Regular expression that detects all numbers (integer or float ) in any string ?

[paul_cardinale]

I don't believe it's possible to do what you want with a regex.  When you do a search for a regex, what gets returned is whatever portion of the input string matches the regex.  It will be an intact section of the input string; it will not be edited.  In other words, the search engine will not remove & discard pieces from the middle.

What are you really trying to do?

Why are the numbers coming in all mixed up with the other characters?

hi,

I try to extract just numbers from any String ?

Qwerty12,45n67kiol89,

i want in the output : 12456789

But why are you getting a string that has letters in it?  Where is this string coming from?

It's easyer to remove everything that is not a digit. If you want to keep the comma add it to the character class.
