how to use regex function in Clay
You can use regex in Clay primarily through the "Scrape Website" action by using the "Extract Custom Regex" field. This allows you to define patterns to extract specific data from websites.
For example, if you wanted to extract all Wikipedia links from a website, you could use this regex pattern: LBKShttps?://([a-z]{2,3}.)?[[wikipedia.org/wiki](http://wikipedia.org/wiki)]([https://wikipedia.org/wiki](https://wikipedia.org/wiki))/[a-zA-Z0-9_-]**LBKS
Clay also offers other actions that leverage pattern matching:
** "Find Keywords" action to search for specific terms in text
** "Extract Values from Data" to pull specific information from datasets
** "Extract URLs and Emails from Text" to automatically identify and extract these elements
When creating your regex pattern, make sure it accurately describes the data structure you're trying to match.
