Parameters

Name

Description

string

xs:string

The input string (that is, the "haystack").

substr

xs:string

The substring (that is, the "needle").

collation

xs:string

Specifies the collation to use for string comparison. This input may originate from the output of the default-collation function or it may be a collation such as http://www.w3.org/2005/xpath-functions/collation/html-ascii-case-insensitive.

 

Example

The following mapping returns the value true, because the input string "MapForce" begins with the substring "Map", assuming that the default Unicode collation is used.
