The functions in the "constructors" sub-library of the XPath 2.0 library construct specific data types from the input text. The following table lists the available constructor functions.

xs:nonPositiveInteger

xs:ID

xs:duration

xs:normalizedString

xs:IDREF

xs:float

xs:positiveInteger

xs:NCName

xs:gDay

xs:short

xs:NMTOKEN

xs:gMonth

xs:string

xs:Name

xs:gMonthDay

xs:time

xs:QName

xs:gYear

xs:token

xs:anyURI

xs:gYearMonth

xs:unsignedByte

xs:base64Binary

xs:hexBinary

xs:unsignedInt

xs:boolean

xs:int

xs:unsignedLong

xs:byte

xs:integer

xs:unsignedShort

xs:date

xs:language

xs:untypedAtomic

xs:dateTime

xs:long

xs:yearMonthDuration

xs:dayTimeDuration

xs:negativeInteger


xs:decimal

xs:nonNegativeInteger


 

 

Languages

XQuery, XSLT 2.0.

 

Example

Typically, the lexical format of the input text must be the one expected of the data type to be constructed. Otherwise, the transformation will not be successful. For example, to construct an xs:dateTime value using the xs:dateTime constructor function, the input text must have the lexical format of the xs:dateTime data type, which is YYYY-MM-DDTHH:mm:ss.

In the mapping illustrated above, a string constant ("2020-04-28T00:00:00") has been used to provide the input argument of the function. The input could also have been obtained from an item in the source document.  The xs:dateTime function returns the value 2020-04-28T00:00:00 of type xs:dateTime.

 

To view the expected data type of a mapping item (including the data type of function arguments), move the mouse cursor over the respective input or output connector.
