Parse a map in digester

Question

I have a string of XML as

<ShowPercentage>     
    <SPGLevel>       
        <Level> 1 </Level>   
        <percentage>40</percentage>      
    </SPGLevel>
    <SPGLevel>       
        <Level> 2 </Level>
        <percentage>60</percentage>      
    </SPGLevel>
</ShowPercentage>

The SPG Level is repeatable. This is a map with key=Level and value=percentage

I want to parse this XML using Digester. Can anyone help me get started?

The answer may look like the following code, but I didn't test this:

public class SampleDigester
{
  private Map<String, String> map = new HashMap<String, String>();

  public void run() throws IOException, SAXException {    
    Digester digester = new Digester();
    digester.push(this);

    digester.addCallMethod("ShowPercentage/SPGLevel", "addKey", 2);
    digester.addCallParam("ShowPercentage/SPGLevel/Level", 0);
    digester.addCallParam("ShowPercentage/SPGLevel/percentage", 1);
    digester.parse("input.xml");

  }

  public void addKey(String key, String value) {
    map.put(key, value);
  }

}
