Creating and Modifying XML Documents - Beginning Java - page 1302

putting it into a method in the Element class that you call with the appropriate XML element name as an
argument:

protected org.w3c.dom.Element createPointTypeElement(Document doc,
String name,
String xValue,
String yValue) {
org.w3c.dom.Element element = doc.createElement(name);

Attr attr = doc.createAttribute("x"); // Create attribute x

attr.setValue(xValue); // and set its value

element.setAttributeNode(attr); // Insert the x attribute

attr = doc.createAttribute("y"); // Create attribute y

attr.setValue(yValue); // and set its value

element.setAttributeNode(attr); // Insert the y attribute

return element;

}

This creates an element with the name specified by the second argument, so you can use this in another
method in the Element class to create a node for a <position> element:

// Create the XML element for the position of a sketch element
protected org.w3c.dom.Element createPositionElement(Document doc) {
return createPointTypeElement(doc, "position",
String.valueOf(position.x),
String.valueOf(position.y));

}

You are able to create <endpoint> or <point> nodes in the same way in methods that you implement in
the subclasses of Element .
You can create a <bounds> element like this:

protected org.w3c.dom.Element createBoundsElement(Document doc) {
org.w3c.dom.Element boundsElement = doc.createElement("bounds");
