How to use XQuery to search a collection of XML documents
Use the collection() function to load a collection of XML documents and search using FLWOR expressions and XPath filter conditions. For example, use collection('books')//book to find books with "XML" in the title, use where to filter product names with prices greater than 50, or use document-uri() to return matching document paths to achieve efficient cross-file query and data extraction.

How to implement a simple XML database in Python
Answer: Use Python's xml.etree.ElementTree module to build a lightweight XML database, suitable for storing configuration or small-scale data. 1. Design the XML structure, such as book information including title, author, year and other fields; 2. Use ET.parse() to load the XML file and parse it into a tree structure, and traverse the data through root.findall(); 3. Use ET.SubElement to create new elements when adding records and write them back to the file; 4. Search, update or delete data by finding matches and modifying node content, and call tree.write() after each operation to persist and save. This solution is suitable for low concurrency scenarios and large-scale applications.

Verification can be performed during parsing to ensure data consistency; 6. Although older, it is simple and universal, and is now mostly replaced by XSD.
