title: cross-browser 'getElementsByTagName' with namespace from responseXML
body: <p>Am trying to read an XML response using <code>getElementsByTagName</code>:</p>
  
  <pre><code>var rows = items.responseXML.getElementsByTagName("z:row");
  
  for (var i=0; i&lt;rows.length; i++)
  {
  //do something
  }
  </code></pre>
  
  <p>Above code works fine in Firefox and IE but in chrome it throws null.. i mean it does not get any data.. when i <code>alert</code> the <code>rows.length</code> it gives me <code>0</code> always in chrome.</p>
  
  <p>Then i searched in google and understood the issue is with <code>xsd:element</code>, then i changed <code>"z:row"</code> to only <code>"row"</code>. Then it worked in Chrome but Firefox and IE returned <code>0</code> for <code>rows.length</code>.</p>
  
  <p>Is there any method which across all browsers?</p>
