Java String.replaceAll 正则 .*表示所有字符

package test;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import static java.lang.System.out;

public class testString {
	public static void main(String arg [])
	{
		File file = new File("e:/widget config sample.xml");
		FileInputStream fileInputStream;
		BufferedReader reader = null;
		try {
			fileInputStream = new FileInputStream(file);
			reader = new BufferedReader(new InputStreamReader(fileInputStream));
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		String xmlString = "";
		String temp ;
		try {
			while((temp = reader.readLine())!=null )
			{
				xmlString += temp;
			}
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		out.println(xmlString);
		
		String one = "abcdefghij.klmnop.qrstuvwxyz";
		String two = "abc.defghij.klmnop.qrstuvwxyz";
		
		xmlString = xmlString.replaceAll(".*.<entries ws='", "").replaceAll("' />.*</widgets>", "/ws/maps") ;
		one = one.replaceAll("cde.*xy", "");
		two = two.replaceAll("cde.*xy", "");
		
		out.println(xmlString);
		out.println(one);
		out.println(two);
		
	}
}

输出结果:

<?xml version="1.0" encoding="UTF-8"?><widgets>	<widget name='employee'><datasource name='titles' type='map'><entries ws='http://www.sina.com'/></datasource></widget></widgets>
http://www.sina.com/ws/maps
abz
abc.defghij.klmnop.qrstuvwxyz

.表示任何字符, *表示0个-无穷个


replaceAll第一个参数是正则，split也是使用正则
