Iteration over Node Sets

Description For each node in path, evaluate the template. The loop variable, var, is optional, and if used becomes both an XPath variable and the Java loop variable.

Simple Form

#for var "path"#
template
#end#

XML Form

<for var="var" path="path">
template
</for>

Translation to Java

NodeList x = context.evalNodeSet("path");
for (int j; j<x.getLength(); ++j) {
    Node var = (Node) x.item(j);
    context.push(var, j+1, x.getLength());
    template-translated-to-java
    context.pop();
}

Example Template

Dict.template


public class Dict {

	String[] words = {
	#for "//word"#
		"#"."#",
	#end#
	};
}

Example Spec

words.xml


<?xml version="1.0"?>
<words>
  <word>hill</word>
  <word>fetch</word>
  <word>pail</word>
  <word>water</word>
  <word>up</word>
  <word>down</word>
  <word>crown</word>
</words>

Generated Output

Dict.java


public class Dict {

	String[] words = {
		"hill",
		"fetch",
		"pail",
		"water",
		"up",
		"down",
		"crown",
	};
}
