XOM (XML Object Model) is a tree based java API for processing XML by taking the best ideas from SAX and DOM. It is simple, fast and easy to use. This requires the library xom-1.2.7.jar to be in classpath. The following example shows replacing a child element with a new element.

    Element dobChild = null;
    for (int i = ; i < students.size() ; i ++) {
      ageChild = students.get(i).getFirstChildElement("age");
      if (ageChild != null) {
        dobChild = new Element("dob");
        dobChild.appendChild(new Date().toString());
        //Replace 'age' element with 'dob' element
        students.get(i).replaceChild(ageChild, dobChild);
