Error : getElementsByTagName() on a non-object in loop


Error : getElementsByTagName() on a non-object in loop

I hope this helps you . So based the loop off 5 and the number of items.
Not sure the syntax but with JS it would be
code :
for ($i=$j=0; $i<=5 && $i<$x.length ; $i++) {

wish help you to fix your issue DOMDocument::loadHTML — Load HTML from a string, not from a website address :) You need to use something like:
code :
    $dom->loadHTML(file_get_contents($wrss));

it helps some times In IE9, childNodes[] returns text nodes (comments or whitespace) as well as child tags. Text nodes do not support getElementsByTagName(). There's a good summary of the underlying DOM model here.
The easiest fix is just to check for the existence of the method before using it:
code :
function AreAllSiblingsChecked(chkBox)
{
     var parentDiv = GetParentByTagName("div", chkBox);
     var childCount = parentDiv.childNodes.length;
     for(var i=0;i<childCount;i++)
     {
         if (parentDiv.childNodes[i].getElementsByTagName) {
             var prevChkBox = parentDiv.childNodes[i].getElementsByTagName("input")[0];
             //if any of sibling nodes are not checked, return false
             if(prevChkBox.checked)
             {
                return true;
             }
         }
     }
     return false;
}

help you fix your problem That's because (with apologies) NodeList objects don't have a method called getElementsByTagName.
Let's break it down:
code :
document.getElementById("myDiv")
.getElementsByClassName("myTable")
.getElementsByTagName("td")[0]
var foo= document.getElementById("myDiv").getElementsByClassName("myTable")[0].getElementsByTagName("td")[0]
// Change here ------------------------------------------------------------^^^
var foo = document.querySelector("#myDiv .myTable td");
var foo = document.querySelectorAll("#myDiv .myTable td");

Does that help You have while($i<=9) then you ask for each element, 0-9. So when you don't have 10 elements, $x->item($i) returns nothing, and thus calling ->getElementsByTagName('title') gives an error since you're calling the method on nothing.
You want to restructure to this:
code :
<?php 
$q=$_GET["q"];
$xml = $q;
$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);
$channel=$xmlDoc->getElementsByTagName('channel')->item(0);
$channel_title = $channel->getElementsByTagName('title')->item(0)->childNodes->item(0)->nodeValue;
$channel_desc = $channel->getElementsByTagName('description')->item(0)->childNodes->item(0)->nodeValue;
echo("<b> $channel_title </b>" );
echo("<br>");
echo($channel_desc . "</p>");
$x=$xmlDoc->getElementsByTagName('item');

$counter = 0 ;
foreach($x as $item)
  {
      if(++$counter > 9) break;
      $item_title=$item->getElementsByTagName('title')->item(0)->childNodes->item(0)->nodeValue;
      $item_desc=$item->getElementsByTagName('description')->item(0)->childNodes->item(0)->nodeValue;
      echo ("<b> $item_title </b>"  );
      echo ("<br>");
      echo ($item_desc . "</p>"); 
  }
?>

I wish did fix the issue. Want to answer my own question...................I think those old javaScript library file were not compatible with the new versions of IE9. So, I just changed the referenced js libraries files to latest one from this page....developers.google.com/speed/libraries and everything is working fine now....
