遇到一个平级标签的页面，如下显示：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h2>1. 测试标题一</h2>
<h2 class="lesson-info-h2"><a href="http://www.xxx.xxx.com/1374.html" target="_blank">测试一小标题1</a></h2>

<h2 class="lesson-info-h2"><a href="http://www.xxx.xxx.com/1520.html" target="_blank">测试一小标题3</a></h2>
<h2>2. 测试标题二</h2>
<h2 class="lesson-info-h2"><a href="http://www.xxx.xxx.com/779.html" target="_blank">测试二小标题1</a></h2>
<h2 class="lesson-info-h2"><a href="http://www.xxx.xxx.com/842.html" target="_blank">测试二小标题2</a></h2>

<h2 class="lesson-info-h2"><a href="http://www.xxx.xxx.com/1518.html" target="_blank">测试四小标题2</a></h2>
</body>
</html>我最终要取得的值是
测试标题一
测试一小标题1，小标题1的链接
测试一小标题2，小标题2的链接...
测试标题四
测试四小标题1，小标题1的链接
测试四小标题2，小标题1的链接
我原本使用的是
h2_a = soup.find_all('h2')
for i_a in h2_a:
print i_a这样是可以把需要的h2取到，但想要在继续循环去那些小标题时候，由于得到type(i_a)为<class 'bs4.element.Tag'>
就不知道要怎么取了。
问大神给指点一下。

h2_a = soup.find_all('h2')
for i_a in h2_a:
if i_a.a:
print (i_a.text,'，',i_a.a['href'])
else:
print (i_a.text)python3下的。python2的print不知道怎么写了，不知是否符合你的要求

I can't spell Chinese for the bad OS.
I thinke that we can solve this question using re.
import re
resList = b = re.findall(r'<h2>(.*?)</h2>([\w\W]*?)(?=((<h2>)|(</body>)))',html.replace('\n',''))then: suppose a in resList, a[0] is the parent title, and a[1] is the sub content.
try it.
