Usecase/Example

Scenario: Fetching Values from XML Blocks in API Testing

When you are testing a financial services API that returns a user's transaction history in XML format. It's important to verify that not only the correct number of transaction blocks is returned, but also that the values within those blocks are accurate.

Consider that you send a request to the API to retrieve the latest 4 transactions for a specific user and want to extract specific block values from the XML response. In this scenario user wants to fetch the value of 2 child blocks from parents block by providing parents block name.

Retrieves the value of a specific tag from a selected block within the XML structure The Get Block Value action takes the value from the Input Value column (e.g., Name;2;User) and extracts the value of the specified XML tag (Name) from the block (User) at the given index (2). The result of the extraction is stored in the {BlockValue} variable, while the execution status is stored in the {Status} variable, with the following possible values:

• True – if the tag value is successfully retrieved.

• False – if the extraction fails or an error occurs.
