I have a multiline string variable which includes multiline of system log like below, and I would like to extract the JSON part only
System 123456
Logs start 2021-07-03 12:00:00
<event> {log_in_json}
<event> {log_in_json}
I using find to search over the string variable but this only allow me to get the first occurrence. Anyone could advise?
start = var.find(<event>)
end = var.find("}}")
extracted_line = var[start:end+len("}}")]
json_str = extracted_line.lstrip(<event>)
print(json_str)
Using the optional second argument to the find method, we can set the starting
point for the search. So, second and following times around, we'll start where
we previously found the last match (end), until the method returns -1:
var = '''
System 123456
Logs start 2021-07-03 12:00:00
<event> {log_in_json}
<event> {log_in_json2}
'''
start = var.find('<event>')
while start > 0:
end = var.find("}", start)
extracted_line = var[start:end+len("}")]
json_str = extracted_line.lstrip('<event> ')
print(json_str)
start = var.find('<event>', end)
# {log_in_json}
# {log_in_json2}
