Do you have control over the XML? If so, ensure the data is enclosed in .. ]]> blocks.

And you also need to clear the invalid characters:

/**
 * Removes invalid XML
 *
 * @access public
 * @param string $value
 * @return string
 */
function stripInvalidXml($value)
{
    $ret = "";
    $current;
    if (empty($value)) 
    {
        return $ret;
    }

    $length = strlen($value);
    for ($i=0; $i < $length; $i++)
    {
        $current = ord($value{$i});
        if (($current == 0x9) ||
            ($current == 0xA) ||
            ($current == 0xD) ||
            (($current >= 0x20) && ($current <= 0xD7FF)) ||
            (($current >= 0xE000) && ($current <= 0xFFFD)) ||
            (($current >= 0x10000) && ($current <= 0x10FFFF)))
        {
            $ret .= chr($current);
        }
        else
        {
            $ret .= " ";
        }
    }
    return $ret;
}
