Question

I have opened an HTML file using

file_get_contents('http://www.example.com/file.html')

and want to parse the line including “ParseThis”:

 <h1 class=\"header\">ParseThis<\/h1>

As you can see, it’s within an h1 tag (the first h1 tag from the file). How can I get the text “ParseThis”?

Answer 1

You can use DOM for this.

// Load remote file, supress parse errors
libxml_use_internal_errors(TRUE);
$dom = new DOMDocument;
$dom->loadHTMLFile('http://www.example.com/file.html');
libxml_clear_errors();

// use XPath to find all nodes with a class attribute of header
$xp = new DOMXpath($dom);
$nodes = $xp->query('//h1[@class="header"]');

// output first item's content
echo $nodes->item(0)->nodeValue;
