I want to automatically change links like this:

<a href="https://www.burning-glass.com/wp-content/uploads/rebooting_jobs_2017.pdf">Rebooting Jobs: How computer science skills spread in the job market</a>

To this:

<pre><a href="https://www.burning-glass.com/wp-content/uploads/rebooting_jobs_2017.pdf" title="Rebooting Jobs: How computer science skills spread in the job market ">Rebooting Jobs: How computer science skills spread in the job market</a>

It's to make links across my site more acessiblefor the blind.

A friend who knows regex suggested I use

Quote:

<(a href=[^>]*)>([^<]*)<\/a>>

to make the two groups and

Quote:

<$1 title="$2">$2

To do the replacement. I used Regex101 and it seemed to work fine at first, but for no reason I can find it sometimes now refuses to match any terms! Can anyone suggest a rephrase of the first search string to make it work as needed?

What I have tried:
