extract text every line and check in regular expression












-2














Hi I have the following 2 documents amongst many in the form of a list.



Document 1:



 contact
TomGonsalves
985664774
6560,m.d avenue.

harrydsouza
7676764
543,gt,road.


Document 2 in the same python list:



  contact
richard peterson
4563565
87,td street,Ny.


Here both the above text documents(1 and 2) are part of the same. In the text, I need to extract the 1st line after contact,i.e the name. However in Document-1 there are 2 names which I need to extract and just the names.



I need to write a regular expression to fetch the needful and the output should look like



     Names from Document 1 =[tomgonsalves,harrydsouza]
names from document-2=[richard peterson]


Can someone please help me with the reGex script in python 3 for this.There are many docs in the same list which may have different number of names in its contact. I just need to extract the names alone(be it 1 or multiple)

    Honestly, I might prefer just iterating the file line by line and implementing some simple parsing logic.

You can try something like this:



Read the txt file line-by-line. For each line check if it has only alphabets with isalpha() function of string.



In [309]: with open('ff.txt') as f: ## ff.txt is the file you shared
...: for i in f:
...: i = re.sub('n','',i)
...: if i.isalpha():
...: if not i == 'contact':
...: print(i)

You can do this for each file you have.

Although this should be preferred to be attacked by simple text parsing but just in case you want a regex solution, you may use this regex,



(?:^s*[a-zA-Z]+s*|(ns*){2})([w ]+)


Here is a demo



Let me know if this works for you, else please provide more sample input so I can further refine my regex to match your precise input.
