PHP parsing invalid html

Question

i'm trying to parse some html that is not on my server

    $dom = new DOMDocument();
    $dom->loadHTMLfile("http://www.some-site.org/page.aspx");      
    echo    $dom->getElementById('his_id')->item(0);

but php returns an error something like ID his_id already defined in http://www.some-site.org/page.aspx, line: 33. I think that is because DOMDocument is dealing with invalid html. So, how can i parse it even though is invalid?

You should run HTML Tidy on it to clean it up before parsing it.

$html = file_get_contents('http://www.some-site.org/page.aspx');
$config = array(
  'clean' => 'yes',
  'output-html' => 'yes',
);
$tidy = tidy_parse_string($html, $config, 'utf8');
$tidy->cleanRepair();
$dom = new DOMDocument;
$dom->loadHTML($tidy);

See this list of options.

@kmunky why not? Without Tidy you're SOL, basically.

Duplicated id's, you'll have to fix them yourself (been there, done that).

Have a look at: libxml_use_internal_errors()

Reading the docs, I see a $dom->strictErrorChecking that defaults to TRUE. What happens if you set $dom->strictErrorChecking = false?
