this should do the trick

Code: Select all

regsub -all {[^0-9]} $text {} newtext

Also you can use regular expressions for the same thing.

Code: Select all

    set countnumbers [regexp -all {[0-9]} $text]

The variable $countnumbers will be a value of the counted
numbers in the text.

Take a look at this previous thread and the examples
you can get an idea.

That's not what Friischling asked for.

regexp = match a regular expression against a string
regsub = perform substitutions based on regular expression pattern matching

Yeah sorry, that code I gave was to count
the numbers in a text, and place the total value
of numbers in a variable.

However, the link I supplied for reference and examples
is correct, and you can get an idea from that.

Who said that the code you have pasted is not correct? It is but is not what Friischling was looking for.
