查找两个字符串之间的文本

Question

I've a big text like the following excerpt:

test = '''
Sra. Montero.- ¡No, no! No empecemos.   
Sr. Jefe de Gabinete de Ministros.- Respetuosamente se lo digo...   
Sra. Montero.- El senador Fernández
Sra. Montero.- ¡No, no! No empecemos.   
Sr. Jefe de Gabinete de Ministros.- Respetuosamente se lo digo...   
Sra. Montero.- El senador Fernández
Sra. Montero.- ¡No, no! No empecemos.   
Sr. Jefe de Gabinete de Ministros.- Respetuosamente se lo digo...   
Sra. Montero.- El senador Fernández
Sra. Montero.- ¡No, no! No empecemos.   
Sr. Jefe de Gabinete de Ministros.- Respetuosamente se lo digo...   
Sra. Montero.- El senador Fernández
'''

I'd like to get all the text between the string "Sr. Jefe de Gabinete de Ministros.-" and the string "Sr{{ random_text_here }}.-". So in this example what I'd like to get would be the following:

data = ['Respetuosamente se lo digo...', 'Respetuosamente se lo digo...', 'Respetuosamente se lo digo...']

I know the regex clause has to be non-greedy and I already tested something like this:

bw_sr = re.compile('\.\-(.+?)Sr[.+]\.\-') #non greedy regexx              
data = bw_sr.findall(test)

But I end up getting an empty list. I tried several clauses but I can't seem to get to a solution.

Answer 1

your regex was wrong (this one [.+] was between brackets which defined a character range, so it wasn't working, among other issues, like no way to distinguish between "Sr." and "Sra" (seems what you wanted to do seeing the output), which I fixed by doing Sr\\. ).

I came up with that one which matches the formulas and also "El senador Fernández", etc... there's no criterion to filter those. I also added \\s* before the capturing group to "strip" blanks:

bw_sr = re.compile('\.\-\s*(.+?)\nSr\..+?\.\-')
data = bw_sr.findall(test)

print(data)

result:

['¡No, no! No empecemos.', '¡No, no! No empecemos.', '¡No, no! No empecemos.', '¡No, no! No empecemos.']

Answer 2

It's work:

bw_sr = re.compile('\.\- (.*)')
data = bw_sr.findall(test)
