PHP retrieve inner HTML as string from URL using DOMDocument [duplicate] - php

How to get innerHTML of DOMNode?

Closed 9 years ago.
I've been picking bits and pieces of code, you can see roughly what I'm trying to do, obviously this doesn't work and is utterly wrong:
<?php
$dom= new DOMDocument();
$dom->loadHTMLFile('http://example.com/');
$data = $dom->getElementById("profile_section_container");
$html = $data->saveHTML();
echo $html;
?>
Using a CURL call, I am able to retrieve the document URL source:
function curl_get_file_contents($URL)
{
$c = curl_init();
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_URL, $URL);
$contents = curl_exec($c);
curl_close($c);
if ($contents) return $contents;
else return FALSE;
}
$f = curl_get_file_contents('http://example.com/');
echo $f;
So how can I use this now to instantiate a DOMDocument object in PHP and extract a node using getElementById

Answer 1

This is the code you will need to avoid any malformed HTML errors:
$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTMLFile('http://example.com/');
$data = $dom->getElementById("banner");
echo $data->nodeValue."\n"
To dump whole HTML source you can call:
echo $dom->saveHTML();

Answer 2

<?php
$f = curl_get_file_contents('http://example.com/')
$dom = new DOMDocument();
#$dom->loadHTML($f);
$data = $dom->getElementById("profile_section_container");
$html = $dom->saveHTML($data);
echo $html;
?>
It would help if you provided the example html.

Answer 3

i'm not sure but i remember once i wanted to use this i was unbale to load some external url as file because the php.ini directve allow-url-fopen was set to off ...
So check your pnp.ini or try to open url with fopen to see if you can read the url as a file
<?php
$f = file_get_contents(url);
var_dump($f); // just to see the content
?>

Try this:
$dom= new DOMDocument();
$dom->loadHTMLFile('http://example.com/');
$data = $dom->getElementById("profile_section_container")->item(0);
$html = $data->saveHTML();
echo $html;

Answer 5

i think that now you can use DOMDocument::loadHTML
Maybe you should try Doctype existence (with a regexp) and then add it if necessary, for being sure to have it declare ...
