Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
DOM is meant to handle XML conforming data (not broken HTML). It's not
a
libxml bug either. The HTML load functionality take best guess at
trying
to fix developer tag soup.

Description:
------------
I'm trying to get a list of all the input elements of a form tag and
am having some difficulty doing so due to a PHP bug. First, here's my
XHTML:
<div>
<form action="">
<input type="text" name="a" />
</div>
<div>
<input type="text" name="b" />
</div>
<div>
<input type="submit" />
</form>
</div>
It isn't semantically correct XHTML but that doesn't stop web
developers from coding like that.
Anyway, in both Firefox and IE, if you visit a webpage containing the
above, and hit the Submit button, the resultant URL will have both a
and b defined via GET.
I'd like to be able to get a list of the same input parameters that
the browser does for a given form element. I had been using "//
form[1]//input" as an XPath query, but that doesn't work, here,
because not all of the inputs are children of the form element.
Indeed, if I use DOMDocument::saveHTML(), I get something more like
this:
<div>
<form action="">
<input type="text" name="a" />
</form>
</div>
<div>
<input type="text" name="b" />
</div>
<div>
<input type="submit" />
</div>
Before you go off and pass the buck to the libxml developers, without
even reviewing this, consider, first, that it might not be a bug in
libxml, but rather, with PHP's bindings to libxml.
Further, if you're going to be pass the buck, do so, yourself. I don't
know C or C++ or whatever language libxml was originally intended to be
used with. Since I don't know C / C++, if I were to file a bug report
with the libxml developers, it'd have to be in PHP, which they may or
may not know, themselves. As such, it wouldn't be a very useful bug
report, whereas if the person who implemented the libxml bindings for
PHP filed it, they could make it a whole lot more useful.
Maybe a good fix for PHP (that wouldn't involve the libxml people)
would be to use a different XML parsing engine. Maybe use the HTML
rendering engine that Firefox uses - Gecko.
