemenation in that method is like this:
HandleSImpleTags( HTML.Tag t, AttributeSet attribute, int pos) {
if(t.equals(HTML.Tag.META) {
/// your procedure, what to do when encounter META tag
// String str = (String) attribute.getAttribute(HTML.Attribute.NAME);
// System.out.println(str);
You would still need to find some detail examples on how to use class A .
Roughly it is,
parser.parse(inputstream, an_instance of_class_A, true); // method in a outer class like a main class
parser is a instatiation of from the method getParser. This method need to be overidden as well.
