[Skype] Regular expression not working to find email address in chat message?

Bot Info

• SDK Platform: Node.js
• SDK Version: Bot Builder 3.13.1 with Botkit 0.6.7
• Active Channels: Skype, Messenger, Telegram and Web
• Deployment Environment: Azure Bot Service and Azure App Service

Issue Description

I built a bot using Bot Framework (node.js) with four connected channels (Messenger, Telegram, Skype and Web). At any moment the bot validates an inputted email address using a regular expression like this below:

/^[-a-z0-9~!$%^&*_=+}{\'?]+(\.[-a-z0-9~!$%^&*_=+}{\'?]+)*@([a-z0-9_][-a-z0-9_]*(\.[-a-z0-9_]+)*\.(aero|arpa|biz|com|coop|edu|gov|info|int|mil|museum|name|net|org|pro|travel|mobi|[a-z][a-z])|([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}))(:[0-9]{1,5})?$/i

It is working properly on all channels, except the Skype. E.g: [e-mail] match with this regex but on Skype channel it doesn’t happens.

Code Example

emailRegex.test([e-mail]);

Expected Behavior

The email address [e-mail] should match with the regex above.

Actual Results

Skype channel just ignore the step with the regex validation.

Hi @gcfabri - You need to verify that the content being returned by Skype channel is actually a plain-text email address. Sometimes Skype wraps email addresses in HTML tags, so you would need to adjust your RegEx accordingly.

On Skype channel you need to check for: <a href="mailto:[e-mail]">[e-mail]</a>

Hi All,

I was facing the same issue and I found the below regular express which resolved my issue.

@“\b(?!mailto:)([\w-]+(.[\w-]+)@([a-z0-9-]+(.[a-z0-9-]+)?.[a-z]{2,6}|(\d{1,3}.){3}\d{1,3})(:\d{4})?)”

Thanks
