Rancher :
I want use apache RE to parse the string like

and get
XXX : YYY aaa : bbb as the result (XXX YYYY can be any character even japanese or chinese)

I write the regular expression like (<span>([^:]* : [^:]*)</span> *
it only give me the aaa : bbb, it confuse me a lot, how to implement this in right way?

Hard to tell what the Regex is -- since you forgot to turn off the smilies. But from what I can read, it looks like you are using a qualifier at the end.

Anyway... When a subgroup matches multiple times, in a single match, due to a qualifier, then only the last match is retained. If you want all matches of a particular subgroup, I suggest you remove the qualifier, and iterate through multiple times with the find() method.

[EDIT: Sorry, just realized you are not using the built-in Regex engine. Hopefully, Apache has an equivalent that allows the iteration.]

Please turn off the smilies -- it is a checkbox at the very bottom of the post page.

It would depend on how strict you want the search. For example, if you want exactly one ":". And it must be between "<span>" and "</span>, then you could do this...



If you also want to prevent the "<" and ">", while at the same time, prevent matching the case where the ":" is missing, then you could do this...
