Asp Forum - Another RegExp question

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

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"

No, I didn't.

False news. Some say he moved to India with Magdalena, had a slew of
kids and died of old age practicing Buddhism.

My religion is much deeper than that. We take charge of our own destiny
and don't need a fairy tale about how someone died for our sins.

Yeah, we know, and it's false.

You got it.

No, unlike you, he's claiming that even atheists, if they do good, will
be saved by your make believe Jesus. "Good", BTW, is a subjective
judgment and therefore meaningless.

The only real problems are avarice, anger and stupidity.

Don't put words in my mouth that aren't there.

I don't need saving by anyone. I take responsibility for my own life and
don't rely on magical fairy tales like you do.

Care to reply to the other points I made or merely scurry under that
rock of yours like you do so many times.
