我无法获得XPath这些值使用Mozilla Firebug通常我做：有什么建议？

预先感谢您！

<?php 
    ini_set('display_errors', 1); 

    $url = 'http://www.asl1.liguria.it/templateProntoSoccorso.asp'; 

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE); 
    curl_setopt($ch, CURLOPT_HEADER, 0); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); 
    curl_setopt($ch, CURLOPT_PROXY, ''); 
    $data = curl_exec($ch); 
    curl_close($ch); 

    $dom = new DOMDocument(); 
    @$dom->loadHTML($data); 

    $xpath = new DOMXPath($dom); 

    $Number = $xpath->query('/html/body/table/tbody/tr/td[2]/table[2]/tbody/tr/td[3]/table/tbody/tr[2]/td[1]/table/tbody/tr/td/div[1]/div[3]/div[2]'); 

    foreach($Number as $node) 
    { 
     echo "Number: " .$node->nodeValue; 
     echo '<br>'; 
     echo '<br>'; 
    }

我解决下一个值...这里你是正确的代码

<?php 
    ini_set('display_errors', 1); 

    $url = 'http://www.asl1.liguria.it/templateProntoSoccorso.asp'; 

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE); 
    curl_setopt($ch, CURLOPT_HEADER, 0); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); 
    curl_setopt($ch, CURLOPT_PROXY, ''); 
    $data = curl_exec($ch); 
    curl_close($ch); 

    $dom = new DOMDocument(); 
    @$dom->loadHTML($data); 

    $xpath = new DOMXPath($dom); 

    $Number = $xpath->query('(//div[@class="datiOspedaleCodici"]/div[1]/text())[1]'); 

    foreach($Number as $node) 
    { 
     echo "Number: " .$node->nodeValue; 
     echo '<br>'; 
     echo '<br>'; 
    }  
?> 

的打印...

Answer 2

这应该工作：

1. 值从第一个元素：

   substring-after(//div[@class="datiOspedaleCodici"]/div[1]/text(), ":") 
   

2. 从第二：

   substring-after(//div[@class="datiOspedaleCodici"]/div[2]/text(), ":") 
   

   ...等

只是增加/div[x]指数得到
