Dúvida a respeito de validação de XML com XSD

Mobile
#1

Bom dia a todos, gostaria de saber se é necessário algo em minha aplicação para realizar essa validação, ou se preciso apenas indicar meu XSD no XML, utilizo o KXML.

Meus arquivos para teste:

XML (teste.xml):

<?xml version="1.0" encoding="UTF-8"?>
<order xmlns="urn:nonstandard:test"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="urn:nonstandard:test 
     file:./test.xsd">
    <user>
        <fullname>Bob Jones</fullname>
        <deliveryAddress>
            123 This road,
            That town,
            Bobsville
        </deliveryAddress>
    </user>
    <products>
        <product id="12345" quantity="1" />
        <product id="3232" quantity="3" />
    </products>
</order>

XSD(teste.xsd):

 <?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            elementFormDefault="qualified"
            xmlns="urn:nonstandard:test" 
            targetNamespace="urn:nonstandard:test">


    <xsd:element name="order" type="Order" />
    <xsd:complexType name="Order">
        <xsd:all>
            <xsd:element name="user" type="User" minOccurs="1" maxOccurs="1" />
            <xsd:element name="products" type="Products" minOccurs="1" maxOccurs="1" />
        </xsd:all>
    </xsd:complexType>


    <xsd:complexType name="User">
        <xsd:all>
        
            <xsd:element name="deliveryAddress" type="xsd:string" />
        
            <xsd:element name="fullname">
                <xsd:simpleType>
                    <xsd:restriction base="xsd:string">
                        <xsd:maxLength value="30" />
                    </xsd:restriction>
                </xsd:simpleType>
            </xsd:element>
            
        </xsd:all>
    </xsd:complexType>


    <xsd:complexType name="Products">


        <xsd:sequence>
            <xsd:element name="product" type="Product" minOccurs="1" maxOccurs="unbounded" />
        </xsd:sequence>
    </xsd:complexType>


    <xsd:complexType name="Product">
        <xsd:attribute name="id" type="xsd:long" use="required" />
        <xsd:attribute name="quantity" type="xsd:positiveInteger" use="required" />
    </xsd:complexType>


</xsd:schema>
