Looking at input/feed_0/article_0/index.html from your attachment, I see

<div id="hatFacebook" style="border: none;">&lt;h4&gt;WSJ on Facebook&lt;/h4&gt;&lt;div style=&quot;border: none; padding: 2px 3px;&quot; class=&quot;fb-like&quot; data-href=&quot;http://www.facebook.com/wsj&quot; data-send=&quot;false&quot; data-layout=&quot;button_count&quot; data-width=&quot;250&quot; data-show-faces=&quot;false&quot; data-action=&quot;recommend&quot;&gt;&lt;/div&gt;</div>

this is most likely because the html parser incorrectly parsed something. So fixing the html in preprocess_raw_html might do the trick. The easiest way to fix it, is like this

def preprocess_raw_html(self, html, url):
     import html5lib
     root = html5lib.parse(html)
     from lxml import etree
     return etree.tostring(root, encoding=unicode)

Alternatively you can use regexps to nuke <meta>, <script>, <style> tags and comments which are most often the cause of parse errors.
