Parsing HTML tables

N

Nicolas Pioupiou

Hi everybody,

I'm searching for a way to write a beautidull code which parse an HTML
table.

In fact, the table is dynamic.
It always have three columns but have randoms lines.

In each "line" (<tr></tr>) I want to extract the information inside the
colums <td></td>. And then, I create a new object with these
informations.

I done it by splitting my html source with the method split("<tr>") and
use regexp to extract what I want. But this solution do not satisfied
me. It's unmaintanable.

However, I'm pretty sure that I could do more clever code...

Is there anyone has an idea, a clue a thought ?

Thanks.
PS: English is not my native langage...

Use a real parser. Example:

#---
require 'nokogiri'

html = <<eohtml
<html>
<body>
<table>
<tr>
<td>One</td><td>Two</td><td>Three</td>
</tr>
</table>
</html>
eohtml

doc = Nokogiri::HTML(html)

doc.search('//tr').each do |line|
puts line.search('td/text()')
end

#---
Output:
One
Two
Three
