Question

I call some cloud that allows to execute groovy scripts.
I return data as xml from this scripts.
I use code like this:

def writer;
def xml;
writer = new StringWriter();
xml = new MarkupBuilder(writer);

xml.Response() {
   node('arrtibute1': value4arrtibute1);
}

But I need to use more sophisticated way to calculating values. I want to put a lot of different nodes in this.

def writer;
def xml;
writer = new StringWriter();
xml = new MarkupBuilder(writer);

xml.Response() {
   Function1();
   Function2();
}

…
and implementations of this functions.

public void Function1(){
   node1('arrtibute1': value4arrtibute1);
}
public void Function2(){
   someOtherNode1('arrtibute1': otherValue4arrtibute1, ...);
}

Latest code doesn’t work. The reason why it doesn’t work is functions don’t know that they run in context of response and looking for methods node1 and someOtherNode1.

When I try to pass xml in functions and try to create new response there I have deformed structure of xml document (document in document).

My question: how to let code in function to “know” that they are run in context of response?

You need to pass the builder into the functions you are calling like so:

import groovy.xml.MarkupBuilder

value4arrtibute1 = 'val1'
otherValue4arrtibute1 = 'val2'

public void function1( MarkupBuilder builder ){
   builder.node1('arrtibute1': value4arrtibute1 )
}

public void function2( MarkupBuilder builder ){
   builder.someOtherNode1('arrtibute1': otherValue4arrtibute1 )
}

String output = new StringWriter().with { writer ->
  new MarkupBuilder(writer).with { xml ->
    xml.Response() {
      function1( xml )
      function2( xml )
    }
  }
  writer
}

println output
