I am trying to create an XSD to validate a series of documents generated in XML format .

I have tried the following:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="proceso_cajero">
    <xs:complexType>
      <xs:sequence>
        <xs:element maxOccurs="unbounded" name="evento">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="ID_INSTANCIA" type="xs:string" />
              <xs:element name="ACTIVIDAD" type="xs:string" />          
            </xs:sequence>
              <xs:any minOccurs="1"/>

          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

What I need and am trying to do in that piece of code is to validate that the XML file has 2 elements inside the element "evento"in that order "ID_INSTANCIA"- "ACTIVIDAD"and then several elements but not required. If it is mandatory for at least one element to come after the sequence .

The target XML file can have this structure:

<?xml version="1.0" encoding="UTF-8" ?>
<proceso_cajero>
  <evento>
    <ID_INSTANCIA>XXXXX</ID_INSTANCIA>
    <ACTIVIDAD>XXXXXXXXX</ACTIVIDAD>

    <MONEDA>XXX</MONEDA>
    <MONTO>XXX</MONTO>

  </evento>
</proceso_cajero>

When trying to perform the validation, it shows me an error on the line where I declare the element <xs:any>:

"Unable to parse schema file, the content is not valid expected is (annotation,simplecontent,complexcontent, ... )"

I have site A on Wordpress and site B on PHP. How can I achieve that if a user tries to enter my site B without being logged in to my site A, he is redirected to the login page of my site A.

I have searched for information on how to redirect from a form to an external page, but I have not found what I need, because in my case if you wanted to access site B directly from the URL, you should automatically be redirected to site A.

I'm doing a small project in Symfony 2.8, and what I'm trying to do is perform a query doctrinethat adds the values ​​of a column of a table and sends the total to my página.html.twig.

Here is the code I have written in the controller class where I want to perform this operation:

class DefaultController extends Controller
{
    public function indexAction()
    {
        $em = $this->getDoctrine()->getManager();
        $query_ganancia = $em->createQuery('
            SELECT SUM(v.ingresos)
            FROM CarroBundle:Viaje v
        ');

        $var_ganancia = $query_ganancia->getResult();


        return $this->render('CarroBundle:Default:index.html.twig', array('ganancia'=> $var_ganancia));
    }
}  

And in the page I get the value as follows:

<h1>{{ ganancia }}</h1>  

But for some reason that I still don't see, it keeps returning this exception :

An exception has been thrown during the rendering of a template ("Notice: Array to string conversion") in CarroBundle:Default:index.html.twig at line 39.  

I have searched the Symfony 2.8 guide regarding Doctrineand tried to perform the operation in this other way without result:

$var_ganancia = $query_ganancia->setMaxResults(1)->getOneOrNullResult();  

I would like someone to guide me on this error. Thanks.
