问我import javax.xml.parsers.DocumentBuilder
import javax.xml.parsers.DocumentBuilderFactory
//构造
public XMLUtil(String name) throws ParserConfigurationException {
filename = name
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance()
builder = factory.newDocumentBuilder()
document = builder.newDocument()
}
/**
* 保存到文件
*/
public void toSave() {
try {
TransformerFactory tf = TransformerFactory.newInstance()
Transformer transformer = tf.newTransformer()
DOMSource source = new DOMSource(document)
transformer.setOutputProperty(OutputKeys.ENCODING, "GB2312")
transformer.setOutputProperty(OutputKeys.INDENT, "yes")
PrintWriter pw = new PrintWriter(new FileOutputStream(filename))
StreamResult result = new StreamResult(pw)
transformer.transform(source, result)
} catch (TransformerException mye) {
mye.printStackTrace()
} catch (IOException exp) {
exp.printStackTrace()
}
}
