![]() The prefix is specified in the construction of element. ![]() You can assign a prefix to the namespace. The construction of the child element undoes the declaration of the default namespace declared in the parent element. The following example uses a namespace declaration attribute in the construction of element to declare a default namespace. Using a Namespace Declaration Attribute to Add Namespaces You can bind the prefix to the namespace in the following ways:īy using a namespace declaration attribute. When constructing XML by using the direct constructors, the constructed element and attribute names can be qualified by using a namespace prefix. Rewrite your XQuery so it returns well-formed XML. The above query returns the following error: XML well-formedness check: Attribute cannot appear outside of element declaration. The value of element is computed by specifying a path expression inside curly braces (" ![]() For example, the following query constructs a element with one child element (). In the resulting XML, the expression is replaced by its value. You can use curly braces to specify query expressions. This is product model catalog description.Īlthough constructing elements from constant expressions, as shown in this example, is useful, the true power of this XQuery language feature is the ability to construct XML that dynamically extracts data from a database. Set is product model catalog description. Each of these nodes has one text node child and have the values Red, 25, 2 years parts and labor, respectively. The element has three element node children,, , and. The element has one text node child whose value is "Some description". The constructed element has three child elements The following example uses the direct element constructor expression and creates a element. In using XML notations, you can construct elements. The following examples illustrate XML construction by the direct constructors. When you use direct constructors, you specify XML-like syntax when you construct the XML. There is no difference between the direct and computed constructors.
