title: New to XSLT - how to return text of span class in xml?
body: <p>I have the following XML:</p>
  
  <pre><code>    &lt;core:renderedItem&gt;
      &lt;span class="harvard_title"&gt;Whose Ecosystem is it Anyway: Private and Public Rights under New Approaches to Biodiversity Conservation&lt;/span&gt;
      '
      &lt;span&gt;
        &lt;em&gt;Journal of Human Rights and the Environment&lt;/em&gt;
      &lt;/span&gt;
      .
    &lt;/div&gt;
  </code></pre>
  
  <p>How do I get access to the text of span class="harvard_title" using xslt?  Ideally I would like to return just the text up to the colon "Whose Ecosystem is it Anyway"</p>
