You can now create and use regular expression (regex) entities in your Power Virtual Agents bot, making it possible to identify information from a user’s input that follows a certain logical pattern.<\/p>\n\n\n\n
Regular expression (regex) entities let you define logical patterns that you can use to match and extract information from an input. Regex entities are great for complex pattern matching against a user’s input, or if you need to allow for specific variations in how a user might format or enter their input in a conversation. For example, you could use a regex entity to identify items such as a tracking ID, a license number, a credit card number, or an IP address from a string the user enters into the bot.<\/p>\n\n\n For more information on using entities in Power Virtual Agents, refer to documentation here: Use entities and slot filling<\/a>.<\/p>\n\n\n\n Go ahead and try this feature at powerva.microsoft.com<\/a>.
