PHP regular expression subpattern behaviour
- by codecowboy
I want to match both the src and title attributes of an image tag:
pattern:
<img [^>]*src=["|\']([^"|\']+["|\'])|title=["|\']([^"|\']+)
target:
<img src="http://someurl.jpg" class="quiz_caption" title="Caption goes here!">
This pattern gives me one unwanted match, title="content", and the match I actually want which is the value between the quotes after the word 'title', i.e 'content'.
So, my matches are:
<img src="http://someurl.jpg
http://someurl.jpg
title="Caption goes here!"
Caption goes here!
Is there a way to avoid the third of these matches? I'm using PCRE in PHP 5.2.x
