XQuery is a powerful language used for querying and transforming XML data. If you’re interested in learning the basics, here are some key concepts to get you started:

1. Basic Syntax

• XQuery is case-sensitive.
• Use let, for, where, and return to construct queries.

2. Selecting Nodes

• Use the // operator to select nodes from anywhere in the XML document.
• Use . to refer to the current node.

3. Functions

• Built-in functions like count(), string(), and substring() are commonly used.

4. Filtering

• Use where to filter results based on conditions.

5. Combining Data

• Use union to combine results from different queries.

Example Query

Here’s a simple example to select all book titles from an XML document:

for $book in //book
return $book/title
