Re: ibatis to return xml instead of arraylist (of hashmap).

[Larry Meadors]

Vic,

You could write a row handler to take the returned maps and a string
builder to create xml.

One class would handle all of your requirements.

Something like this is close - testing is an exercise left to the reader. ;-)

public class MapToXmlRowHandler
       implements RowHandler
{
   private String wrapper;
   private String item;
   private StringBuilder builder;


   public MapToXmlRowHandler(String wrapper, String item) {
       this.wrapper = wrapper;
       this.item = item;
       builder = new StringBuilder();
   }

   public void handleRow(Object object) {
       Map<String, Object> m = (Map<String, Object>) object;

       builder.append("<").append(item).append(">");

       for(String key : m.keySet()){
           // todo: make sure these values are xml friendly
           builder.append("<").append(key).append(">")
                  .append(m.get(key))
                  .append("</").append(key).append(">");
       }

       builder.append("</").append(item).append(">");
   }

   public String getResultsAsXml(){
       StringBuilder result = new StringBuilder("<" + wrapper + ">")
               .append(builder)
               .append("</").append(wrapper).append(">");
       return result.toString();
   }

}

In the past I allways returned arraylist of hashmap and that works EXCLENT.

I now want to return xml. I saw some notes on xstream and it works but not
so well, I do not like the xml it makes.

Is there snipets or more ideas to help me?
