Strip text from HTML document using Ruby

由 老子叫甜甜 提交于 2019-11-29 19:15:14
问题 There are lots of examples of how to strip HTML tags from a document using Ruby, Hpricot and Nokogiri have inner_text methods that remove all HTML for you easily and quickly. What I am trying to do is the opposite, remove all the text from an HTML document, leaving just the tags and their attributes. I considered looping through the document setting inner_html to nil but then really you'd have to do this in reverse as the first element (root) has an inner_html of the entire rest of the

Find and replace entire HTML nodes with Nokogiri

问题 i have an HTML, that should be transformed, having some tags replaced with another tags. I don't know about these tags, because they will come from db. So, set_attribute or name methods of Nokogiri are not suitable for me. I need to do it, in a way, like in this pseudo-code: def preprocess_content doc = Nokogiri::HTML( self.content ) doc.css("div.to-replace").each do |div| # "get_html_text" will obtain HTML from db. It can be anything, even another tags, tag groups etc. div.replace self.get

trying to get content inside cdata tags in xml file using nokogiri

I have seen several things on this, but nothing has seemed to work so far. I am parsing an xml via a url using nokogiri on rails 3 ruby 1.9.2. A snippet of the xml looks like this: <NewsLineText> <![CDATA[ Anna Kendrick is ''obsessed'' with 'Game of Thrones' and loves to cook, particularly creme brulee. ]]> </NewsLineText> I am trying to parse this out to get the text associated with the NewsLineText r = node.at_xpath('.//newslinetext') if node.at_xpath('.//newslinetext') s = node.at_xpath('.//newslinetext').text if node.at_xpath('.//newslinetext') t = node.at_xpath('.//newslinetext').content

Nokogiri and Xpath: find all text between two tags

由 风格不统一 提交于 2019-11-29 11:25:18
I'm not sure if it's a matter of syntax or differences in versions but I can't seem to figure this out. I want to take data that is inside a (non-closing) td from the h2 tag to the h3 tag. Here is what the HTML would look like. <td valign="top" width="350"> <br><h2>NameIWant</h2><br> <br>Town<br> PhoneNumber<br> <a href="mailto:emailIwant@nowhere.com" class="links">emailIwant@nowhere.com</a> <br> <a href="http://websiteIwant.com" class="links">websiteIwant.com</a> <br><br> <br><img src="images/spacer.gif"/><br> <h3><b>I want to stop before this!</b></h3> Lorem Ipsum Yadda Yadda<br> <img src=

Using Nokogiri to Split Content on BR tags

由 我的梦境 提交于 2019-11-29 10:45:22
I have a snippet of code im trying to parse with nokogiri that looks like this: <td class="j"> <a title="title text1" href="http://link1.com">Link 1</a> (info1), Blah 1,<br> <a title="title text2" href="http://link2.com">Link 2</a> (info1), Blah 1,<br> <a title="title text2" href="http://link3.com">Link 3</a> (info2), Blah 1 Foo 2,<br> </td> I have access to the source of the td.j using something like this: data_items = doc.css("td.j") My goal is to split each of those lines up into an array of hashes. The only logical splitting point i can see is to split on the BRs and then use some regex on

Nokogiri: Select content between element A and B

由 对着背影说爱祢 提交于 2019-11-29 10:18:49
问题 What's the smartest way to have Nokogiri select all content between the start and the stop element (including start-/stop-element)? Check example code below to understand what I'm looking for: require 'rubygems' require 'nokogiri' value = Nokogiri::HTML.parse(<<-HTML_END) "<html> <body> <p id='para-1'>A</p> <div class='block' id='X1'> <p class="this">Foo</p> <p id='para-2'>B</p> </div> <p id='para-3'>C</p> <p class="that">Bar</p> <p id='para-4'>D</p> <p id='para-5'>E</p> <div class='block' id

Nokogiri: Searching for <div> using XPath

由 怎甘沉沦 提交于 2019-11-29 07:33:05
I use Nokogiri (Rubygem) css search to look for certain <div> inside my html. It looks like Nokogiri's css search doesn't like regex. I would like to switch to Nokogiri's xpath search as this seems to support regex in search strings. How do I implement the (pseudo) css search mentioned below in an xpath search? require 'rubygems' require 'nokogiri' value = Nokogiri::HTML.parse(<<-HTML_END) "<html> <body> <p id='para-1'>A</p> <p id='para-22'>B</p> <h1>Bla</h1> <p id='para-3'>C</p> <p id='para-4'>D</p> <div class="foo" id="eq-1_bl-1"> <p id='para-5'>3</p> </div> </body> </html>" HTML_END # my

Creating an XML document with a namespaced root element with Nokogiri builder

由 我们两清 提交于 2019-11-29 07:10:05
问题 I'm implementing an exporter for an XML data format that requires namespaces. I'm using the Nokogiri XML Builder (version 1.4.0) to do this. However, I can't get Nokogiri to create a root node with a namespace. This works: Nokogiri::XML::Builder.new { |xml| xml.root('xmlns:foobar' => 'my-ns-url') }.to_xml <?xml version="1.0"?> <root xmlns:foobar="my-ns-url"/> As does this: Nokogiri::XML::Builder.new do |xml| xml.root('xmlns:foobar' => 'my-ns-url') { xml['foobar'].child } end.to_xml <?xml

Nokogiri to_xml without carriage returns

问题 I'm currently using the Nokogiri::XML::Builder class to construct an XML document, then calling .to_xml on it. The resulting string always contains a bunch of spaces, linefeeds and carriage returns in between the nodes, and I can't for the life of me figure out how to get rid of them. Here's an example: b = Nokogiri::XML::Builder.new do |xml| xml.root do xml.text("Value") end end b.to_xml This results in the following: <?xml version="1.0"?> <root>Value</root> What I want is this (notice the
