Question

我试图从xml输出中提取关键字，如下所示：

http://clients1.google.com/complete/search?hl=en&output=toolbar&q=test+a

我试过把下面的内容放在一起，但我似乎没有得到任何错误或任何输出。有什么想法吗？

import urllib2 as ur
import re

f = ur.urlopen(u'http://clients1.google.com/complete/search?hl=en&output=toolbar&q=test+a')
res = f.readlines()
for d in res:
  data = re.findall('<CompleteSuggestion><\/CompleteSuggestion>',d)
  for i in data:
    print i
    file = open("keywords.txt", "a")
    file.write(i + '\n')
    file.close()

我想，

存储XML文件中的关键字列表，使用正则表达式进行解析

谢谢，

from urllib2 import urlopen 
import re

xml_url = u'http://clients1.google.com/complete/search?hl=en&output=toolbar&q=test+a'
xml_file_contents = urlopen(xml_url).readlines()

keywords_file = open("keywords.txt", "a")

for entry in xml_file_contents:
    output = "\n".join(re.findall('data=\"([^\"]*)',entry))
    print output
    keywords_file.write(output + '\n')

keywords_file.close()

输出：

test anxiety
test america
test adobe flash
test automation
test act
test alternator
test and set
test adblock
test adobe shockwave
test automation tools
