Nokogiri adds characters during parsing on Heroku

由 血红的双手。 提交于 2019-12-06 16:12:56
It seems like Nokogiri has a problem with UTF-8 conversion of the nbsp character. I've gathered this is an issue related to LibXML2. Nokogiri recommends upgrading LibXML2 to 2.7.7 instead of 2.7.6 that's running on Heroku. Anyone know how I can use LibXML2 2.7.7 (or higher) on Heroku? The problem is as follows -- doc = Nokogiri::HTML("<html><p>Hi Hello</p></html>") doc.inner_html => "<html><body><p>Hi Hello</p></body></html>" doc.inner_html = "<p>Hello World</p>" => "<p>Hello World</p>" doc.inner_html => "<p>Hello World</p>" Looks like this is related: https://github.com/sparklemotion

Use XPath to group siblings from an HTML/XML document?

由 ☆樱花仙子☆ 提交于 2019-12-06 15:32:41
I want to transform an HTML or XML document by grouping previously ungrouped sibling nodes. For example, I want to take the following fragment: <h2>Header</h2> <p>First paragraph</p> <p>Second paragraph</p> <h2>Second header</h2> <p>Third paragraph</p> <p>Fourth paragraph</p> Into this: <section> <h2>Header</h2> <p>First paragraph</p> <p>Second paragraph</p> </section> <section> <h2>Second header</h2> <p>Third paragraph</p> <p>Fourth paragraph</p> </section> Is this possible using simple Xpath selectors and an XML parser like Nokogiri? Or do I need to implement a SAX parser for this task?

I'm using Nokogiri to parse XML. doc = Nokogiri::XML("http://www.enhancetv.com.au/tvguide/rss/melbournerss.php") I wasn't sure how to actually retrieve node values correctly.

Is there a way to select all the contents of a node?

Is there a way to select all the contents of a node in Nokogiri? <root> <element>this is <hi>the content</hi> of my æøå element</element> </root> The result of getting the content of /root/element should be: this is <hi>the content</hi> of my æøå element Edit: It seems like the solution is simply to use myElement.inner_html() . The problem I had was in fact that I was relying on an old version of libxml2, which escaped all the special characters. shingara Nokogiri.parse('<root><element>this is <hi>the content</hi> of my element</element></root>').css('element').inner_html If you want escape

Nokogiri XML import feed organisation?

由 Deadly 提交于 2019-12-06 14:40:49
问题 I have built a site that relies on an XML feed that I currently parse with Nokogiri. Everything works fine and dandy although I have all the code currently within my Admin controller so I can actually invoke the import via a URL i.e. /admin/import/ . I can't help but think that this doesn't belong in the controller. Is there a better way to do this, i.e. move the code into a stand alone import.rb file so it is only accessible from the console? If so where would I need to put this file, in the

问题 I'm working on Michael Hartl's RoR tutorials. I'm on chapter 3. Unfortunately, copy and pasting the gem files won't work for me, but I figured out which gem is the problem. It's the capybara gem. I've commented it out and continued the tutorial, but I'm at the point where I need to use the gem. Here is an example $bundle update giving me an error: $ bundle update Fetching gem metadata from https://rubygems.org/......... (Removed a bunch of text) Building nokogiri using system libraries.

How can I get the values of the attributes? require

问题 i need a way to run following nokogiri script #parser.rb require 'nokogiri' def parseit() //... end and call the parseit() while running below main.rb in jruby #main.rb require 'parser' parseit() Of course the problem is jruby cannot find 'nokogiri' as I have not installed it aka nokogiri-java via jruby -S gem install nokogiri The reason is there is some bug I found in nokogiri running under Jruby, so I have only installed nokogiri on Ruby not Jruby.
