Hpricot, Get All Text From Document
I have just started learning Ruby. Very cool language, liking it a lot. I am using the very handy Hpricot HTML parser. What I am looking to do is grab all the text from the page,
Solution 1:
You can do this using the XPath text() selector.
require'hpricot'require'open-uri'
doc = open("http://stackoverflow.com/") { |f| Hpricot(f) }
text = (doc/"//*/text()") # array of text values
puts text.join("\n")
However this is a fair expensive operation. A better solution might be available.
Solution 2:
You might want to try inner_text.
Like this:
h = Hpricot("<html><body><ahref='http://yoursite.com?utm=trackmeplease'>http://yoursite.com</a> is <strong>awesome</strong>")
puts h.inner_text
http://yoursite.com is awesome
Solution 3:
@weppos: This will be bit better:
text = doc/"//p|div/text()"# array of text values
