如何在php中获取Span标签文本？

Question

I am scraping a website in PHP. I have scraped all the required data but I am unable to scrape span tag text.

Expected Output: Apr 20,2017

<span title="" data-toggle="tooltip" data-original-title="Posted On">
                                        <i class="calendar rz-calendar"></i>Apr 20, 2017
                                    </span>
$html = file_get_contents($url);
libxml_use_internal_errors( true);
$doc = new DOMDocument;
$doc->loadHTML($html);
$xpath = new DOMXpath( $doc);

$node = $xpath->query( '//span[@data-original-title="Posted ON"]');

Answer 1

Problem in your code is //span[@data-original-title="Posted ON"] ON is not in capitals it is like this On

Try this code snippet here

<?php
ini_set('display_errors', 1);


$doc = new DOMDocument;
$doc->loadHTML('<span title="" data-toggle="tooltip" data-original-title="Posted On">
                                        <i class="calendar rz-calendar"></i>Apr 20, 2017
                                    </span>');
$xpath = new DOMXpath( $doc);
$nodeList = $xpath->query( '//span[@data-original-title="Posted On"]');
foreach($nodeList as $node)
{
    echo trim($node->textContent);
}
