How to use LINQ to XML to query XML data?

Short answer: XDocument doc = XDocument.Parse(xml); var names = doc.Descendants("Employee") .Select(x => x.Element("Name")?.Value);

Example code

XDocument doc = XDocument.Parse(xml);
var names = doc.Descendants("Employee")
.Select(x => x.Element("Name")?.Value);

Real-world example (ShopNest)

ShopNest uses LINQ to query orders: filter by date, project to a summary DTO, and order by total—readable C# that becomes SQL under EF Core.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
