真心求教正则表达式
谁帮我把以下代码中，用正则表达式提取以下3个数据呢？
第一：alt="Mexico" 中的 Mexico
第二：7732078 中的 7732078
第三：A 14 中的 A 14

 
 
Mexico 7732078 

 
A 14 
 
 
China 7528398 

 
A 15 
 
 

谢谢了。

PHP code
<?php $str=<<<HTML
<div class="items">  
<a class="imo-block" href="/site/details?imo=7732078">  
<img title="Mexico" src="/images/flags/mx.png" alt="Mexico"> <span class="imo">7732078</span>  
<br>  
<span class="vessel-name">A 14</span>  
</a>  
<a class="imo-block" href="/site/details?imo=7528398">  
<img title="Mexico" src="/images/flags/mx.png" alt="China"> <span class="imo">7528398</span>  
<br>  
<span class="vessel-name">A 15</span>  
</a>

HTML;

preg_match_all('/alt="(.*?)"|class="imo">(.*?)(.*?)',$str,$matchs);
print_r($matchs);
<br><font color="#e78608">------解决方案--------------------</font><br>
$re1 = '/alt="[a-zA-Z]*[^"]/i';<br>$re2 = '/<span class="imo">\d*[^\$re3 = '/<span class="vessel-name">[a-zA-Z0-9 ]*[^\$match ='';<br>preg_match_all($re1, $str, $match);<br>echo '<pre class="brush:php;toolbar:false">';<br>print_r($match);<br>第一个$re1还有点问题，你在想一想吧 <div class="clear">
                 
              
              
        
            </div>
