Derrick, the same problem then exists with the FormTag. Even if Input
tag is registered explicitly (as well as inside the FormScanner), tags
of type InputTag are not retrieved. I'll file a bug report for the same.
Related to the string filters I also have one issue. Ideally there
should be a contract for all the constructors of children of Tag class.
Currently we see different types of constructors in the different tags.
When I started out using the HTMLParser, this string filter totally
confused me. I was gicing some random input, I did'nt know y, did'nt
know where it was used and did'nt really see any benefit. Hence I
bel;ieve the no-arg constructor is a must for easy usage in all Tags.

Subject: Re: [Htmlparser-developer] Registering of scanners
You should get back explicit tags (not generic org.htmlparser.tags.Tag
objects) for each scanner you register.
If not, it's a bug.
On another topic, I have noticed a problem with string filters.
Scanners register with a filter string like:
parser.addScanner(new InputTagScanner("-i"));
or
addScanner(linkScanner.createImageScanner(ImageTag.IMAGE_TAG_FILTER));
By the way, both of these are "-i".
Since the filters are compared with == rather than a string comparison,
you would have to get the filter from the scanner itself for collectInto
to work:
x = new InputTagScanner("-i");
parser.addScanner(x);
...
div.collectInto(nodeList,x.getFilter());
It looks like collectInto(NodeList, String) needs fixing and
collectInto(NodeList, Class) is the way to go.
Maybe we should deprecate the former.
