I have this string
<h2 id="1">1. Item 1</h2>
<h2 id="1.2">1.2. Item 1.2</h2>
<h2 id="2">2. Item 2</h2>
I need to match headers which have int numbers 1. and 2. in the text. Not 1.2.
I do it like this
<h2.*?>(.*?)[0-9]\.\s+(.*?)</h2>
It matches all headers. Where am I wrong?
Remove (.*?)
and then add a +
after [0-9]
because (.*?)
exists before [0-9]
will match any character zero or more times, which in-turn matches 1.
<h2.*?>[0-9]+\.\s+(.*?)</h2>
您可以使用正则表达式:
<h[1-6][^>]*>\d{1}\.(?!\d{1}\.)([^<]*)<\/h[1-6]>
