    text
    copied!<p>I'm having troubles parsing inside a for loop of only the inner_html that I have found. I want to use XPath again inside that content only. I'm new to ruby so better solutions are on the table.</p> <pre><code>#!/usr/bin/ruby -w require 'rubygems' require 'nokogiri' page1 = Nokogiri::HTML(open('mycontacts.html')) # Search for nodes by xpath page1.xpath('//html/body/form/div[2]/span/table/tbody/tr').each do |row| #puts a_tag.content puts "new row" row_html = row.inner_html puts row_html puts "" name = row_html.xpath("/td[1]").text puts "name is " + name end </code></pre> <p>My output of each row in the for loop is something like:</p> <pre><code>new row &lt;th&gt;First Name&lt;/th&gt; &lt;th&gt;Last Name&lt;/th&gt; &lt;th&gt;Phone&lt;/th&gt; </code></pre> <p>Here's the error that I'm getting:</p> <p>screen-scraper.rb:20:in <code>block in &lt;main&gt;': undefined method</code>xpath' for # (NoMethodError)</p> <p>I want to parse each tr and get data like: Barney Rubble, Fred Flintstone</p> <pre><code>&lt;table&gt; &lt;tbody&gt; &lt;tr&gt; &lt;th&gt;First Name&lt;/th&gt; &lt;th&gt;Last Name&lt;/th&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Fred&lt;/td&gt; &lt;td&gt;Flintstone&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Barney&lt;/td&gt; &lt;td&gt;Rubble&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; </code></pre> <p>I'm open to suggestions. I was thinking it's easier to parse only the inner_html inside the for loop, but if there's an easier way to get at the node within the for loop, that would work as well.</p> <p>Thanks....</p>
