XML Query
XML Query refers to the process of retrieving, filtering, and manipulating data from XML documents using query languages and techniques. It enables developers to extract specific information from structured XML data, similar to how SQL queries work with relational databases. Common approaches include using XPath for node selection and XQuery for more complex querying and transformation operations.
Developers should learn XML Query when working with XML-based data formats, such as in web services (SOAP), configuration files, or document storage systems, to efficiently access and process structured information. It is essential for applications that need to parse, validate, or transform XML data, such as in data integration, content management, or API development, where precise data extraction is required.
