DomCrawler复合div嵌套

Question

我在使用dom爬虫获取数据时遇到了困难。我想取名为“Avocado”和“GB1.50”，我想我可以这样做

 $message = $crawler->filterXPath('h3')->text(); 



  <div class="product"> 
  <div class="productInner"> 
  <div class="productInfoWrapper"> 
  <div class="productInfo"> 
  <h3> 
  <a href="http://website.com" > 
  Avocado  
  <img src="pic.jpg" alt="" /> 
  </a> 
  </h3> 
  </div> 
  </div> 
 <div class="pricingAndTrolleyOptions"> 
 <div class="pricing"> 
<p class="pricePerUnit"> 
 £1.50<abbr title="per">/</abbr><abbr title="unit"><span                 class="pricePerUnitUnit">unit</span></abbr> 
   </p> 
 <p class="pricePerMeasure">£1.50<abbr 
title="per">/</abbr><abbr 
title="each"><span class="pricePerMeasureMeasure">ea</span></abbr> 
 </p> 
</div> 
</div>
</div>

Answer 1

要获取h3文本：

$message = $crawler->filterXPath('//div[@class="productInfo"]/h3')->text();

要获得价格(即pricePerMeasure类)：

$price= $crawler->filterXPath('//p[@class="pricePerMeasure"]')->text();
