本文介绍了如何使用DOM(JAVA)在XML文档中添加Doctype的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在java中使用DOM创建了一个XML文档。我无法添加doctype。我想要像这样的doctype。
I have created a XML document using DOM in java. I am unable to add doctype. I want the doctype like this.
<!DOCTYPE IndInfo PUBLIC "EDAFileSomething" "EDAFileSomething_2_0.dtd">
这是文档创建代码。
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument();
这是变形金刚对象代码。
Here is the Transformer Object Code.
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = null;
try {
transformer = transformerFactory.newTransformer();
} catch (TransformerConfigurationException ex) {
Logger.getLogger(Reader.class.getName()).log(Level.SEVERE, null, ex);
}
DOMSource source = new DOMSource(doc);
try {
StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);
} catch (TransformerException ex) {
Logger.getLogger(Reader.class.getName()).log(Level.SEVERE, null, ex);
}
System.out.println("File saved!");
推荐答案
您可以使用DOM构建doctype并设置doctype作为输出属性。
You can construct the doctype with the DOM and set the doctype as an output property.
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");
DOMImplementation domImpl = document.getImplementation();
DocumentType doctype = domImpl.createDocumentType("doctype",
"-//Oberon//YOUR PUBLIC DOCTYPE//EN",
"YOURDTD.dtd");
transformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC, doctype.getPublicId());
transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, doctype.getSystemId());
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(new File(database));
transformer.transform(source, result);
