Hi, does anyone know how to get this Regex string to work in gambas interpreter?   ops:
( string is a suggested URL match! ?)

Thanks,

It is because regex escape characters are different to gambas.

you have to use 2 backslashes \ for each regex specific escape.

2 backslashes \ in gambas is \   so for example \/ that you may use in regex but not gambas has to be input as \/

Also all the other chars like \w will have to be \w ,  \$ \+ and so on.

Thanks Bruce,
    Interpreter is happy with the expression string now all '\' are '\'  
But am getting this error in the Regexp.Match line of code:-

Will try other suggested (online) web URL-match expressions, but any from the forum gratefully received.

Thanks,

 Sorry Chris I cannot help further , i know very little about complex regex expressions.

I'd use something simpler like Like

If webURL Like "{http,https,ftp}://*" Then

Although I don't really know what exactly you are checking for.

Hi, re. the above issues, I just thought this might be useful if you're developing a straight forward Webview …

I needed a view and URL textbox that the user could enter or paste the URL of a webpage/download. Also wanted the input value to be compliant with URI syntax before the web request is submitted to the webView.url property.

After a few attempts, along with Bruce's help with string escape characters, I came up with the following code:-
The Regex match-string used here was the most reliable - and error-free - that I could find online. (scoured stackoverflow.com,
but there are many other sites with ideas for 'best' URI Regex - note: some raise errors, so maybe use Try command!).


Hope this helpful to folk.
