alert(form[i]);
}
}
</script>
</head>
<body>
<form id="form1">
<form id="form2">
</form>
<form id="form3">
</form>
<form id="form4">
</form>
</form>
<form id="form5">
</form>
<script>
vasculha("form1");
</script>
</body>
</html>

That's because something like this:
<form id="form1">
<form id="form2">
</form>
<form id="form3">
</form>
</form>
is constructed in Mozilla with the following DOM:
# FORM id="form1"
* #text:
# #text:
# FORM id="form3"
As you can see, <form> tags can't be nested currently in Mozilla (and #form2 seems completely 'forgotten').
In Opera9 it is possible now to nest <form> tags.
I suspect this is something that also will be possible with the whatwg parsing spec.

So the problem is that the parsing engine doesn't allow nesting form tags?
If it's true how we should do to make this kinda of relationship? Use hiden fields to say which form is the parent tags?

What does IE6 do?

> What does IE6 do?
IE6 has this as innerHTML:
<FORM id=form1><FORM id=form2></FORM>
<FORM id=form3></FORM></FORM></
The dom view looks like this:
FORM id="form1"
FORM id="form2"
FORM id="form3"
/FORM
As you can see, form3, is _not_ a child of form1.
Personally, I think what Opera9 is doing in this case, makes the most sense.

Since IE doesn't support this, I don't think this counts as a "major" bug, but fixing bug 136397 will make fixing this bug much easier.
