Why this code doesn't work?

Ruby

Hi,

I am trying to replace all html tags and spaces with “*” in a string.

I tried this code:

"as sd “.sub(/<[\s\S]?>| /,"”)

It just replaces the 1st occurance.

This code also doen’t work:

"as sd “.sub(/<[\s\S]?>| /){|s| "”}

How can I do that?

Thanks,
Alan

Try:

…gsub…

Hope that helps.

It’s also worth pointing out that [\s\S] means a character class
containing all whitespace and non whitespace characters–in other words:
everything. This is equivalent:

"as sd “.sub(/<.?>| /,"”)

which replaces [\s\S] with .

Also, if your tags could have line breaks in them, you can add ‘m’ (for
multiline) to the end of the regular expression literal and then . will
match newlines as well:

/regex/m

Oh, and if you replace that last space (after the pipe character) with
\s, then it will match tabs too (or any whitespace for that matter).
