DOMXpath-获取元素的href属性和文本值 [英] DOMXpath - Get href attribute and text value of an a element

问题描述

所以我有一个像这样的HTML字符串:

So I have a HTML string like this:

<td class="name">
   <a href="/blah/somename23123">Some Name</a>
</td>
<td class="name">
   <a href="/blah/somename28787">Some Name2</a>
</td>

使用XPath，我可以使用以下Xpath查询来获取href属性的值:

Using XPath I'm able to get value of href attribute using this Xpath query:

 $domXpath = new \DOMXPath($this->domPage);
 $hrefs = $domXpath->query("//td[@class='name']/a/@href");
 foreach($hrefs as $href) {...}

这样获得文本值甚至更容易:

And It's even easier to get a text value, like this:

 // Xpath auto. strips any html tags so we are 
 // left with clean text value of a element
 $domXpath = new \DOMXPath($this->domPage);
 $names = $domXpath->query("//td[@class='name']/");
 foreach($names as $name) {...}

现在我很好奇，我如何才能将这两个查询组合在一起而只用一个查询来获得两个值(如果这样甚至可以的话?).

Now I'm curious to know, how can I combine those two queries to get both values with only one query (If it's something like that even posible?).

推荐答案

获取

//td[@class='name']/a

，然后使用nodeValue提取文本，并使用getAttribute('href')提取属性.

and then pluck the text with nodeValue and the attribute with getAttribute('href').

除此之外，您还可以将Xpath查询与联合运算符|结合使用，从而可以使用

Apart from that, you can combine Xpath queries with the Union Operator | so you can use

//td[@class='name']/a/@href|//td[@class='name']

也是.
