Python split() without removing the delimiter
PythonSplitDelimiterPython Problem Overview
This code almost does what I need it to..
for line in all_lines:
s = line.split('>')
Except it removes all the '>' delimiters.
So,
<html><head>
Turns into
['<html','<head']
Is there a way to use the split() method but keep the delimiter, instead of removing it?
With these results..
['<html>','<head>']
Python Solutions
Solution 1 - Python
d = ">"
for line in all_lines:
s = [e+d for e in line.split(d) if e]
Solution 2 - Python
If you are parsing HTML with splits, you are most likely doing it wrong, except if you are writing a one-shot script aimed at a fixed and secure content file. If it is supposed to work on any HTML input, how will you handle something like <a title='growth > 8%' href='#something'>?
Anyway, the following works for me:
>>> import re
>>> re.split('(<[^>]*>)', '<body><table><tr><td>')[1::2]
['<body>', '<table>', '<tr>', '<td>']
Solution 3 - Python
How about this:
import re
s = '<html><head>'
re.findall('[^>]+>', s)
Solution 4 - Python
Just split it, then for each element in the array/list (apart from the last one) add a trailing ">" to it.
