I'm trying to parse some html that is inside an external .dat file.

I would normaly use the follwing code:

$html = new DOMDocument();
$html->loadHTMLFile('http://www.bvl.com.pe/includes/cotizaciones_todas.dat');
$xpath = new DOMXPath($html);
$path = '/somepath';
$nodelist = $xpath->query($path);
echo $nodelist->item(0)->nodeValue;

But I'm getting this error:

DOMDocument::loadHTMLFile(): htmlParseEntityRef: expecting ';' in http://www.bvl.com.pe/includes/cotizaciones_todas.dat, line: 15

I know that the problem is the loadHTMLFile, I tried using load or loadXML but it's not working neither. Any help would be appriciated.

UPDATE

To solve the problem I had to handle the errors using libxml_use_internal_errors(TRUE). Now I've a new problem, I want to count how many <tr> tags are inside the table. I'm using the following code:

$html = new DOMDocument();
libxml_use_internal_errors(TRUE);
$html->loadHTMLFile('http://www.bvl.com.pe/includes/cotizaciones_todas.dat');
libxml_clear_errors();
$xpath = new DOMXPath($html);
$tbody = $html->getElementsByTagName('tbody')->item(0);
$path = 'count(tr)';
$trCount = $xpath->evaluate($path,$tbody);

But I'm getting this error msg: PHP Catchable fatal error: Argument 2 passed to DOMXPath::evaluate() must be an instance of DOMNode, null given I already used the same code with other files and everything worked fine, but in this case it's not working, maybe because the html is broken?

    Look at your server's error log. it'll have more details about the 500. – Marc B Dec 09 '12 at 00:23

  • The html output is not valid (927 Errors, 1167 warning(s) according to http://validator.w3.org/check), check the top voted answer:http://stackoverflow.com/questions/3893375/how-can-i-scrape-a-website-with-invalid-html – AaronSantos Dec 09 '12 at 00:59
  • @AaronSantos you were right, the HTML was broken. However I've anew problem now (see update). – mat Dec 09 '12 at 01:36
