Class FuncDocument

  • All Implemented Interfaces:
    java.io.Serializable, javax.xml.transform.SourceLocator, ExpressionNode, ExpressionOwner, XPathVisitable
    public class FuncDocument
extends Function2Args
    Execute the Doc() function. When the document function has exactly one argument and the argument is a node-set, then the result is the union, for each node in the argument node-set, of the result of calling the document function with the first argument being the string-value of the node, and the second argument being a node-set with the node as its only member. When the document function has two arguments and the first argument is a node-set, then the result is the union, for each node in the argument node-set, of the result of calling the document function with the first argument being the string-value of the node, and with the second argument being the second argument passed to the document function.
