Question

I have a text input that will be input like the following

7 - BMW 550i

If the user inputs this, how can i use a regular expression to remove all the content on the right of the dash character so all i am left with is the first numerical value.

I have tried this:

-?\\d+

But if like the example i gave it will get the end numbers.

Answer 1

This should work:

(\d+)\s*-

Use $1 to get your result.

For example, in Perl, use this:

my ($number) = ($str =~ /(\d+)\s*-/);
