The data type supports several methods that let you query and modify individual elements, attributes, and their values directly within the XML instance, rather than having to work with that instance as a whole.In addition, the xml data type ensures that each XML instance is, at the very least, well formed according to ISO standards.Its universal acceptance and standardized methodology make it a simple yet effective way to move data between applications that serve different functions and are based on different technologies.You’ll often find that SQL Server documentation refers to the XML stored in an xml object (column, variable, or parameter) as an XML instance.In addition, an element’s opening tag can include attributes, such as id=”1234″, which is a combination of an attribute name (id) and it’s value (1234).You’ll also notice that the XML begins with a special type of tag called a declaration.For example, suppose you have a database that stores product information.For each product, you maintain an XML document that provides details about that product.
It uses tags to describe the nature of the data and how the data should be formatted.
To be considered a document, an XML instance must have only one root element, with no text specified at the top level.
Consequently, the following XML instance is considered a document: Both examples are considered XML instances, but only the first is a document. In some cases, you should use large object storage such as varchar(max) or nvarchar(max).
Unlike HTML, however, XML lets you define your own tags, thus its extensible nature, which is why XML is often referred to as a self-describing language.
Because it has been so universally adopted, you can use it to share a wide range of data across heterogeneous systems, as long as the XML conforms to ISO standards.
