Xpath php 获取链接 [英] Xpath php fetch links

问题描述

我正在使用此示例从网站获取链接:

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";
}

效果很好；获取所有链接；但我无法获得链接的实际标题"；例如，如果我有:

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>

我也希望能够获取Google"字词.

I want to be able to fetch 'Google' term too.

我对 xpath 有点迷茫，而且很陌生.

I'm little lost and quite new to xpath.

推荐答案

试试这个:

$link_title = $href->nodeValue;
