context node

From XML Path Language (XPath) (1999-11-16)

the context node

context position

From XML Path Language (XPath) (1999-11-16)

the context position

context size

From XML Path Language (XPath) (1999-11-16)

the context size

descendants

From XML Path Language (XPath) (1999-11-16)

The descendants of a node are the children of the node and the descendants of the children of the node.

document order

From XML Path Language (XPath) (1999-11-16)

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 root 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 and namespace nodes of an element occur before the children of the element. The namespace nodes are defined to occur before the attribute nodes. The relative order of namespace nodes is implementation-dependent. The relative order of attribute nodes is implementation-dependent.

expanded-name

From XML Path Language (XPath) (1999-11-16)

Some types of node also have an expanded-name, which is a pair consisting of a local part and a namespace URI. The local part is a string. The namespace URI is either null or a string. The namespace URI specified in the XML document can be a URI reference as defined in ; this means it can have a fragment identifier and can be relative. A relative URI should be resolved into an absolute URI during namespace processing: the namespace URIs of expanded-names of nodes in the data model should be absolute.

parent

From XML Path Language (XPath) (1999-11-16)

Every node other than the root node has exactly one parent, which is either an element node or the root node.

principal node type

From XML Path Language (XPath) (1999-11-16)

Every axis has a principal node type. If an axis can contain elements, then the principal node type is element; otherwise, it is the type of the nodes that the axis can contain.

proximity position

From XML Path Language (XPath) (1999-11-16)

The proximity position of a member of a node-set with respect to an axis is defined to be the position of the node in the node-set ordered in document order if the axis is a forward axis and ordered in reverse document order if the axis is a reverse axis. The first position is 1.

reverse document order

From XML Path Language (XPath) (1999-11-16)

Reverse document order is the reverse of document order.

string-value

From XML Path Language (XPath) (1999-11-16)

For every type of node, there is a way of determining a string-value for a node of that type. For some types of node, the string-value is part of the node; for other types of node, the string-value is computed from the string-value of descendant nodes.
