如何在运行时在smooks配置中为"createOnElement“赋值？

import java.io.IOException;

public class SmooksExample {
    public static void main(String[] args) throws IOException, SAXException, SmooksException {
        // 创建Smooks实例
        Smooks smooks = new Smooks();

        // 配置Smooks的基本设置
        smooks.setReaderConfig(new UNEdifactReaderConfigurator("urn:org.milyn.edi.unedifact:d96a-mapping:*"));

        // 创建Smooks配置对象并加载配置文件
        Smooks smooksConfig = new Smooks();
        smooksConfig.setConfig(new StreamSource("smooks-config.xml"));

        // 获取配置对象中的"createOnElement"属性并赋值
        String createOnElement = "exampleElement";
        smooksConfig.setCreateOnElement(createOnElement);

        // 将配置对象应用到Smooks实例中
        smooks.setConfiguration(smooksConfig);

        // 输入数据
        String input = "<exampleElement>Example Data</exampleElement>";

        // 使用Smooks实例对输入数据进行处理和转换
        ExecutionContext executionContext = smooks.createExecutionContext();
        JavaResult result = new JavaResult();
        smooks.filterSource(executionContext, new StringSource(input), result);

        // 输出结果
        System.out.println(result.getBean(createOnElement));
    }
}
