使用XML模板填充數據

java 代碼如下：

public class GeneralXML {
	public static String readFile(String filePath) {
		StringBuffer sb = new StringBuffer();
		File file = new File(filePath);
		FileReader fr = null;
		try {
			fr = new FileReader(file);
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		}
		BufferedReader br = new BufferedReader(fr);

		String strLine = "";
		try {
			while ((strLine = br.readLine()) != null) {
				sb.append(strLine);
				sb.append("\n");
			}
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			try {
				fr.close();
				br.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		return sb.toString();
	}
	
	public static void main(String[] args) {
		final String  head = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>\n";
		final String root_start = "<root>";
		final String root_end = "</root>";
		StringBuffer sb = new StringBuffer();
		sb.append(head);
		sb.append(root_start);
		MessageFormat mf = new MessageFormat(readFile("src/main/resources/template.xml"));
		sb.append(mf.format(new Object[] { "11", "12", "13", "14"}));
		sb.append(mf.format(new Object[] { "21", "22", "23", "24"}));
		sb.append(root_end);
		System.out.println(sb.toString());
	}
}

xml模板如下：

<study name="{0}">
	<one>{1}</one>
	<two>{2}</two>
	<three>{3}</three>
</study>

在實際應用中，我們可以將代碼中的xml的頭和尾都放在xml模板中，而代碼就可以省略 StringBuffer了
