Question

How can I create new Element each time when (i) will be incremented:

for(int i = 0; i < 10; i++)
{
    Element child = doc.createElement("xxx");
    root.setAttribute("x", i * "xx");
    doc.appendChild(child);
}

Answer 1

Using java

    Element child = null;        

    for(int i = 0; i < 10; i++)
    {
      child = doc.createElement("xxx" + i);//you can write a method with int parameter to get element name from somewhere else 

      doc.appendChild(child);
    }

I hope this is what you wanted, by the way for text nodes you should use doc.createTextNode("A")
