XQUERY Certification
About XQUERY
XQuery (XML Query Language) is a query and programming language that is used to extract data from XML documents. It is designed to work with large and complex XML data sets and allows developers to query, transform, and manipulate the data in a flexible and efficient way.
XQuery is based on XPath, a query language for selecting elements in an XML document. XQuery extends XPath by adding features such as the ability to create new elements and attributes, to update and delete elements, and to perform advanced calculations and string operations.
XQuery is also designed to be used in conjunction with other XML-based technologies such as XPath, XSLT (eXtensible Stylesheet Language Transformations) and XPointer.
It can be used to extract data from XML documents, to combine data from different sources, and to transform data into other formats such as HTML, JSON, or CSV. XQuery is also used to query databases, retrieve and modify data from web services, and to perform other data-related tasks.
In summary, XQuery (XML Query Language) is a query and programming language that is used to extract data from XML documents. It allows to query, transform, and manipulate the data in a flexible and efficient way. It's based on XPath and extend it by adding features such as the ability to create new elements and attributes, to update and delete elements, and to perform advanced calculations and string operations.
