here's one way to do it:
import re, cgi
def fixurl(text):
def fixup(m):
link, text = m.groups()
text = text.strip() or link
return "<a href='%s'>%s</a>" % (cgi.escape(link), cgi.escape(text))
return re.sub(r"\[url=([^]]+)\]([^[]*)\[/url\]", fixup, text)
usage:
>>> fixurl("[url=http://www.whatever.org][/url]";)
"<a href='http://www.whatever.org'>http://www.whatever.org</a>"
>>> fixurl("[url=http://www.whatever.org]My link[/url]")
"<a href='http://www.whatever.org'>My link</a>"
</F>
