BeautifulSoup：从锚标记中提取文本

Question

我要提取：

• 来自image标签的src的文本和
• div类数据内的定位标记的文本

我成功地提取了img src，但是从锚标记中提取文本时遇到了麻烦。

<a class="title" href="http://www.amazon.com/Nikon-COOLPIX-Digital-Camera-NIKKOR/dp/B0073HSK0K/ref=sr_1_1?s=electronics&amp;ie=UTF8&amp;qid=1343628292&amp;sr=1-1&amp;keywords=digital+camera">Nikon COOLPIX L26 16.1 MP Digital Camera with 5x Zoom NIKKOR Glass Lens and 3-inch LCD (Red)</a>

这是整个HTML页面的链接。

这是我的代码：

for div in soup.findAll('div', attrs={'class':'image'}):
    print "\n"
    for data in div.findNextSibling('div', attrs={'class':'data'}):
        for a in data.findAll('a', attrs={'class':'title'}):
            print a.text
    for img in div.findAll('img'):
        print img['src']

我想做的是 提取图像src（链接）和中的标题div class=data，因此例如：

 <a class="title" href="http://www.amazon.com/Nikon-COOLPIX-Digital-Camera-NIKKOR/dp/B0073HSK0K/ref=sr_1_1?s=electronics&amp;ie=UTF8&amp;qid=1343628292&amp;sr=1-1&amp;keywords=digital+camera">Nikon COOLPIX L26 16.1 MP Digital Camera with 5x Zoom NIKKOR Glass Lens and 3-inch LCD (Red)</a>

应该提取：

Nikon COOLPIX L26 16.1 MP Digital Camera with 5x Zoom NIKKOR Glass Lens and 3-inch LCD (Red)

以上所有答案确实可以帮助我构建答案，因此，我对其他用户提出的所有答案投了赞成票：但是我最终对自己正在处理的确切问题汇总了自己的答案：

正如明确定义的问题一样，我必须以dom结构访问某些兄弟姐妹及其子代：此解决方案将迭代dom结构中的图像，并使用产品标题构造图像名称，并将图像保存到本地目录。
