matching string using regular expression - regex

Question

text = "hellovision hey creator yoyo b creator great publisher"
I want to extract creator's name and publisher's name from text.
The result will be,
creator = hellovision hey, yoyo
publisher = great
How can I get text using regular expression?
Do I need to use span()..?
This is my code.
def preprocess2(text):
text_list = test.split(' ')
lyricist = []
composer = []
music_arranger = []
temp = []
lyricist.clear()
composer.clear()
music_arranger.clear()
for i in range(0, len(text_list)):
if text_list[i] == 'creator':
print(len(text_list))
for a in range(0, i-1):
temp.append(text_list[a])
lyricist.append(''.join(temp))
temp.clear()
for b in range(0, i+1):
print(b)
text_list.pop(b)
print(len(text_list))
break
elif text_list[i] == 'pulisher':
for a in range(0, i-1):
temp.append(text_list[a])
composer.append(''.join(temp))
temp.clear()
for b in range(0, i+1):
text_list.pop(b)
break
i = i +1
return text_list

If you split your array using regex with a capture group, the value that you split on will also be passed into the output array.
You can then loop through looking for 'creator' or 'publisher' and in each case, pass the previous entry into the proper collection.
const text = "hellovision hey creator yoyo b creator great publisher"
const splitArr = text.split(/(creator|publisher)/)
const creators = [], publishers = []
let i = -1, len = splitArr.length
while(++i < len){
if(splitArr[i] == "creator") creators.push(splitArr[i-1].trim())
else if(splitArr[i] == "publisher") publishers.push(splitArr[i-1].trim())
}
console.log("creators: ", creators)
console.log("publishers: ", publishers)
