I want to delete the custom HTML that is in all posts. It is impossible for me to edit one post at a time because there have been many posts that I have published.

I want to delete it using Regex via Search Regex plugin.

I am confused about the part that I want to delete. I want to delete everything from the <!-- wp:html --> tag to <!-- /wp:html -->. How to do it?

  • Since you're using a specific plugin, please refer to their documentation and support channels. It may vary depending on the plugin itself. If you're open to custom-code solutions you may still get answers here, or might also want to try asking on StackOverflow since that would be more of a MySQL question than a WP-specific one. – WebElaine Jun 12 '20 at 15:50
  • This can be rephrased simpler as how do I remove all the custom HTML blocks in my posts automattically? Note that by choosing Regex to do this you make this problem 50x harder to solve. You can't parse HTML with regex unless it's a set of specific circumstances due to how HTML markup is structured – Tom J Nowell Jun 24 '20 at 9:36
