这里对Python很新。我正在运行selenium web驱动程序,以便从网站查询一些信息(只能从我的组织访问,是的SQL查询会好得多,但这是我目前正在工作的)。我正在使用Selenium的.text
方法从表中检索文本而我print(XXX.text)
,这将返回这样的内容。
XXX.pdf
[Remove]
XXX.pdf
[Remove]
etc...
问题是我想删除,[Remove]
,以便我留下类似的东西:
XXX.pdf
XXX.pdf
甚至更好
XXX.pdf, XXX.pdf
这是我到目前为止所尝试过的,但没有奏效。
dataElement = driver.find_element_by_css_selector('''blah blah blah''')
datasheets = str(dataElement.text)
datasheets.replace('[Remove]','')
print(datasheets)
Python 3.5 Selenium 2
谢谢你的帮助。 :)
In [26]: data = '''\
...: XXX.pdf
...: [Remove]
...: XXX.pdf
...: [Remove]\
...: '''
In [27]: def func(string, rep):
...: return ', '.join([x for x in string.split('\n') if x != rep])
...:
In [28]: func(data, '[Remove]')
Out[28]: 'XXX.pdf, XXX.pdf'
你可以使用类似的东西。
它在结果中打印了什么?也许你忘了什么。
dataElement = driver.find_element_by_css_selector('''blah blah blah''')
datasheets = str(dataElement.text)
datasheets = datasheets.replace('[Remove]','')
print(datasheets)
试试这个:
l = s.split('[Remove]')
s = ', '.join(l)
你需要做这样的事情来解析你的输出。
dataElement = driver.find_element_by_css_selector("blah blah blah")
#I don't know what type is this one, but I asume it's a iterable.
removes = Set(["[remove]","[remove1]", "[remove2]"])
#You can have a set of the strings you want to remove
for data in dataElement:
#for every unit in this iterable variable we'll do the next lines
if str(data) in removes == False:
#if something it is not actually in the set of unwanted stuff.
print(str(data))
#this is your useful output
#whatever you wanna do to the filtered output.
else:
#this is the stuff you don't want to use, the [remove] ones
我希望这会给你一个暗示。问候。
