public abstract class XdmItem
The class XdmItem represents an item in a sequence, as defined
by the XDM data model. An item is either an atomic value or a node.
An item is a member of a sequence, but it can also be considered as
a sequence (of length one) in its own right. XdmItem is a subtype
of XdmValue because every Item in the XDM data model is also a
value.
It cannot be assumed that every sequence of length one will be
represented by an XdmItem. It is quite possible for an XdmValue
that is not an XdmItem to hold a singleton sequence.
| Method Summary | |
|---|---|
bool |
IsAtomic()Determine whether the item is an atomic value |
String |
GetStringValue()Get the string value of the item. For a node, this gets the string value of the node. For an atomic value, it has the same effect as casting the value to a string. In all cases the result is the same as applying the XPath string() function. For atomc values, the result is the same as the result of calling toString. This is not the case for nodes, where toString returns an XML serialization of the node. |
