Try this:

<pre><code>\?(.*)
</code></pre>

The parentheses are a capturing group that you can use to extract the part of the string you are interested in.

If the string can contain new lines you may have to use the "dot all" modifier to allow the dot to match the new line character. Whether or not you have to do this, and how to do this, depends on the language you are using. It appears that you forgot to mention the programming language you are using in your question.

Another alternative that you can use if your language supports fixed width lookbehind assertions is:

<pre><code>(?&lt;=\?).*
</code></pre>

If you want to match all chars after "?" you can use a group to match any char, and you'd better use the "$" sign to indicate the end of line.

<code>str.replace(/^.+?\"|^.|\".+/, '');</code>

This is sometimes bad to use when you wanna select what else to remove between "" and you cannot use it more than twice in one string. All it does is select whatever is not in between "" and replace it with nothing.

Even for me it is a bit confusing, but ill try to explain it. <code>^.+?</code> (not anything OPTIONAL) till first <code>"</code> then <code>|</code> Or/stop (still researching what it really means) till/at <code>^.</code> has selected nothing until before the 2nd <code>"</code> using (<code>|</code> stop/at). And select all that comes after with .+.

With this you can get everything Even a new line

I have a feed in Yahoo Pipes and want to match everything after a question mark.

So far I've figured out how to match the question mark using..

<pre><code>\?
</code></pre>

Now just to match everything that is after/follows the question mark.

Regex match everything after question mark?

我有一个在雅虎管道馈送，并希望匹配问号后的一切。到目前为止，我已经知道如何使用..匹配问号。\?现在，为了匹配问号后面/后面的所有内容。
