XML-Import and constant number of lines

Hello community,

I can't figure out a  solution for my problem.

I import some XML containing addresses with XML-rule (JS):

  function addressStyling(){

        this.name = "addressStyling";

        this.xpath = "//address";

        this.apply = function(myElement, myRuleProcessor){

            with(myElement){

                var myAttribute = myElement.xmlContent;

                myElement.xmlContent.applyCharacterStyle(app.activeDocument.characterStyles.item("bold"), true);

                insertTextAsContent('\r', XMLElementPosition.ELEMENT_END);

            }

            return false;

        }

    }

The XML looks like this and unfortunately it is not structured well.

<addresses>

     <address>

     street1&#x2029;street2&#x2029;zipcode&#x2029;place

     </address>

     <address>

     street1&#x2029;zipcode&#x2029;place

     </address>

<addresses>

My problem is, that the layout is planned for exactly 4 rows (or lines) for this address.

Is there a InDesign-way of solving this problem or is it better to use some XSL and separate the string (e.g. by &#x2029;) into 4 separate children?

Thank you for your help!
