RegExp problem


#1

I need to match a block of text as follows

Discard all lines which begin with //
Capture all lines in between as single strings

So

// section 1
bit

bit more

// section 2

more stuff

// section 3

and yet more

Should yeild 3 strings:
[ bit\n\nbit more\n\n]
[\n\n\n more stuff\n\n]
[\n\n\nand yet more\n]

Can anyone help?

I’ve tried:

builds = s.scan(%r[\n//[^\n]\n([^\n]\n)+?]m)

but this yields
[ bit]
[\n]
[\n]

how can I make the group capture more than a line?

s.split(%r{//.*})
=> ["", “\n bit\n\nbit more\n\n”, “\n\n\n more stuff\n\n”, “\n\n\nand
yet more\n\n”]

Close enough?

Try something like this.
You can clean it up as necessary.

s = “// section 1\nbit\n\nbit more\n\n// section 2\n\nmore stuff\n\n//
section 3\n\nand yet more”
s.split(///\s+section\s+\d+/).each {|x| p x}
