Fetch the attributes using PHP crawler - php

Question

I am trying to fetch the name,address and location from crawling of a website . Its a single page and dont want any other thing other than this. I am using the below code.
<?php
include 'simple_html_dom.php';
$html = "http://www.phunwa.com/phone/0191/2604233";
$dom = new DomDocument();
$dom->loadHtml($html);
$xpath = new DomXpath($dom);
$div = $xpath->query('//*[#class="address-tags"]')->item(0);
for($i=0; $i < $div->length; $i++ )
{
print "nodename=".$div->item( $i )->nodeName;
print "\t";
print "nodevalue : ".$div->item( $i )->nodeValue;
print "\r\n";
echo $link->getElementsByTagName("<p>");
}
?>
The website html source code is
<div class="address-tags">
<p><strong>Name:</strong> RAJ GOPAL SINGH</p>
<p><strong>Address:</strong> R/O BARNAI NETARKOTHIAN, P.O.MUTHI TEH.& DISTT.JAMMU,X, 181206</p>
<p><strong>Location:</strong> JAMMU, Jammu & Kashmir, India</p>

Can somone please help me get the three attributes as output. Nothing is echop on the page as of now.
Thanks alot .

Answer 1

you need $dom->load($html); instead of $dom->loadHtml($html);. After doing this you wil; find your html is not well formed, so $xpath stay empty.
Maybe try something like:
$html = file_get_contents('http://www.phunwa.com/phone/0191/2604233');
$name = preg_replace('/(.*)(<p><strong>Name:<\/strong> )([^<]+)(<\/p>)(.*)/mis','$3',$html);
$address = preg_replace('/(.*)(<p><strong>Address:<\/strong> )([^<]+)(<\/p>)(.*)/mis','$3',$html);
$location = preg_replace('/(.*)(<p><strong>Location:<\/strong> )([^<]+)(<\/p>)(.*)/mis','$3',$html);
$othernumbers = preg_replace('/(.*)(<p><strong>Other Numbers:<\/strong> )(.*)/mis','$3',$html);
list($othernumbers,$trash)= preg_split('/<\/p>/mis',$othernumbers,0);
echo 'name: '.$name.'<br>address: '.$address.'<br>location: '.$location.'<br>other numbers: '.$othernumbers;
exit;

Answer 2

You should use the following for your XPath query:
//*[#class='address-tags']/p
so you're retrieving the actual paragraph nodes that are children of the 'address-tags' parent. Then you can use a loop on them:
$nodes = $xpath->query('//*[#class="address-tags"]/p');
for ($i = 0; $i < $nodes->length; $i++) {
echo $nodes->item($i)->nodeValue;
}
// or just
foreach($nodes as $node) {
echo $node->nodeValue;
}
Right now your code is properly fetching the first div that's found, but then you continue treating that div as if it was a DOMNodeList returned from an xpath query, which is incorrect. ->item() returns a DOMNode object, which does NOT have an ->item() method.
