for(Element itemElement : sourceElements){
    itemElement.elementTextTrim("name");
    itemElement.elementTextTrim("desc");
    List<Elements> subList = itemElement.elements("sub");
    //Can't go into loop because subList.size() value is 0

Below code is working fine for me .

    SAXReader reader = new SAXReader();
    Document document = reader.read("a.xml");
    Element rootElement = document.getRootElement();        
    List<Element> list =  rootElement.elements("std");

    for (Element element : list) {
        System.out.println(element.elementTextTrim("name"));
        List<Element> sublist =  element.elements("sub");
        for (Element element2 : sublist) {
            System.out.println(element2.elementTextTrim("sub1"));
            System.out.println(element2.elementTextTrim("sub2"));
        }

    }

For below a.xml :-

<content>
     <std>
        <name>name1</name>
        <desc>desc1</desc>
        <sub>
           <sub1>22</sub1>
           <sub2>223</sub2>
        </sub>
     </std>
</content>
