, I use a single search for it because I think it represents the way the library will be used in practice. But of course, XPath is generally slower than walking through the tree manually, so it adds benchmarks for these libraries. So no matter how-I will discuss how to execute the situation with the sample written to my device here, it is the result-but always give it one on your device, or adjust the actual XML data and parse the code lens you need!
