Re: replace string

You forgot to mention what's not working

In your case it is a missing line

__DATA__
[download]

right before the example data, and a regex you might change to

s/<([^>]*)>/\{$1\}\n/g;
[download]

or alternatively

s/<(.*?)>/\{$1\}\n/g;
[download]

Note that this is probably still short of what you want, since you seem to need to throw away ending tags. In that case you could add '/' to the character class above and throw away the ending tags in a second regex

I think this is a better regex to solve this problem: `s!\s<\s(/?)\s(\w+)\s>\s!$1?"\n":"\n\{$2\}\n"!ge;` [download] because `</ttl>` should not appear (from the example's output) and there is a problem with extra white spaces surrounding and inside tags. Also, there was no info on what to do if there is more text after a closing tag, so I guessed that a new line must be inserted. But that regex will generate extra empty lines if a data line starts with a tag. Changing to this should do the trick: `s!\s<\s(/?)\s(\w+)\s>\s!$1?"\n":"\n\{$2\}\n"!ge and s!^\n!!;` [download] Please note that I kept the `\w+` for the capture, asuming that only alphanumerics are admited as tags.
