Hi,
I'm looking the way of searching an string in a HTML file given the URL.
The parameter will be "<span>value</span>" ... it has to be that
format, exactly.
I'm trying with Hpricot (http://code.whytheluckystiff.net/hpricot)
which is very powerfull ... but it searches for elements, so i only
can pass the value of the SPAN .. no the whole string.
anyway of searching for an string in a html file given the URL?
thanks,
Jean
Will this do it? (I have not run it, so there may be errors.)
require 'open-uri'
uri = URI.parse('http://whatever')
data = uri.read
data.scan('<sub>whatever</sub>')

Hi Jean,
Here is my version of it:
require 'open-uri'
# this returns true if the string is found
open('http://whatever').find { |line| line.match('<span>value</span>') }
!= nil

Hello there,
I am a newbie to Ruby and Watir.
Currently, me trying to extract a parameter from the html page. But the
Value I am trying to extract keeps changing and depends on the input.
Here is the piece of code I tried which did not work...
require 'open-uri'
require'watir'
require 'fileutils'
require 'net/http'
d_term = "Banks"
url1 = Whatever...
MT = 'Search '+'<b>'+d_term.chomp+'</b>'
open(url1).find {|line|
if line.match(MT)
foo = File.open("c://abc.txt", "a+")
foo.puts ("Found: " + line)
foo.close()
end
Any help greatly appreciated.
Thanks,
Madu

if (open(url1).find { |line| line.match(MT) } != nil)
foo = File.open("c://abc.txt", "a+")
foo.puts ("Found: " + line)
foo.close()

require 'open-uri'
require'watir'
require 'fileutils'
require 'net/http'
Madu,
The error you have is coming out of Watir which unfortunately I have no
experience with.
For the code sample you posted, you only need to include open-uri.
watir, fileutils and net/http are unused by your code sample.
As Jean proposed, I suggest you debug your application by breaking it in
smaller pieces.

dont know those errors ..., you can troubleshoot ...
make sure that "open(url1)" it is not givin you an error .. If that
line is giving you an error, it means the web site doesn't exist or
you are including the open-uri code ( include 'open-uri.rb (i believe
is the line)
regards,
Jean
