Question

I need help with regex in python.

I’ve got a large html file[around 400 lines] with the following pattern

text here(div,span,img tags)

<!-- 3GP||Link|| --> 

text here(div,span,img tags)

So, now i am searching for a regex expression which can extract me this-:

Link

The given pattern is unique in the html file.

Answer 1

>>> d = """
... Some text here(div,span,img tags)
...
... <!-- 3GP||**Some link**|| -->
...
... Some text here(div,span,img tags)
... """
>>> import re
>>> re.findall(r'\<!-- 3GP\|\|([^|]+)\|\| --\>',d)
['**Some link**']

• r'' is a raw literal, it stops interpretation of standard string escapes
• \<!-- 3GP\|\| is a regexp escaped match for <!-- 3GP||
• ([^|]+) will match everything upto a | and groups it for convenience
• \|\| --\> is a regexp escaped match for || -->
• re.findall returns all non-overlapping matches of re pattern within a string, if there’s a group expression in the re pattern, it returns that.
