StringSearch

StringSearch

Introduced

5.0

Description

Exposes straightforward string search functionality, based on the InStr function that is built into VBScript.

JScript, Python and other languages provide regular expression support for very powerful string searching capabilities. However this command is provided as a straightfoward solution for the common task of trying to discover whether one string occurs within another.

Unlike VBScript's InStr, this command considers the first character of a string to be index 0. It also has a more conventional ordering of arguments.

Scripting Syntax

StringSearch( SearchTarget, SearchStr, [CaseSensitive], [StartPos] )

Parameters

Parameter	Type	Description
SearchTarget	String	String to search, can contain newline and other characters
SearchStr	String	String that we are looking for inside SearchTarget
CaseSensitive	Boolean	Whether to perform a case-sensitive search or not Default Value: true
StartPos	Long	Position to start the search. 0 is the first character Default Value: 0

Return Value

(Long) Position in SearchTarget of the first occurance of SearchStr, or -1 if SearchStr was not found. Position is relative to the beginning of the string, even if the StartPos argument was specified.

Examples
