queries,??™??™ will explain it.
Chapters 3 and 4 go deeper into LINQ and the standard query operators, so don??™t worry about understanding

The following sections discuss LINQ to XML, which uses LINQ to query XML data, and LINQ to SQL,
which uses LINQ to query relational data.
LINQ to XML Overview
LINQ to XML, or XLINQ, is the XML integration of the Language Integrated Query. LINQ to XML
utilizes the standard query operators to provide the ability to query XML data. Also at your disposal are

tree nodes such as descendants and siblings seamlessly and efficiently.
