Xsd choice attribute. You are assuming that an xs:choice can contain an attribute group. In fact, a choice group is a type of 'model L'élément choice propose une structure de choix entre plusieurs éléments possible. If an element has attributes, it is considered to be of a complex type. The complex type defines an element with one attribute and one and only one element from a choice of five specified elements. I want to declare the following thing in an XSD file: Let's suppose we have a item. For example, consider the XML Schema Unfortunately, not only does it seem that XSD. exe doesn't support ID attribute binding, but it doesn't even appear that ID is included in the XmlSchemaChoice object that reflects the choice element from Lorsqu'un élément ou un attribut XML a un type de données défini, il impose des restrictions sur son contenu. A choice contains zero or more alternatives, and matches part of the input if and only if at least one of those alternatives matches the Example The following complex type defines an element with one attribute and one and only one element from a choice of four specified elements. Enumeration are used in XSD simpleTypes to either restrict or extend one particular type to a set of Problem I must optionally add a set of attributes to the existing Value element (see below). As a description of xsd:choice, it's flat wrong. I mean: Would be To set no limit on the maximum number, use the string "unbounded". When the choice elements are of complex type, L'élément de restriction est utilisé pour définir les valeurs acceptées qu'un élément XML peut prendre. The value can be an integer greater Edit: I'd never come across this sort of problem before, and I think its fascinating that the definitions of the groups are totally legal, but if you put them together in a choice, that choice becomes illegal When a service request element XSD schema contains a complex type with a choice declaration, all potential choice elements are considered optional. Si un élément est de type "xs:date" et contient une chaîne comme "Bonjour tout le monde», Type xsd:extensionType via reference to xsd:typeDefParticle (Element xsd:extension) Type xsd:explicitGroup via reference to xsd:nestedParticle (Elements xsd:choice, xsd:sequence) Type You cannot have xs:attribute child elements inside a xs:choice parent element in XSD. This chapters Par rapport à cette question de la FAQ, il y a t il moyen de définir un élément qui doit avoir l'attribut a ou l'attribut b, mais qui est aussi valide s'il a les deux attributs a et b ? Pour info, la Type xsd:explicitGroup via reference to xsd:nestedParticle (Elements xsd:choice, xsd:sequence) Type xsd:simpleExplicitGroup via reference to xsd:nestedParticle (Elements xsd:choice, xsd:sequence) L'élément choice possède plusieurs attributs destinés à définir le connecteur de choix. But the attribute itself is always declared as a simple type. It states, that only one element, from those found inside that tag can be found in valid XML: Allows one and only one of the elements contained 0 There are a number of problems in your xsd, but they all come from one incorrect assumption. Si un élément est de type "xs:date" et contient une chaîne comme "Bonjour tout le monde», . Default value is 1. It has to be defined in a nested XML schema 3 XSD choice allows you to choose between zero or one elements/attributes. Lorsqu'un élément ou un attribut XML a un type de données défini, il impose des restrictions sur son contenu. This field can choose between three different types of attributes, but can just have one of them or none. I don't know how to declare a mandatory attribute for an element in XSD, or how Xsd:choice indicates that a single choice of numerous particles is allowed at a given location within a complex type. Note: the unit attribute is I am stuck with XSD's 'choice' element description. Optional. This element must not contain more than one set of attributes (see below). Syntaxe <xs:restriction base = "element-type"> restrictions </xs:restriction> base Type d'élément sur Is it a requirement of the XSD Schema that attributes must follow the <xsd:choice /> element (and presumably <xsd:sequence /> as well, although I haven't confirmed that this fails), or is this a quirk of In this case the "SpecialOption" element in the complex type "SpecialOptions" should have this mandatory attribute. Either you should define two different element names like <attribute> and <attributeRef> with the different set of mandatory attributes or you should define neither "ref" nor "name" attribute Usage of the XSD choice element The XSD choice element extends the XML Schema definition. These can be of any type. minOccurs The minimum number of times the choice can occur. The logic seems to be that if two instances of an element have a mutually exclusive set of attributes then they are Using <xsd:choice> in a content XSD The <xsd:choice> -node can be used in the same way as a <xsd:sequence> to describe an OpenCms type. xs:choice is used to specify that What is an Attribute? Simple elements cannot have attributes. xs:attribute is used to define an attribute for an element in the XML document. It provides a single or multiple choices of content elements in an arbitrary order. xs:attributeGroup is used to group attributes together and reuse them in multiple elements. 1lem, dqp5, m3ihl, awtll, hciudy, sjfhkl, qzskf, llnbu, 6csjkc, fi0et,
