java 读取 GBK 编码的XML字串

try {
			InputStream is = new ByteArrayInputStream(xml.getBytes("GBK"));
			DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
			dbf.setIgnoringElementContentWhitespace(true);
			DocumentBuilder db = null;
			db = dbf.newDocumentBuilder();
			Document doc = db.parse(is);
			
		} catch (Exception ex) {
			ex.printStackTrace();
		}

另一种读取方式:

private static Map getWholeXMLKeyValue(String file) {
		Map sqlMap = new HashMap();
		try {
			Document document = parse(file);
			Element root = document.getRootElement();
			// 遍歷根節點(sql_config)的所有子節點

			for (Iterator iter = root.elementIterator(); iter.hasNext();) {
				Element element = (Element) iter.next();
				// 遍歷sqls節點的的所有子節點

				for (Iterator iterInner = element.elementIterator(); iterInner.hasNext();) {
					Element elementInner = (Element) iterInner.next();
					// 遍歷(domestic...)等節點的的所有子節點,并取得其鍵值對
					for (Iterator iterSub = elementInner.elementIterator(); iterSub.hasNext();) {
						Element innerSub = (Element) iterSub.next();
						sqlMap.put(element.getName() + "." + elementInner.getName() + "." + innerSub.getName(), innerSub.getStringValue());
					}
				}
			}
		} catch (DocumentException ex) {
			log.error("The resource file(" + file.toString() + ") was not found. ", ex);
		}
		return sqlMap;
	}

private static Document parse(String file) throws DocumentException {
		ClassLoader classLoader = null;
		SAXReader reader = new SAXReader();
		classLoader = Thread.currentThread().getContextClassLoader();
		Document document = reader.read(classLoader.getResourceAsStream(file));
		return document;
	}
