Question

嗨，我真的需要一些帮助。我对Xpath这个概念很陌生，但是我正在考虑它。

但是我遇到了以下代码，我试图获得文章的正文，所以在第一个例子中这将是

“法院关闭了180万英镑碳信用额投资公司。 ...... 破产服务人员强迫他们进行清算过度销售碳信用额销售额。 ... “

以及第一个例子中的日期也是

“作者Michelle Abrego | 2014年7月14日”

我可以使用：
来获得标题
  $website_row = $website_xpath->query('//div[@id="ctl00_ctl00_mainContentPlaceHolder_mtrResults"]//h3[@class="headline"]/a[@id]');

if($website_row->length > 0){

  foreach($website_row as $row){

      echo $row->nodeValue . "<br/><br/>";
      $newTitle = $row->nodeValue;
      $dataStoreForTable['title'][]=$newTitle;

  }

}

但我似乎无法到达身体或日期。

    <div class="columnOne">

  <div id="ctl00_ctl00_mainContentPlaceHolder_mtrResults">

      <span id="ctl00_ctl00_mainContentPlaceHolder_mlblResultCount">Results 1 - 10 of about 57 for 'Carbon Credit Fraud' sorted by date - </span>
