我有字符串 :
Lorem ipsum dolor [mytag]something[/mytag]sit amet, ipsum [mytag]something else[/mytag]a laoreet ultricies
我想得到价值 "某事"和"别的东西" 并替换它。
怎么办?
正则表达式是前进的道路 。
import re
s = Lorem ipsum dolor [mytag]something[/mytag]sit amet, ipsum [mytag]something else[/mytag]a laoreet ultricies
print re.sub(r [mytag](.+?)[/mytag] , r <img src="1"> , s)
您可以使用 "http://pypi.python.org/pypi/bbcode" rel=“nofollow”>bbcode 模块 :
# Using the default parser.
import bbcode
html = bbcode.render_html(text)
因为我认为已经存在[img]:
# Installing simple formatters.
parser = bbcode.Parser()
parser.add_simple_formatter( img , <img src="%(value)" /> )
