[Htmlparser-user] Recreating HTML

[<dha...@or...>]

Hi,
=A0
I would like to know the purpose of the toHTML() function in HTMLTag
class. Is this function supposed to output the parsed tag as parsed by
the HTMLParser or am I supposed to override this function in my custom
tag class to depict theHTML formed if any of the attributes of the tag
have been changed. In short I woudl like to know whether I need to
override this method since at present I can only see the original parsed
data in it and not my modified data.

If this is true, then we must ensure that all tag writers need to
override this function as per their individual tags.

   Hi Dhaval
   About the checked issue, I believe the parser will not throw an error
   in
   such a situation if checked is given in an INPUT tag.
  =20
   Right - but it does not give u the field as well.

   While registering scanners with the HTML parser I will need to create
   an
   instance of my scanner and supply a filter string. What are these
   filter
   strings and what should I use?
  =20
   You can ignore the filter string, its for the command line parser
   testing.

      Hi,

      I am writing a scanner. The constructor for a scanner contains a
      parameter for a filter.
      While registering scanners with the HTML parser I will need to
      create an
      instance of my scanner and supply a filter string. What are these

Hi Dhaval,
I would like to know the purpose of the toHTML() function in HTMLTag
class. Is this function supposed to output the parsed tag as parsed by
the HTMLParser or am I supposed to override this function in my custom
tag class to depict theHTML formed if any of the attributes of the tag

This method is supposed to give you a reconstruction of the HTML Tag =
parsed. Even if the tag parsed was malformed, the result of this method =
will be correct HTML.

In short I woudl like to know whether I need to
override this method since at present I can only see the original parsed
data in it and not my modified data.

Thats right - for your application - you will need to change the =
functionality of this method.
I've been thinking of introducing HTMLRenderers, for a tag - so you can =
dynamically change it for the tags that you want. That would be a =
cleaner solution - so you might have an interface

public interface HTMLRenderer {
    public String toHTML() {
    }
}

and for your input tag, you should have a static method
public static void addHTMLRenderer(HTMLRenderer renderer) {
}

Then, HTMLInputTag.toHTML() may have an implementation -=20
public String toHTML() {
     if (renderer!=3Dnull) return renderer.toHTML(); else=20
        return super.toHTML();
}

This way, we can have both the normal functionality, and the modified =
functionality.
