Re: Hpricot - strip out images and show first x words

Hi 7stud, thanks.

This seems to return the first 25 words of every paragraph?  Maybe i'm
not returning the right thing from the method though...here's how i
wrapped up your code (in lede2 method) and mine (in lede method):

   def lede(word_count = 25)
      doc = self.hpricot_body
      #wipe images
      doc.search("img").remove
      paras = doc.search("//p")
      text = ""
      while paras.size > 0 && text.split(" ").size < word_count
        text += paras.shift.to_html
      end
      if (arr = text.split(" ")).size > 25
        return arr[0..24].join(" ") + " ..."
      else
        return arr.join(" ")
      end
    end

    def lede2(word_count = 25)
      doc = self.hpricot_body
      results = []
      paras = doc.search("//p")
      paras.each do |para|
        para.search("img").remove
        text = para.inner_html
        words = text.split()
        if words.length <= word_count
          results << words.join(" ")
        else
          results << "#{words[0, word_count].join(" ")}..."
        end
      end
      results.collect{|text| "<p>#{text}</p>"}.join
    end

And here are the results of calling each method on the same post:  first
i show the html content (body_rendered) that we use in the lede methods.

nine British new media innovators and I arrived at the Foreign Office 
for a meeting with the Foreign Secretary, <a

MP</strong></a>, to discuss how government can support this important 
sector. Over breakfast, the delegates, Mr Milliband, Foreign Office 
Minister <strong>Gillian Merron</strong> and <strong>Sir Andrew 
Cahn</strong> explored this key area for opportunities in wealth 
creation, and to understand how the public sector can find new ways of 
working using new media tools.</p>\n<p><span></span>The biggest 
challenge raised by the companies was the apparent dearth of funding 
opportunities for new start-ups in this economic climate and beyond. 
There are few investors in the UK outside London, and most companies 
seek funding from US sources.</p>\n<p>Admittedly, the digital sector has 
a stronger ability to weather the storm than other market sectors; after 
the bubble of 2000 burst, start-ups regrouped and re-emerged from the 
ashes as <a

2.0\342\200\262</a> in 2005, aiming to generate businesses with sturdy 
and market-resilient plans that can face inclement weather. However, 
delegates called for funds to bridge the gap between 
\302\24310-\302\243250k, and to support training programmes for new 
talent into the digital and creative industries.</p>\n<p>The Foreign 
Secretary, who has a track record as a blogger and new media enthusiast, 
also wanted to explore with his visitors the contribution new 
technologies can make to diplomacy and international 
problem-solving.</p>\n<p>British new media developers excel at building 
social entrepreneurial applications, ensuring that their social 
networking, social software (e.g., blogs) and other social systems 
(e.g., search, data visualisation) work to ensure participation in the 
community.</p>\n<p>New media leverages communities based on 
commonalities, rather than proximity, encouraging participation on an 
equal playing field. It has been crucial in breaking down international 
and social barriers, exposing participants first-hand to news and news 
sources, encouraging them to engage with people of different religions, 
cultures and creeds, of different abilities and languages. It is 
transforming the way our children learn, the way our teachers teach and 
the way we do business. In short, it has put the person back into the 
technology, lowering the barriers for knowledge and sharing.</p>\n<p>Yet 
the challenge remains in opening up policy debates in such a way as they 
mobilise the many-to-many networks which new media supports. Delegates 
suggested using gaming technologies to break down boundaries of 
participation and communication, and to open up public assets to 
communities who may be able to offer better solutions than those that 
have come before.</p>\n<p>The Business Breakfast was organised by the <a
