XPath does not return all content

[dumb2champ]

Please help regarding scraping website using Xpath...

I want to scrap the main content of a website..but theres a problem...the scripts does not return all content but only the first line of content at main body of website...

Scripts like below....

<?php

//sentimen order
if (PHP_SAPI != 'cli') {
	echo "<pre>";
}

require_once __DIR__ . '/../autoload.php';
$sentiment = new \PHPInsight\Sentiment();

require_once 'Xpath.php';

//my target website
$startUrl = "http://news.sky.com/story/1445575/suspect-held-over-shooting-of-ferguson-police/";

$xpath = new XPATH($startUrl);

// my specific filter
$query = '/html/body/div[2]/div[3]/article/div/div[2]/div[2]';

//start xpath
$strQuery = $xpath->query($query);
$strNode = $strQuery->item(0)->nodeValue;

//THE PROBLEM START HERE..ARRAY SCRIPTS SEEMS WRONG....
$result = array($strNode);

//HERE ALSO
foreach ($result as $string) {

	// calculations:
	$scores = $sentiment->score($string);
	$class = $sentiment->categorise($string);
	
	// output:
	echo "Strings $string \n";
	echo "Dominant: $class, scores: ";
	print_r($scores);
	echo "\n";
}

The scripts output only single line of sentiment but not all the required content...

 

The problem come from array and foreach...

Please help to repair these scripts...Thanks

Look at the previous line.

$strNode = $strQuery->item(0)->nodeValue;

You are only grabbing the first element's node value, and then you force that to be an array. So it's an array with one value.
