&x变换为汉字

&#x转换为汉字

路遇&#x，研究一下发现就是Unicode不同之处在于%u换成了&#x，还有就是后面多了个分号。

给出转换方法,自己留着备用:

 

       
	public static StringBuffer decodeUnicode(String dataStr) {
		dataStr=dataStr.replace("&#x", "\\u");
		final StringBuffer buffer = new StringBuffer();
		String tempStr = "";
		String operStr = dataStr;
		if (operStr != null && operStr.indexOf("\\u") == -1)
			return buffer.append(operStr);
		if (operStr != null && !operStr.equals("")
				&& !operStr.startsWith("\\u")) {
			tempStr = operStr.substring(0, operStr.indexOf("\\u"));
			operStr = operStr.substring(operStr.indexOf("\\u"), operStr
					.length());
		}
		buffer.append(tempStr);
		while (operStr != null && !operStr.equals("")
				&& operStr.startsWith("\\u")) {
			tempStr = operStr.substring(0, 6);
			operStr = operStr.substring(7, operStr.length());
			String charStr = "";
			charStr = tempStr.substring(2, tempStr.length());
			char letter = (char) Integer.parseInt(charStr, 16);
			buffer.append(new Character(letter).toString());
			if (operStr.indexOf("\\u") == -1) {
				buffer.append(operStr);
			} else { 
				tempStr = operStr.substring(0, operStr.indexOf("\\u"));
				operStr = operStr.substring(operStr.indexOf("\\u"), operStr
						.length());
				buffer.append(tempStr);
			}
		}
		return buffer;
	}
