In fact, you'll write an XML dossier just by creating a series of print calls, printing the weather, attributes, and textual content content material, yet that might now not be a good suggestion. The code is very tedious, and you may simply make error in case you don’t be aware of detailed symbols (such as " or <) within the characteristic values and textual content content material. a greater strategy is to accumulate a DOM tree with the contents of the rfile after which write out the tree contents. the subsequent sections speak about the main points. 2. 7. 1. records with out Namespaces to construct a DOM tree, you begin out with an empty rfile. you may get an empty record by way of calling the newDocument approach to the DocumentBuilder type: record document = builder. newDocument(); Use the createElement approach to the record classification to build the weather of your rfile: click on the following to view code snapshot aspect rootElement = document. createElement(rootName); aspect childElement = document. createElement(childName); Use the createTextNode solution to build textual content nodes: textual content textNode = document. createTextNode(textContents); upload the basis aspect to the rfile, and upload the kid nodes to their mom and dad: document. appendChild(rootElement); rootElement. appendChild(childElement); childElement. appendChild(textNode); As you building up the DOM tree, you can also have to set point attributes. easily name the setAttribute approach to the aspect classification: rootElement. setAttribute(name, value); 2. 7. 2. files with Namespaces should you use namespaces, the method for making a rfile is a little various. First, set the builder manufacturing facility to be namespace-aware, then create the builder: click on the following to view code photograph DocumentBuilderFactory manufacturing facility = DocumentBuilderFactory. newInstance(); manufacturing facility. setNamespaceAware(true); builder = manufacturing unit. newDocumentBuilder(); Then use createElementNS rather than createElement to create any nodes: click on the following to view code photograph String namespace = "http://www. w3. org/2000/svg"; point rootElement = document. createElementNS(namespace, "svg"); in case your node has a certified identify, with a namespace prefix, then any valuable xmlns-prefixed attributes are created instantly. for instance, if you would like SVG within XHTML, you could build a component like this: aspect svgElement = document. createElement(namespace, "svg:svg") whilst the point is written, it becomes if you want to set point attributes whose names are in a namespace, use the setAttributeNS approach to the point type: rootElement. setAttributeNS(namespace, qualifiedName, value); 2. 7. three. Writing files a little apparently, it isn't really easy to jot down a DOM tree to an output circulate. the best strategy is to take advantage of the Extensible Stylesheet Language alterations (XSLT) API. for additional information approximately XSLT, flip to part 2. eight, “XSL Transformations,” on p. 173. at once, think of the code that follows a magic incantation to provide XML output. We follow the do-nothing transformation to the record and catch its output.
