hi,i want to prase the web
‘行情中心_网易财经’
there are 27 tables in the web,
i made a for loop to get every table in the web,
/home/pt/test/table0 is the output of tables[0],
/home/pt/test/table1 is the output of tables[1],
,
/home/pt/test/table26 is the output of tables[27],

here is my programme,

require ‘hpricot’
require ‘open-uri’
require ‘iconv’
data =
open(‘行情中心_网易财经’).read
html = Iconv.iconv(“UTF-8//IGNORE”,“GB2312//IGNORE”,data)
u8doc = Hpricot(html[0])
tables = u8doc.search(“table”)
i=tables.size
puts i
for j in 0…i-1
File.open(‘/home/pt/test/table’+j.to_s+‘.html’, ‘w’) {|f|
f.write(‘tables[’+j.to_s+‘]’.inner_html) }
end

Hi,

do you want something like this?:

require ‘hpricot’
require ‘open-uri’
require ‘iconv’

data =
open(‘http://quotes.money.163.com/corp/1034/code=601398.html’).read

html = Iconv.iconv(“UTF-8//IGNORE”,“GB2312//IGNORE”,data)

u8doc = Hpricot(html[0])

tables = u8doc.search(“table”)

i=tables.size

puts i

for j in 0…i do

output = File.new(“/Users/jbw/table” + j.to_s + “.html”, “w”)
output.puts tables[j]
output.close

end

think for your help
the right code is :
require ‘hpricot’
require ‘open-uri’
require ‘iconv’
data
=open(‘http://quotes.money.163.com/corp/1034/code=601398.html’).read
html = Iconv.iconv(“UTF-8//IGNORE”,“GB2312//IGNORE”,data)
u8doc = Hpricot(html[0])
tables = u8doc.search(“table”)
i=tables.size
for j in 0…i-1
output = File.new(“/home/pt/test/table” + j.to_s + “.html”, “w”)
output.puts tables[j].inner_html
output.close
end
i still have some problems:
1\when i got the table’s html,for example tables[2],
can i get row size or column size of the tables[2].
2\can i use array to load the data in the tables[2]??
