Remarks
An XML document literal is identified by the XML declaration at the start of the literal. Although each XML document literal must have exactly one root XML element, it can have any number of XML processing instructions and XML comments.
An XML document literal cannot appear in an XML element.
Note
An XML literal can span multiple lines without using line continuation characters. This enables you to copy content from an XML document and paste it directly into a Visual Basic program.
The Visual Basic compiler converts the XML document literal into calls to the #ctor and #ctor constructors.
Example
The following example creates an XML document that has an XML declaration, a processing instruction, a comment, and an element that contains another element.
Dim libraryRequest As XDocument =
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<?xml-stylesheet type="text/xsl" href="show_book.xsl"?>
<!-- Tests that the application works. -->
<books>
<book/>
</books>
Console.WriteLine(libraryRequest)
