问题 So I upgraded a Rails app from 3.0 to 4.0 last week, and ever since I've been getting strange errors that seem to point to random places that I haven't changed, and I can't reproduce them. One such error is like this: NoMethodError: undefined method `global_endpoint?' for AWS::S3:Class [GEM_ROOT]/gems/aws-sdk-1.46.0/lib/aws/core/configuration.rb:441 /gems/aws-sdk-1.46.0/lib/aws/core/configuration.rb:441 in "block in add_service" /gems/aws-sdk-1.46.0/lib/aws/core/configuration.rb:361 in "call"

问题 I have to clean up a Nokogiri::HTML::DocumentFragment document (remove comment nodes and text nodes which contain whitespace only). Here's an example: html = "<p>paragraph</p><!-- comment --><p>paragraph</p> <p>paragraph</p>" doc = Nokogiri::HTML::DocumentFragment.parse html The document fragment looks as you'd expect: #(DocumentFragment:0x3fc65f9f5870 { name = "#document-fragment", children = [ #(Element:0x3fc65f9f5064 { name = "p", children = [ #(Text "paragraph")] }), #(Comment " comment "

Here's some sample HTML of what I'm working with: <div class="date"> <span>Today</span> </div> <div class="random"></div> <div class="preferred"></div> <div class="preferred"></div> <div class="preferred"></div> <div class="random"></div>

Nokogiri producing different results on heroku?

问题 I'm having a very strange problem and I'd appreciate help tracking it down. I'm using the nokogiri gem to parse some html, and I am parsing a file which has a weird character in it. Not entirely sure what this character is, in vim it shows as ^Q. On my own computer, everything works fine, however on heroku it inserts a </body></html><html> when it hits the character and selectors only return the elements before the weird character. To illustrate: Nokogiri::HTML( open("http://thoms.net.nz/e2

How can I detect errors in an HTML document fragment with Ruby?

由 痴心易碎 提交于 2019-12-11 01:36:14
问题 I'm collecting some HTML formatted content from a web form. Before saving this HTML content, I'd like to do a quick sanity check on it to make sure it looks well-formed (no unclosed tags, no invalid markup). Using Ruby and/or with any popular gems, can I check an HTML fragment string like: <p>foo</p><h1>Unclosed H1<p>bar</p> and discover things like the unclosed h1 tag? I thought Nokogiri would come to my rescue here, but no: >> Nokogiri::HTML::DocumentFragment.parse("<p>foo</p><h1>Unclosed
