Re: Reading substrings

[Jose Marin <jose_marin2@...>]

Warning: need error checking, and change the BASIC
style variables!


function extractContents(s, pattern1, pattern2)
local a, b, d, c

	a, b = string.find (s, pattern1 )
	c, d = string.find (s, pattern2 )

	return string.sub(s, b+1, c-1)
end


To print the title of a html page (loaded on the
'page' variable):

print( extractContents(page, "<TITLE>", "</TITLE>"))

Hope this could be useful to someone...
