Nokogiri in Ruby 2.0

由 这一生的挚爱 提交于 2019-12-03 18:13:16
When I require 'nokogiri' in Ruby 2.0, it has a error `require': cannot load such file -- nokogiri/2.0/nokogiri (LoadError) Is nokogiri not supporting Ruby 2.0 yet? I can see nokogiri in gem list Mike Dalessio Ruby 2.0 support is not yet available for Windows. Follow along here for updates: Yes, it works fine: RUBY_VERSION # => "2.0.0" require 'nokogiri' doc = Nokogiri::HTML('<html><body><p>foo</p></body></html>') doc.at('p').text # => "foo" Nokogiri now support Ruby 2.0, even on Windows, see HERE 来源： https://stackoverflow.com/questions/15332416/nokogiri-in-ruby-2-0

How can I get Nokogiri to parse and return an XML document?

Here's a sample of some oddness: #!/usr/bin/ruby require 'rubygems' require 'open-uri' require 'nokogiri' print "without read: ", Nokogiri(open('http://weblog.rubyonrails.org/')).class, "\n" print "with read: ", Nokogiri(open('http://weblog.rubyonrails.org/').read).class, "\n" Running this returns: without read: Nokogiri::XML::Document with read: Nokogiri::HTML::Document Without the read returns XML, and with it is HTML? The web page is defined as "XHTML transitional", so at first I thought Nokogiri must have been reading OpenURI's "content-type" from the stream, but that returns 'text/html' :

XPath to select between two HTML comments?

由 Deadly 提交于 2019-12-03 14:31:44
问题 I have a big HTML page. But I want to select certain nodes using Xpath: <html> ........ <!-- begin content --> <div>some text</div> <div><p>Some more elements</p></div> <!-- end content --> ....... </html> I can select HTML after the <!-- begin content --> using: "//comment()[. = ' begin content ']/following::*" Also I can select HTML before the <!-- end content --> using: "//comment()[. = ' end content ']/preceding::*" But do I have to have XPath to select all the HTML between the two

Modifying text inside html nodes - nokogiri

由 最后都变了- 提交于 2019-12-03 13:29:15
Let's say i have the following HTML: <ul><li>Bullet 1.</li> <li>Bullet 2.</li> <li>Bullet 3.</li> <li>Bullet 4.</li> <li>Bullet 5.</li></ul> What I wish to do with it, is replace any periods, question marks or exclamation marks with itself and a trailing asterisk, that is inside an HTML node, then convert back to HTML. So the result would be: <ul><li>Bullet 1.*</li> <li>Bullet 2.*</li> <li>Bullet 3.*</li> <li>Bullet 4.*</li> <li>Bullet 5.*</li></ul> I've been messing around with this a bit in IRB, but can't quite figure it out. here's the code i have: html = "<ul><li>Bullet 1.</li> <li>Bullet

Parsing Large XML files w/ Ruby & Nokogiri

由 北城余情 提交于 2019-12-03 12:59:06
I have a large XML file (about 10K rows) I need to parse regularly that is in this format: <summarysection> <totalcount>10000</totalcount> </summarysection> <items> <item> <cat>Category</cat> <name>Name 1</name> <value>Val 1</value> </item> ...... 10,000 more times </items> What I'd like to do is parse each of the individual nodes using nokogiri to count the amount of items in one category. Then, I'd like to subtract that number from the total_count to get an ouput that reads "Count of Interest_Category: n, Count of All Else: z". This is my code now: #!/usr/bin/ruby require 'rubygems' require

set tag attribute and add plain text content to the tag using nokogiri builder (ruby)

由 寵の児 提交于 2019-12-03 11:42:56
问题 I am trying to build XML using Nokogiri with some tags that have both attributes and plain text inside the tag. So I am trying to get to this: <?xml version="1.0"?> <Transaction requestName="OrderRequest"> <Option b="hive">hello</Option> </Transaction> Using builder I have this: builder = Nokogiri::XML::Builder.new { |xml| xml.Transaction("requestName" => "OrderRequest") do xml.Option("b" => "hive").text("hello") end } which renders to: <Transaction requestName="OrderRequest"> <Option b="hive
