Creating a document in Java

I am creating a KML document in Java. Inside of it i have to add many similar elements, resulting in the need to add a function, where I can pass needed arguments.

The problem is that when I try to add a part of the document into the main document it shows error, or creates malformed document. Here's a code snippet:

Element style = doc.createElement("Style");
style.setAttribute("id", "green");
dnode.appendChild(style);
Element polyStyle = doc.createElement("PolyStyle");
style.appendChild(polyStyle);
Element color = doc.createElement("color");
color.appendChild(doc.createTextNode("5014F064"));
polyStyle.appendChild(color);
Element iconStyle = doc.createElement("IconStyle");
style.appendChild(iconStyle);
color = doc.createElement("color");
color.appendChild(doc.createTextNode("5014F064"));
iconStyle.appendChild(color);

Element "dnode" is a Document element inside xml. I want to try something like this:

doc.appendChild(addFeatureStyle("red", "501400FA"));

Called three times with different parameters but have no idea how to include it. I want to add function written above, calling the code snippet.

Should the function "addFeatureStyle" return element, or a string, or something else?

I'm not sure I understand your question, but I'll try to answer:

Should the function "addFeatureStyle" return element, or a string, or something else?

You're calling the method appendChild() with the value returned by addFeatureStyle("red", "501400FA") as argument.

The documentation of appendChild() shows that it takes a Node as argument. So the return type of addFeatureStyle() can't be a String: String doesn't implement the Node interface. The return type of addFeatureStyle() must be Node, or a class implementing Node, or an interface extending Node.
