IsMatch function not functioning correctly

Currently building a powerapp where users need to input a url to a document hosted in SharePoint. I need to validate that is it a URL the user is inputting, however, I'm having some trouble and found the IsMatch function doesn't appear to be working correctly.

 

I'm using the example from the microsoft reference page here: https://powerapps.microsoft.com/en-us/tutorials/function-ismatch/

According to it the following expression should show as true:

IsMatch( "http://microsoft.com", "(ht|f)tp(s?):\/\/[0-9a-zA-Z]([-.\w][0-9a-zA-Z])(:(0-9))(\/?)([a-zA-Z0-9-.\?\,\'\/\+&%\$#_]*)?" )

 

However, when i apply this as the Text property of a label, it resolves as false (screenshot below).

Am I missing something here or is the function broken? Cheers

The documentaiton has been corrected.  Our documentaiton is written in Markdown which interprets * as a special character and was effectively eating those characters in what you read.  They have now been properly escaped and the URL validation example is working again.

Sorry, there is a typo in the documentation so the regex got mangled. Those that can read regex (ie not me!) are fixing it, thanks for the report.

It looks like this is still an issue. I copied the info straight off the page and it is showing as false.
