Question

我希望我能问这个问题,我就在四舍五入周围搜寻,找到了简单的问题,但没有为我找到解决办法。

I have HTML like this: <h1>Beatles: A Hard Days Night</h1> now I would like a regex to match everything AFTER the colon. So A Hard Days Night in this case.

这是我尝试的:

$pattern = "/<h1>:(.*)</h1>/";

但是,这只是空洞的。

Answer 1

The following regex should amount that:

<h1>[^:]+:s+([^<]+)

权力壳牌测试:

PS>  <h1>Beatles: A Hard Days Night</h1>  -match  <h1>[^:]+:s+([^<]+) ; $Matches
True

Name                           Value
----                           -----
1                              A Hard Days Night
0                              <h1>Beatles: A Hard Days Night

没有什么解释:

<h1>    # match literal <h1>
[^:]+   # match everything *before* the colon (which in this case
        # shouldn t include a colon itself; if it does, then use .*)
:       # Literal colon
s+     # Arbitrary amount of whitespace
([^<]+) # Put everything up to the next < into a capturing group.
