如果网页包含多个页面，如何提取URL链接？

Question

我正在尝试从Blogspot中提取所选部分的URL链接。

不幸的是，当我运行我的代码时，它只会提取第一页的URL而忽略其他页面。

例如，http://ellywonderland.blogspot.com/

中有9个网址链接和2个网页

但是这些代码只能在第一页中提取7个网址链接，而忽略下一页中的其他网址链接。

代码：

import urllib2 # Please look into the requests library
from bs4 import BeautifulSoup

# Renaming your variables
links_file = open("link.txt")
# No need to split them yourself, theres a method for that
links = link_file.readlines() 


for url in links:
    htmltext = urllib2.urlopen(url).read()
    soup = BeautifulSoup(htmltext)

    # describe your actions with variable names
    relative_tags_to_desired_links = soup.find_all("h3", "post-title entry-title", "name")

    for tag in relative_tags_to_desired_links:
        desired_element = tag.next_element.next_element
        print desired_element.get("href")

'link.txt'包含网址列表（例如）：

http://ellywonderland.blogspot.com/

输出：

 http://ellywonderland.blogspot.com/2011/03/my-vintage-pre-wedding.html

那么，你能帮助我如何阅读Blogspot中的所有页面吗？

谢谢。
