fn:starts-with

Whether one string starts with another

Description

The fn:starts-with function returns an xs:boolean value indicating whether one string ($arg1) starts with the characters of another string ($arg2). Leading and trailing whitespace is significant, so you may want to use the fn:normalize-space function to trim the strings before using this function.
