Hi again, I'm allways here to ask how to use regular expressions.
what I want now is to replace chars from a string with empty spaces

sample = "thi's is a tes<>%$#!|t"

what I want is use sample.sub(\['<>%$#!|]\,"")
and the outcome shoudl be

"this is a test"

But I only can replace the first occurence of the chars specified in the
reg exp

How can I replace all occurences?

Thnaks,

Use gsub instead of sub.

Will this work ?

sample = "thi's is a tes<>%$###!!!!!###!|t"

x = sample.gsub(/[\''<>%$#!\|]/,"")
puts x

Use gsub instead of sub.

You can find it in the docs: http://ruby-doc.org/

Hint: There are sub, sub!, gsub and gsub!.

Kind regards

But, wouldn't it be easier to do something like this?

sample = "thi's is a tes<>%$###!!!!!###!|t"
y = sample.delete("#!%<'>$|")
puts y

If you want, you could tell gsub to replace everything that is not a-z
or A-Z or a white space character

sample = "thi's is a tes<>%$#!|t"
sample.gsub(/[^a-zA-Z\s]/,"")
"this is a test"
