Question

我的HTML代码如下所示：

 <br><a href="/drink12xy569.html">Alien Suicide</a>
 <br><a href="/drink792.html">All Jacked Up</a>
 <br><a href="/drink3805.html">All Night Hunter</a>
 <br><a href="/drink796.html">Alley Shooter</a>
 <br><a href="/drink10013.html">Alligator Sperm</a>
 <br><a href="/drink804.html">Almond Delight</a>
 <br><a href="/drink11135.html">Almond Gravy</a>
 <br><a href="/drink7519.html">Almond Joy #2</a>
 <br><a href="/drinks1r2563.html">Almond Kiss</a>
 <br><a href="/drink12xy578.html">Amaretto Pie</a>
 <br><a href="/drink11144.html">Amaretto Sourball</a>
 <br><a href="/drinkp15q144.html">Ambuco Cinnamon Shooter</a>
 <br><a href="/drink835.html">Amenie Mama</a>
 <br><a href="/drink7521.html">American Death</a>

我需要帮助才能在<br>之间提取标题然后将其打印出来。然后我需要帮助将这些信息以及我已经提取的其他信息写入我可以使用gui界面搜索的文本文档。我有单独的代码，最后可以将它们放在一起，我只需要概念帮助。

我美丽的汤爬行看起来像这样：

import urllib2
from bs4 import BeautifulSoup
url=[]
for i in range(28):
    url="http://www.drinksmixer.com/cat/3/"
    page = urllib2.urlopen("http://www.drinksmixer.com/cat/3/")
    soup = BeautifulSoup(page.read())
    links=soup.find_all('a')

for link in links:
    if "drink" in link ['href']:
        print link['href']
        print "****\n\n"
        url="http://drinksmixer.com"+link['href']
        page1=urllib2.urlopen(url)
        soup1=BeautifulSoup(page1.read())
        divs=soup1.find('div', {"class":"ingredients"})
        print divs.text.encode("utf-8")

我的gui界面如下所示：

import Tkinter
from Tkinter import *

def show_entry_fields():
   print("Shot Name: %s" % (e1.get()))

master = Tk()
Label(master, text="Shot Name").grid(row=0)

e1 = Entry(master)

e1.grid(row=0, column=1)

Button(master, text='Search', command=show_entry_fields).grid(row=3, column=1, sticky=W, pady=4)

mainloop( )

我只是需要帮助在我提取的信息中实施搜索。

设计用户界面并不容易。你的代码几乎没问题。我把它分成了函数，并添加了你要求的基本搜索。

import urllib2
from bs4 import BeautifulSoup
import Tkinter
from Tkinter import *

e1 = None
links = []

def get_drinks():
    global links
    for i in range(28):
        url="http://www.drinksmixer.com/cat/3/" + i
        page = urllib2.urlopen(url)
        soup = BeautifulSoup(page.read())
        links.append(soup.find_all('a'))

def get_recipe(drink_name):
    print drink_name
    for link in links:
        if "drink" in link ['href'] and drink_name in link.contents:
            #print link['href']
            print "****\n\n"
            url="http://drinksmixer.com"+link['href']
            page1=urllib2.urlopen(url)
            soup1=BeautifulSoup(page1.read())
            divs=soup1.find('div', {"class":"ingredients"})
            recipe = divs.text.encode("utf-8")
            return recipe

def show_entry_fields():
    drink_name = e1.get()
    print("Shot Name: %s" % drink_name)
    recipe = get_recipe(drink_name)
    print recipe # or better yet, popup
    # tkMessageBox.showinfo(drink_name, recipe)

def main():
    global e1
    master = Tk()
    Label(master, text="Shot Name").grid(row=0)
    e1 = Entry(master)
    e1.grid(row=0, column=1)
    Button(master, text='Search', command=show_entry_fields).grid(row=3, column=1, sticky=W, pady=4)
    mainloop()

if __name__ == "__main__":
    get_drinks()
    main()

美丽的汤从中爬行并从中提取文字
