本文介绍如何使用Java创建一个用于CDN上传请求的XML文件。该过程涉及创建多个XML元素，并设置特定属性来构建完整的XML结构。文章详细展示了如何为每个元素添加必要的内容，并最终将构建好的XML转换为字符串形式。

Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
Element cndXml = doc.createElement("CDN_XML");
Element askForUpload = doc.createElement("ask_for_upload");
Element adi = doc.createElement("ADI");
Element metadata = doc.createElement("Metadata");
CommonUtil.amsXml(doc, metadata, 1, mapList.get(i));
Element appData = doc.createElement("App_Data");
appData.setAttribute("App", "VOD");
metadata.appendChild(appData);
appData.setAttribute("Name", "Metadata_Spec_Version");
metadata.appendChild(appData);
appData.setAttribute("Value", "CableLabsVOD1.1");
metadata.appendChild(appData);
adi.appendChild(metadata);
askForUpload.appendChild(adi);
cndXml.appendChild(askForUpload);
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
transformer.setOutputProperty("version", "1.0");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
DOMSource source = new DOMSource(apis);
StringWriter strReturn = new StringWriter();
transformer.transform(source, new StreamResult(strReturn));
retString = strReturn.toString();
