This blog provides a quick guide to find and use XPath in Selenium. XPath uses path expressions to navigate through elements, attributes, and select nodes or node-sets. The basic syntax of an XPath expression is: Xpath=//tagname. Make sure that you have installed a Selenium library. If you haven't, you can have a look at Selenium documentation for how-to guides.

The consumer group is a cornerstone of Apache Kafka, enabling scalable and fault-tolerant data consumption by allowing multiple consumer instances to share the workload of reading from topic partitions. The consumer rebalance protocol is the mechanism that coordinates which partitions are assigned to which consumers within a group.
