In a Selector, what does the 'idx' attribute signify?

The 'idx' attribute in a Selector signifies the position of the element among its siblings. This is particularly useful when dealing with elements that share the same parent or are part of a similar hierarchy within the Document Object Model (DOM). Each sibling element can be distinguished based on its order; for example, if there are several buttons within the same parent container, the 'idx' attribute allows the automation tool to select a specific button by referring to its sequence number.

This indexing mechanism simplifies element targeting when there are multiple elements of the same type, ensuring that the right element is interacted with during automation processes. The ability to accurately reference an element based on its sibling position helps in efficiently navigating complex structures and ensures reliable performance of automated tasks.
