If you are having a string with special characters and want's to remove/replace them then you can use regex for that. Use this code: Regex.
When you want to search and replace specific patterns of text, use regular expressions. They can help you in pattern matching, parsing, filtering of results, and so on. Once you learn the regex syntax, you can use it for almost any language. Press Ctrl+R to open the search and replace pane.
Replace ^(?!.*pad.*).+$ with empty string
