The XML declaration indicates that the document is written in XML and specifies which version of XML. The XML declaration, if included, must be on the first line of the document.
The XML declaration can also specify the language encoding for the document (optional) and if the application refers to external entities (optional). In our example, we specify that the document uses UTF-8 encoding (although we don't really need to as UTF-8 is the default), and we specify that the document refers to external entities by using
standalone="no"
. This is not a standalone document as it relies on an external resource (i.e. the DTD).An XML element is everything from (including) the element's start tag to (including) the element'send tag. <price>29.99</price> An element can contain: text.
An XML element is everything from (including) the element’s start tag to (including) the element’send tag.
