I'm trying to come up with a regex to be able to parse the following type of strings into groups.
<link rel="alternate" type="application/rss+xml" title="[!PageTitle!]" href="[!SiteRoot!]/feed.xml" />
My regular expression is:
\[\!(.+)\!\]
The problem with this expression is that it seems to pull it all into 1 group:
Found 1 match:
"[!PageTitle!]" href="[!SiteRoot!]" has 1 group:
1. "PageTitle!]" href="[!SiteRoot"
I want dont want the regex to continue...am I missing a boundary? Ideally I want it to find 2 groups ,
[!PageTitle!]
and
[!SiteRoot!]
try:
\[\!(.+?)\!\]
the +
quantifier is greedy, so will match as far as possible in the line, capturing the first [ followed by the last ] in the line. +?
is the non-greedy equivalent.
As an aside, I'm using Rad Software Regular Expression Designer . I like it.
似乎这样可以正常工作:)
\[!(\w+)!\]
