RE: Reading substrings

["Denis Povshedny" <denikin@...>]

Hello Jose!

It's Just a suggestion.

I think in your particular case it is important to use something as

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

to be able to parse <> tags written in any case. Of course, if you do
not generate these html by yourself :)

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...
