Some of the following term definitions have been borrowed or
modified from similar definitions in other W3C or standards documents.
See the links within the definitions for more information.
- An API is an Application Programming
Interface, a set of functions or methods used to access some
- document element
There is only one document element in a
element node is a child of the
Document node. See
Documents in XML [XML 1.0].
- document order
- There is an ordering, document order, defined on all
the nodes in the document corresponding to the order in which the first
character of the XML representation of each node occurs in the XML
representation of the document after expansion of general entities. Thus,
the document element node
will be the first node. Element nodes occur before their children. Thus,
document order orders element nodes in order of the occurrence of their
start-tag in the XML (after expansion of entities). The attribute nodes
of an element occur after the element and before its children. The
relative order of attribute nodes is implementation-dependent.
- Each document contains one or more elements, the
boundaries of which are either delimited by start-tags and
end-tags, or, for empty elements by an empty-element tag.
Each element has a type, identified by name, and may have a
set of attributes. Each attribute has a name and a value.
Structures in XML [XML 1.0].
- logically-adjacent text nodes
Logically-adjacent text nodes are
CDATASection nodes that can be visited
sequentially in document
order or in reversed document order without entering,
exiting, or passing over
- An object is live if any change to the underlying
document structure is reflected in the object.
- A model is the actual data representation
for the information at hand. Examples are the structural
model and the style model representing the parse structure
and the style information associated with a document. The
model might be a tree, or a directed graph, or something
- namespace prefix
- A namespace prefix is a string that associates
an element or attribute name with a namespace URI in
XML. See namespace
prefix in Namespaces in XML [XML Namespaces].
- namespace URI
A namespace URI is a URI that identifies an XML
namespace. This is called the namespace name in
Namespaces in XML [XML Namespaces]. See also sections 1.3.2 "DOM
URIs" and 1.3.3 "XML
Namespaces" regarding URIs and namespace URIs
handling and comparison in the DOM APIs.
- read only node
- A read only node is a node that is immutable. This
means its list of children, its content, and its attributes, when it
is an element, cannot be changed in any way. However, a read only node
can possibly be moved, when it is not itself contained in a read only
