public class ResultDocumentFunction
extends CompileTimeFunction

This class implements the extension function saxon:result-document(), which offers similar functionality in XQuery to the xsl:result-document instruction in XSLT 2.0. The three arguments are

1. The URI of the result document (href) - a string
2. The content of the result document - a content sequence processed in the same way as the sequence passed to xsl:result-document (or to the document {} constructor in XQuery)
3. An xsl:output element which contains serialization properties in the same way as saxon:serialize()

The class implements a compile-time function, which is translated into a ResultDocument instruction for evaluation at run-time.

Method Detail

simplify

public Expression simplify(ExpressionVisitor visitor)
                    throws XPathException

Simplify the function call. Default method is to simplify each of the supplied arguments and evaluate the function if all are now known.

Overrides:

simplify in class FunctionCall

Parameters:

visitor - an expression visitor

Returns:

the simplified expression

Throws:

XPathException - if an error is discovered during expression rewriting
