This page shows how to port to Sparta from a standard DOM application. Many of the class names and method names are the same and so if you are lucky your code will not have to change much; this page lists the exceptions.

In the following: d is a Document variable, e is an Element variable, t is a Text variable, and n is a Node variable (any of the previous 3).

 

Standard DOM	Sparta DOM
import import org.w3c.dom.*	import com.hp.hpl.sparta.*
d = DocumentBuilderFactory .newInstance() .newDocumentBuilder() .newDocument()	d=new Document()	Sparta uses concrete classes
e = d.createElement(tagName)	e = new Element(tagName)	ditto
t = d.createTextNode(string)	t = new Text(string)	ditto
e = d.getDocumentElement() e = (Element)document.getFirstChild()	e = d.getDocumentElement()	The W3C provides two different ways of getting the same thing. Sparta provides just one way.
e.getTagName() e.getNodeName()	e.getTagName()	ditto
t.getData() t.getNodeValue()	t.getData()	ditto
if(n.getNodeType()==Node.ELEMENT_NODE)	if(n instanceof Element)	the W3C DOM is language independent; with Sparta you can use Java type info
NamedNodeMap attrs = e.getAttributes()	Enumeration attrNames = e.getAttributeNames()	Sparta attributes are not a Node sub-class; instead an element has a set of String name-value pairs.
e.getAttributes().getNamedItem("foo")	e.getAttribute("foo")	ditto
e.getElementsByTagName(tagName)	e.xpathSelectElements("//"+tagName)
SAXException	DOMException
d = DocumentBuilderFactory .newInstance() .newDocumentBuilder() .parse(file)	d = Parser.parse(file)
DOMSource(d)	DOMSource(DocumentImpl.wrapper(d))	To use Sparta with classes such as [javax.xml.transform.dom.DOMSource] which expect W3C documents use the wrapper method of [hp.hpl.agile.thermopylae.DocumentImpl] to covert from Sparta to W3C.
