Question

Sorry, if I posted a weird question. Now, I am explaining it properly.

I am trying to scrap a data from a web page say for example from: http://www.koolkart.com/nokia-lumia-800-p8251

I am trying to get price of the device listed in the table near “saholic” it is “Rs. 17759/-” and xpath to it is "//*[@id="price-chart"]/tbody/tr[1]/td[3]"

Now, when I execute the xpath in chrome, it gives the price with space

"

                                Rs. 17759/-
                                "

Now, when I execute it in php

<?php
$xpath = '//*[@id="price-chart"]/tbody/tr[1]/td[3]';          
$html = new DOMDocument();
@$html->loadHTMLFile('http://www.koolkart.com/nokia-lumia-800-p8251');
$xml = simplexml_import_dom($html);   
if (!$xml) {
    echo 'Error while parsing the document';
    exit;
}
echo $xml;
$source_image = $xml->xpath($xpath);
print_r($source_image);
?>

it gives error !

So, is there any solution how to remove those trailing spaces or any other way how to get that price?

Answer 1

I will assume you want the price then.

You don’t get the same results in the browser and your script because the tbody tag is added by your browser, but isn’t part of the source.

You can use an expression like this :

'//*[@id="price-chart"]/tr[1]/td[3]'
