I'm using this example to fetch links from a website :
http://www.merchantos.com/makebeta/php/scraping-links-with-php/
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//a");
for ($i = 0; $i < $hrefs->length; $i++) {
$href = $hrefs->item($i);
var_dump($href);
$url = $href->getAttribute('href');
echo "<br />Link stored: $url";
}
It works well; getting all the links; but I cannot get the actual 'title' of the link; for example if i have :
<a href="www.google.com">Google</a>
I want to be able to fetch 'Google' term too.
I'm little lost and quite new to xpath.
Try this:
$link_title = $href->nodeValue;
You are looking for the "nodeValue" of the Textnode inside the "a" node. You can get that value with
$title = $href->firstChild->nodeValue;
Full working example:
<?php
$dom = DomDocument::loadHTML("<html><body><a href='www.test.de'>DONE</a></body></html>");
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//a");
for ($i = 0; $i < $hrefs->length; $i++) {
$href = $hrefs->item($i);
$url = $href->getAttribute('href');
$title = $href->firstChild->nodeValue;
echo "<br />Link stored: $url $title";
}
Prints:
Link stored: www.test.de DONE
