ok, been going on this for an hour now, and can not find a solution

I want to find all content between ` tags in a string and replace
the content of these with new formatted content. Any suggestions why the
following code is not working?`

self.content = self.content.gsub(/`(.*?)</code>/, ‘new content’)`

Cheers  
Josh

Nope, because it is working:
irb(main):026:0> “This is stuff”.gsub(/(.*?)</
code>/, ‘new content’)
=> “This is new content”

You need to provide more details and code if you’re experiencing
something different.

Hi,

Last comment got me thinking and after testing of the code, and have  
found that it breaks if there is a new line ‘\n’ within the `. Does
anyone know how to get the (.*?) to accept new lines ( \n )`

`
thanks

you can set a multiline regexp pattern by adding m after the pattern,
like in /.*/m
