title: XSLT: escaping double quote
body: <p>I have XSLT code like:</p>
  
  <pre><code>&lt;xsl:if test="product_name='3" Magnifier'"&gt;
               &lt;attribute name="Business Unit"&gt;
               Consumer
               &lt;/attribute&gt;   
  &lt;/xsl:if&gt;
  </code></pre>
  
  <p>the value <strong>3" Magnifier</strong> (has quote), I couldn't compare it with <strong>product name</strong> because of quote ambiguity. So how to escape double quote &amp; resolve ambiguity.</p>
  
  <p>Thanks.</p>
