使用XML模板填充数据

java 代码如下：

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());
	}
}

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

在实际应用中，我们可以将代码中的xml的头和尾都放在xml模板中，而代码就可以省略 StringBuffer了
