My code works well, I have no problem extracting what I need. my problem is in some difference coming from using the response of the web service to a different result of doing the same but with the value of the web service saved in a variable. I have this blocker for days, and I hope you please help.
NOTE: the suggested duplicate questions answers don't work for me, this isn't a duplicate question.
I'm consuming a web service. the answer I get is stored in the variable answerService, this is a very long string and after this I extract what is inside the tag span that has this structure:
<span style = "font-weight: bold"> xxx </ span>
"xxx" is what I want to extract
#with that I get the "xxx"
arraySpan = re.findall(r'<span style="font-weight:bold">(.*?)<', answerService)
I get an array of "n" length according to the span existing with this structure.
If I do this directly from the web service it does not work and I only get this answer:
['áGILMENTE']
Now, if I put the response of the web service sameStringOfAnswer in my code, the result is different:
print(arraySpan)
['ADV', 'áGILMENTE']
By logic the answer is the same and never changes, for some strange reason in real time when I get the response from the web service, I only get ['áGILMENTE'] when the answer I expect is ['ADV', 'áGILMENTE']
This is the key piece that shows that 2 span is always coming with the structure I need:

Why are you using regex to parse html?

Mar 27 at 14:52
@TheIncorrigible1 I'm new to python, maybe I'm doing some bad practice, but it's the way I found to extract what I need.

Mar 27 at 14:53
@TheIncorrigible1 I ask you please do not mark my answer as resolved, beyond whether I am doing a bad practice, I have a functional code, and the problem I have could also occur if done differently. please I want you to see my problem, it's kind of weird.

Why are you using regex to parse html?

@TheIncorrigible1 I'm new to python, maybe I'm doing some bad practice, but it's the way I found to extract what I need.

@TheIncorrigible1 I ask you please do not mark my answer as resolved, beyond whether I am doing a bad practice, I have a functional code, and the problem I have could also occur if done differently. please I want you to see my problem, it's kind of weird.

@Ralf is not duplicated, I ask you please do not mark my answer as duplicate. My code works well, I have no problem extracting what I need. my problem is in some difference coming from using the response of the web service to a different result of doing the same but with the value of the web service saved in a variable. I have this blocker for days, and I hope you please help.

The HTML from the webservice contains:
<span style="font-weight:bold"> ADVn </span>
But your minified code contains the tag without the newline n:
<span style="font-weight:bold"> ADV </span>
You can test the difference yourself:
>>> pattern = r'<span style="font-weight:bold">(.*?)<'
>>> re.findall(pattern, '<span style="font-weight:bold">AAAn<')
[]
>>> re.findall(pattern, '<span style="font-weight:bold">AAA<')
['AAA']
That is why the are different. You should have mentioned that you use a minifier, as they alter the HTML and you can not use regex after that and still expect the same output.
This whole problem would have been avoided if you used an XML parser instead of regex, just like the linked question suggests: RegEx match open tags except XHTML self-contained tags

You should really really use a parser. Try BeautifulSoup. Here's some code that does what you want to get you started. gist.github.com/akent/86dd72a085d452e8db5f4d76c3cce2c9
