Cleaning up HTML code from WordPress database - 03/11/2017 08:17 EDT

I am caching products from Ebay using ebay API in my multi-sites WordPress. I have hired a developer to develop a bot that cache for me the products. In some cases I get products cached with HTML see the link blow to the page with the code this is what the bot has cached. [login to view URL] and this is from Ebay [login to view URL] I have different examples to show you what the problem is [login to view URL] that was from the bot [login to view URL] that was from Ebay I want to cleanup the page from this code which I get regular because of the advertising that Ebay in some pages have and also from the menu of the seller shop. The bot get the part of the page and store it in the database like this see the attachment I want script or query to remove the code that appear on the page as you have seen this will run continuous because the bot is always running and cache of updating. MAX BID IS $50 HIGHER BID WILL BE REMOVED AT ONCE
