Get Sub String

This is a pre-built Action located under the @Generic Element. The functionality of this Action in Avo Assure is to extract a specific part of the input text based on the given index or range. The extracted portion is stored in a dynamic variable.

Syntax

Input Value: <string>;<index OR range>

Argument	Description
<string > (Required)	Provide the full string from which you want to extract a part.
<index OR range > (Required)	Provide the position or range of characters you want to extract.

Note:

• The index value starts from the 0^th index till N^th index.

• Index: The extraction starts from the given index and continues until the end of the string.

• Range: Use the format StartIndex–EndIndex. The extraction starts from the StartIndex and stops just before the EndIndex. To include the last character, increase the EndIndex by 1 (total range+1).

Output Value: <Dynamic Varibale>;<Dynamic Variable>(Optional)

Argument	Description
<Dynamic Variable> (Required)	This dynamic variable stores a specific portion of a string.
<Dynamic Variable> (Optional)	This dynamic variable stores the status as True or False.

Example 1: Extracting a Substring from a String Using Index Value

In this example, we explain how to extract a part of a string starting from a specific index in Input Value.

• Action: Get Sub String

• Input Value: Software Engineer;4

  • The first argument (Software Engineer) specifies the main string,

  • The second argument (4) specifies the starting index from which the substring is extracted.

• Output Value: {Sub string}

  • The extracted substring (ware Engineer) is stored in this {Sub string} dynamic variable for further use.

  • If the second output variable is defined, it stores the action status with the following possible values:

    • True: If the substring is successfully extracted.

    • False: If the input value is empty or invalid.

• Logical Explanation: The Get Sub String action fetches the value from the Input Value column (Software Engineer;4) and extracts the substring starting from the specified index (4). For the given input, the resulting substring is (ware Engineer). The extracted substring is stored in the {Sub string} variable.

Example 2: Extracting a Substring from a String Using a Range Value

In this example, we explain how to extract a part of a string using a specific range in Input Value.

• Action: Get Sub String

• Input Value: Software Engineer;9–17

  • The first argument (Software Engineer) specifies the main string,

  • The second argument (9–17) defines the range of characters to extract.

• Output Value: {Sub string}

  • The extracted substring (Engineer) is stored in this {Sub string} dynamic variable for further use.

  • If the second output variable is defined, it stores the action status with the following possible values:

    • True: If the substring is successfully extracted.

    • False: If the extraction fails due to an invalid range or input.

• Logical Explanation: The Get Sub String action fetches the value from the Input Value column (Software Engineer;9-17) and extracts the substring based on the specified range (9–17). For the given input string, the resulting substring is (Engineer). The extracted substring is stored in the {Sub string} variable.

Knowledge Bites:

Here are some examples of different string scenarios:

String	Input Value	Result
Text Strings	index: Automation;4 OR range: Automation;3-10	index: mation OR range: omation
Numeric Strings	index: 12345678;4 OR range: 12345678;3-10	index: 5678 OR range: 45678
Special Character	index: [email protected];4 OR range: [email protected];3-10	index: domain.com OR range: @domain
Alphanumeric strings	index: ID2025;4 OR range: ID2025;3-6	index: 25 OR range: 025
