How can I make sublists from a list based on strings in Python?

I have a list like this:

Python

['<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">']

From this I want to make sublists like:

Python

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

How can I do that?

Thanks.

What I have tried:

Python

<pre><pre lang="Python">myList = []
for l in myList:
    a = l.split()
    print(a)
    idn += a[1]
    language += a[2]
    date += a[3]
    time += a[4]
    timezone += a[5]

Your inputs are actually XML tags without a closing tag. So what you can do, is using xml.etree.ElementTree to parse (your string + </text>) and then use the attributes on the parsed tag:

Python

import xml.etree.ElementTree

inputs = ['<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 = []
# more arrays if you want

for l in inputs:
    element = xml.etree.ElementTree.fromstring(l + "</text>")
    attributes = element.attrib
    ids.append(attributes["id"])
    dates.append(attributes["date"])
    # ... and so on, if you have more arrays

print(ids)
print(dates)

Solution 1

You need to split each line into the tokens separated by spaces. You then need to split each token separated by '='. You then have a keyword and associated value which you can use to make the new lists.
