1.先把字符串进行匹配
2.从字符串中得到想要的值
public void testRegex() {
String msg = "Rect(x1=\"0\" y1=\"0\" x2=\"416\" y2=\"416\")Rect(x1=\"1\" y1=\"2\" x2=\"413\" y2=\"414\")";
List<String> textList = new ArrayList<String>();
Pattern pattern = Pattern.compile("(x1=\"[^\"]*\"\\s*y1=\"[^\"]*\"\\s*x2=\"[^\"]*\"\\s*y2=\"[^\"]*\")");
Matcher matcher = pattern.matcher(msg);
while (matcher.find()) {
textList.add(matcher.group(1));
}
for (String text : textList) {
try {
System.out.println(text);
System.out.println(getValue(text,"x1"));
System.out.println(getValue(text,"y1"));
System.out.println(getValue(text,"x2"));
System.out.println(getValue(text,"y2"));
}
catch (Exception ex)
{}
}
}
public static String getValue(String source,String key) {
if (isEmpty(source)) {
return null;
}
Pattern p = Pattern.compile("\\b" + key + "\\s*=\\s*\"([^\"]*)\"");
Matcher m = p.matcher(source);
if (m.find()) {
return m.group(1);
}
return null;
}
public static boolean isEmpty(String str) {
return str == null || str.length() == 0;
}输出：
注意，匹配到的字符串并不含括号，如果想要匹配括号，那么应该这么写
Pattern pattern = Pattern.compile("(\\(x1=\"[^\"]*\"\\s*y1=\"[^\"]*\"\\s*x2=\"[^\"]*\"\\s*y2=\"[^\"]*\"\\))");
