<?php/*When I try to get a some attribute from not validated HTML or XML document, PHP dies with no errors in logs or output:*/        function is_attribute_value($obj,$type,$value)        {            $_ret=false;            if($obj)            {                if($val=$obj->getAttribute($type))                {                    if($val==$value)                    {                        $_ret=true;                    }                }            }            return $_ret;        }//And this check helped to me:        function is_attribute_value($obj,$type,$value)        {            $_ret=false;            if($obj->attributes)            {                if($val=$obj->getAttribute($type))                {                    if($val==$value)                    {                        $_ret=true;                    }                }            }            return $_ret;        }?>
