visit - XTiSP/IV

A visit expression is used as the form:

visit `xpath` do exp done

It returns an element corresponding the current node in which every node satisfying xpath is replaced with the result of exp after the current node is moved to the node. You can use before-notation in xpath.

Consider the following XTiSP program:

visit `.//TITLE` do
 <NAME> [ { value() } ]
done

Suppose that the input XML is

<PLAY><TITLE>R and J</TITLE>
<SCENE><TITLE>Prologue</TITLE></SCENE></PLAY>

The XTiSP program above returns

<PLAY><NAME>R and J</NAME>
<SCENE><NAME>Prologue</NAME></SCENE></PLAY>
