Decorators

TypeSpec.Xml

@attribute

Specify that the target property should be encoded as an XML attribute instead of node.

@TypeSpec.Xml.attribute

Target

ModelProperty

Parameters

None

Examples

Default

model Blob {
  id: string;
}

<Blob>
  <id>abcdef</id>
</Blob>

With @attribute

model Blob {
  @attribute id: string;
}

<Blob id="abcdef">
</Blob>

@name

Provide the name of the XML element or attribute. This means the same thing as @encodedName("application/xml", value)

@TypeSpec.Xml.name(name: valueof string)

Target

unknown

Parameters

Name	Type	Description
name	valueof string	The name of the XML element or attribute

Examples

@name("XmlBook")
model Book {
  @name("XmlId") id: string;
  @encodedName("application/xml", "XmlName") name: string;
  content: string;
}

<XmlBook>
  <XmlId>string</XmlId>
  <XmlName>string</XmlName>
  <content>string</content>
</XmlBook>

@ns

Specify the XML namespace for this element. It can be used in 2 different ways:

1. @ns("http://www.example.com/namespace", "ns1") - specify both namespace and prefix
2. @Xml.ns(Namespaces.ns1) - pass a member of an enum decorated with @nsDeclaration

@TypeSpec.Xml.ns(ns: string | EnumMember, prefix?: valueof string)

Target

unknown

Parameters

Name	Type	Description
ns	string | EnumMember	The namespace URI or a member of an enum decorated with @nsDeclaration.
prefix	valueof string	The namespace prefix. Required if the namespace parameter was passed as a string.

Examples

With strings

@ns("https://example.com/ns1", "ns1")
model Foo {
  @ns("https://example.com/ns1", "ns1")
  bar: string;

  @ns("https://example.com/ns2", "ns2")
  bar: string;
}

With enum

@Xml.nsDeclarations
enum Namespaces {
  ns1: "https://example.com/ns1",
  ns2: "https://example.com/ns2",
}

@Xml.ns(Namespaces.ns1)
model Foo {
  @Xml.ns(Namespaces.ns1)
  bar: string;

  @Xml.ns(Namespaces.ns2)
  bar: string;
}

@nsDeclarations

Mark an enum as declaring XML namespaces. See @ns

@TypeSpec.Xml.nsDeclarations

Target

Enum

Parameters

None

@unwrapped

Specify that the target property shouldn’t create a wrapper node. This can be used to flatten list nodes into the model node or to include raw text in the model node. It cannot be used with @attribute.

@TypeSpec.Xml.unwrapped

Target

ModelProperty

Parameters

None

Examples

String property default

model BlobName {
  content: string;
}

<BlobName>
  <content>

model BlobName {
  @unwrapped content: string;
