java version "1.3beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3beta-O)
Java(TM) HotSpot Client VM (build 1.3beta-O, mixed mode)
When HTML input is parsed by the HTMLEditorKit, <FORM amd </FORM> tags are
ignored.
I discovered the bug when I wanted to use an iterator
HTMLDocument.Iterator formIterator=doc.getIterator(HTML.Tag.INPUT)
That iterator never returned a tag.
The test example demonstrates the bug by simply writing the document to a file.
However, it does not directly demonstrate the iterator problem, for which
I have not opened a separate bug.
The behaviour is the same in JDK1.2.2
Input HTML file input.htm:
<html>
<head>
<title>Test</title>
</head>
<body>
<form action="http://www.javasoft.com" method=get>
<input type="hidden" name="test" value="1">
</form>
</body>
</html>
Output HTML file output.htm:
<html>
<head>
<title>Test </title>
</head>
<body>
<input value="1" type="hidden" name="test">
<p>
</p>

kit.read(reader, doc, 0);

writer.close();

See below code:
/*
HTMLDocument.Iterator ignores tags e.g. <INPUT. I think <IMG is not working,
either.
It would be handy to have an easy way to iterate through the input tags
of e.g. the 2nd form on a page only. Similar to JavaScript
document.forms[1].elements[index] and document.forms[1].elements.length. I came
across this bug when I was looking for such functionality.
