Answer 1

If you take a look at the function getFeedData() in class Mage_AdminNotification_Model_Feed you can see that your error line 173 is Magento calling new SimpleXMLElement with a parameter $data.

/**
 * Retrieve feed data as XML element
 *
 * @return SimpleXMLElement
 */
public function getFeedData()
{
    $curl = new Varien_Http_Adapter_Curl();
    $curl->setConfig(array(
        'timeout'   => 2
    ));
    $curl->write(Zend_Http_Client::GET, $this->getFeedUrl(), '1.0');
    $data = $curl->read();
    if ($data === false) {
        return false;
    }
    $data = preg_split('/^\r?$/m', $data, 2);
    $data = trim($data[1]);
    $curl->close();

    try {
        $xml  = new SimpleXMLElement($data);
    }
    catch (Exception $e) {
        return false;
    }

    return $xml;
}

Here $data is the return of a cURL call on Magento feed, so the problem is probably that the return from Magento is not correctly formated.
If this error persist you may think about your file encoding but the first explanation seems to be the most probable to me.

---

Basically your error mean that $data value is ts}if("function"==typeof __nr_require)return __nr_require;for(var o=0;o<n.length so that is why I telling you it is most probably a Magento side error, not yours.

Answer 2

It looks like something is breaking the adminhtml feed module.

The cause could be a third-party module that is retrieving invalid XML.

Check whether your site code contains any class which extends Mage_AdminNotification_Model_Feed.

Once you find it:

->Try to disable that module from app/etc/modules/

->Clean the system.log.

->See if the error is gone.

Once you've determined which module is creating the issue, contacting the module's developer and notifying them about the issue.
