如何基于python中的字符串从列表中创建子列表? [英] How can I make sublists from a list based on strings in python?

问题描述

我有一个这样的列表:

['<text id="32a45" language="ENG" date="2017-01-01" time="11:00" timezone="Eastern">',
'<text id="32a47" language="ENG" date="2017-01-05" time="1:00" timezone="Central">',
'<text id="32a48" language="ENG" date="2017-01-07" time="3:00" timezone="Pacific">']

由此，我想创建如下子列表:

From this I want to make sublists like:

id = ["32a45", "32a47", "32a48"]
date=["2017-01-01", "2017-01-05", "2017-01-07"]

我该怎么做?

谢谢.

这是

This was the original question It is a broken xml file and tags are messed up, hence I cannot use xmltree. So I am trying something else.

推荐答案

使用re.search()函数的简单解决方案:

Simple solution using re.search() function:

import re

l = ['<text id="32a45" language="ENG" date="2017-01-01" time="11:00" timezone="Eastern">',
'<text id="32a47" language="ENG" date="2017-01-05" time="1:00" timezone="Central">',
'<text id="32a48" language="ENG" date="2017-01-07" time="3:00" timezone="Pacific">']

ids, dates = [], []
for i in l:
    ids.append(re.search(r'id="([^"]+)"', i).group(1))
    dates.append(re.search(r'date="([^"]+)"', i).group(1))

print(ids)    # ['32a45', '32a47', '32a48']
print(dates)  # ['2017-01-01', '2017-01-05', '2017-01-07']
