Website scrapping tool using wordpress custom plugin part 7 ( delete operation )

Web Scraping is a technique used to extract large amounts of data from websites extracted and saved them to a local file in your computer or to a database or can be used as API. Data displayed by most websites can be viewed by using a web browser only. They do not offer the functionality to save a copy of this data for use. Thus the only option is to copy and paste the selected data that is required, which in reality, is a very tedious job and may take hours complete. In other terms, Web Scraping is the technique of automating such a process, in place of manual work, the Web Scraping software performs the same task within seconds.
