Re: Finding intermediate token in a string

[Austin Einter <austin.einter@...>]

Hi Enrico Colombini

Your suggestion worked fine. Thanks.

The final function looks as

function calculate_content_length(msg, length)
    local lens = msg:match('Content%-Length%s*:%s+(%d+)%s+')
    local len = 0
    if lens then -- gotcha Content-length
       len = tonumber(lens)
    end
    return len
end

Thanks

Austin

I think it should not be anchored: he said "input string might have some data before or after of given example values".

To Austin: try removing the leading '^' and the trailing '$' from the pattern string.
