I am trying to validate the following XML using a schema.

<?xml version="1.0" encoding="ISO-8859-1"?> <Noticias xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="UXMLS-5.xsd"> <Noticia dia="12" mes="3" año="2004" seccion="Nacional"> <medio tipo="radio">Onda Cero</medio> <periodista>Fermín Bocos</periodista> <titular>Atentado bestial en Madrid</titular> <resumen>Resumen de la noticia Atentado bestial en Madrid</resumen> </Noticia> </Noticias>

and I am stuck when validating the below line from the above: 

<medio tipo="radio">Onda Cero</medio>

I am capable of validating "Noticia", which has attributes, as it isn't a final element with a type associated, I can't when it is the child element with content associated to it though.

I tried many approaches, with not luck so far, also I wasn't able to find a solution online. Any ideas? Am I missing something or is it just not possible doing it?

UPDATE: This is the XSD so far, keep in mind that the "medio" bit is wrong.

<?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> <xs:element name="Noticias"> <xs:complexType> <xs:sequence> <xs:element name="Noticia" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs:element name="medio" type="xs:string"> <xs:attribute name="tipo" type="xs:string"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="radio"/> <xs:enumeration value="prensa"/> <xs:enumeration value="television"/> </xs:restriction> </xs:simpleType> </xs:attribute> </xs:element> <xs:element name="periodista" type="xs:string"/> <xs:element name="titular" type="xs:string"/> <xs:element name="resumen"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:pattern value="[a-zA-Z0-9]{60}"/> </xs:restriction> </xs:simpleType> </xs:element> </xs:sequence> <xs:attribute name="dia" type="dia"/> <xs:attribute name="mes" type="mes"/> <xs:attribute name="año" type="xs:integer"/> <xs:attribute name="seccion" type="xs:string"/> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:simpleType name="dia"> <xs:restriction base="xs:integer"> <xs:minInclusive value="1"/> <xs:maxInclusive value="12"/> </xs:restriction> </xs:simpleType> <xs:simpleType name="mes"> <xs:restriction base="xs:integer"> <xs:minInclusive value="1"/> <xs:maxInclusive value="31"/> </xs:restriction> </xs:simpleType> </xs:schema>

  • How does your XSD look so far? Commented Jan 28, 2018 at 12:11

  • The thing that you're trying to define is called a "complex type with simple content": knowing that should help you find the right information. Commented Jan 28, 2018 at 17:18

There are two problems with your validation markup:

  1. You've been missing xs:complexType and xs:simpleContent elements around your xs:attribute. And an <xs:extension base="xs:string"> for specifying the value type of the content of the element like explained here at W3Schools.

So the medio code should look like this:

<xs:element name="medio"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="tipo"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="radio"/> <xs:enumeration value="prensa"/> <xs:enumeration value="television"/> </xs:restriction> </xs:simpleType> </xs:attribute> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element>

  1. Another problem(not part of your question): Your xs:pattern should be from 1 to 60 chars instead of exactly 60 chars and include spaces:

    <xs:pattern value="[\sa-zA-Z0-9]{1,60}"/>

Now your XSD should work as exprected.
