[类别]：开放问题：
在我不想要的每个标题中...我想编写一个正则表达式来删除这个...
我们可以做的任何事情来删除开头的所有字母[第一个：应该这样做。

预先感谢您，我也会尝试自己找到解决方案。
I am trying to parse the yahoo answers feed - http://answers.yahoo.com/rss/allq
The issue is that the titles have
[ Category ] : Open Question :
in every title that I do not want... I want to write a regexp to remove this...
anything that we can make to remove all the letters in the starting [ and the first : should do it.
there is a space after the : also, we need to remove that too.
Thanks for this in advance, I will also try to find a solution myself.

您是否考虑过使用 Yahoo 的 YQL 服务来解析此提要（或其他网页）？
他们已经提供了示例查询供您在 Yahoo 获取答案数据：
answers.getbycategory:
http://developer.yahoo.com/yql/console/#h= select%20*%20from%20answers.getbycategory%20where%20category_id%3D2115500137%20and%20type%3D%22resolved%22
answers.getbyuser:
http://developer.yahoo.com/yql/console/#h=选择%20*%20from%20answers.getbyuser%20where%20user_id%3D%22YbaMGtHFaa%22
answers.getquestion:
http://developer.yahoo.com/yql/console/#h=选择%20*%20from%20answers.getquestion%20where%20question_id%3D%2220090526102023AAkRbch%22
answers.search:
http://developer.yahoo.com/yql/console/#h=选择%20*%20from%20answers.search%20where%20query%3D%22cars%22%20and%20category_id%3D2115500137%20and%20type%3D%22resolved%22
（仅供参考，以防您我不知道这个方便的服务，而不是使用正则表达式进行屏幕抓取。）
Have you considered using Yahoo's YQL service to parse this feed (or other web pages)?
They already have sample queries for you to get at Yahoo Answers data:
answers.getbycategory:
http://developer.yahoo.com/yql/console/#h=select%20*%20from%20answers.getbycategory%20where%20category_id%3D2115500137%20and%20type%3D%22resolved%22
answers.getbyuser:
http://developer.yahoo.com/yql/console/#h=select%20*%20from%20answers.getbyuser%20where%20user_id%3D%22YbaMGtHFaa%22
answers.getquestion:
http://developer.yahoo.com/yql/console/#h=select%20*%20from%20answers.getquestion%20where%20question_id%3D%2220090526102023AAkRbch%22

(Just an FYI in case you weren't aware of this convenient service. I use it instead of screen scraping with RegEx's.)
以下正则表达式应该完成这项工作：
c# 中的使用示例：
它的作用是以
[括号开头，并采用任何字符，直到匹配:并采用以下空格。希望这有帮助，
汤姆.
感谢@ cmptrgeekken 指出了非贪婪的事情！
the following regex should do the job:
Usage sample in c#:
What it does is start with an
[bracket and take any characters until it matches a:and take the follwing space.Hope this helps,
Tom.
Thanks @ cmptrgeekken for pointing the non greedy thing out!
