Question

... 
<div class="termContainer"> 
<h4>SUMMER 2013</h4> 
<ul> 
<li> 
<a href="url" title="A"> 
<span>A</span> 
</a></li> 
<li><a href="url" title="B"> 
<span>B</span> 
</a></li> 
<li><a href="url" title="C"> 
<span>C</span> 
</a></li> 
</ul> 
</div>

<div class="termContainer"> 
<h4>SPRING 2013</h4> 
...other links 
</div> 
... 

我写一个Perl脚本来获得链接的标题里面

<div class="termContainer"> 

在HTML代码中。我的预期结果是A，B，C。

我真的不知道如何处理它。任何建议？

非常感谢。

use HTML::TreeBuilder::XPath; 

my $html = <<EOFHTML; 
... 
<div class="termContainer"> 
<h4>SUMMER 2013</h4> 
<ul> 
<li> 
<a href="url" title="A"> 
<span>A</span> 
</a></li> 
<li><a href="url" title="B"> 
<span>B</span> 
</a></li> 
<li><a href="url" title="C"> 
<span>C</span> 
</a></li> 
</ul> 
</div> 
... 
<div class="termContainer"> 
<h4>SPRING 2013</h4> 
...other links 
</div> 
... 
EOFHTML 

my $tree = HTML::TreeBuilder::XPath->new_from_content($html); 

foreach my $title ($tree->findvalues('//div[@class="termContainer"]//a/@title')) { 
    print $title, "\n"; 
}
