[SOLVED] How can I fix this regex in order to get html tag only from a particular url?

Issue

Hello I have a html file with several img tags:

<img src="https://www.pokeyplay.com/imagenes/backend/publicidad.gif" alt="Publicidad" align="left" />
<img src="https://www.pokeyplay.com/imagenes/backend/spacer.gif" alt="sp" />
<img src="imagenes/backend/etiqueta-pyp-pokedex.gif" alt="P&amp;P Pok&eacute;Dex" width="184" height="100" />
<img src="imagenes/backend/spacer.gif" alt="sp" />
<img src="http://urpgstatic.com/img_library/pokemon_sprites/187.png" style="vertical-align:middle" />

In order to stract all img tags I am using the following regexp:

'<img[^>]* src=\"([^\"]*)\"[^>]*>'

But I want to extract only all IMG tags from urpgstatic.com

How can do this?

I did several tries like this:

<img.*?src="(http[s]?:\/\/)urpgstatic.com?([^\/\s]+\/)(.*)[png]$"[^\>]+>

Thanks

Solution

Try this

<img[^>]*(?=\"https?:\/\/(www\.)?urpgstatic\.com)\"([^\"]*)\"[^>]*>

Demo

Also, this will work with grep

grep -iP '<img[^>]*(?=\"https?:\/\/(www\.)?urpgstatic\.com)\"([^\"]*)\"[^>]*>' index.html
