Preg match with only opening match

I have a file that consists of:

<ol type=“1”>

<ol type=“2”>

<ol type=“3”>
… etc

How can use preg_match_all to grab the contents of each (…)? I don’t have a consistent end match pattern to use (and no it’s not the closing <ol>!!)

Is the end of the “…” the starting point for the next <ol>?

OMG having a dumb moment. I just need to explode off the <ol
