Take the string regular substring

Question is this:
for an HTML page content, wherein the parsed all key-value pairs, where such type = "text", type attribute, text value, both as a key-value pair
as follows: <input type="text" class="s_ipt" name="wd" id="kw" maxlength="100" a="b" autocomplete="off">
get this problem we first thought was how to traverse, from start to finish how to take out all the sub-strings, symbols and how to eliminate them. First, the method of traversing like a long time, the result is not good enough, the following code, seeking to improve:

	public static void main(String[] args) {

		String zifu = "<input type=\"text\" class=\"s_ipt\" name=\"wd\" id=\"kw\" maxlength=\"100\" a=\"b\" autocomplete=\"off\">";
		
		String zfsz[] = new String[10];
		int a = 0;
		for (int i = 0; i < zifu.length(); i++) {
			
			if (' '==zifu.charAt(i)) {
				
				for (int j = i+3; j < zifu.length(); j++) {
					if (' '==zifu.charAt(j)||'>'==zifu.charAt(j)) {
						zfsz[a] = zifu.substring(i+1, j);
						String temp = zfsz[a].replaceAll("\\W+"," ");
						System.out.println(temp);
						a++;
						break;
					}
				}
			}
			
		}
	}

Think very hard, also wrote to burn the brain, and finally search for a moment about regular expressions, find the String class split method is to use regular expressions to split them into an array, with specific reference to the relevant API, I can not say here.
Code is modified as follows:

public static void main(String[] args) {
	String zifu = "<input type=\"text\" class=\"s_ipt\" name=\"wd\" id=\"kw\" maxlength=\"100\" a=\"b\" autocomplete=\"off\">";
	String regex0 = " ";
	//首先，我们以空格将字符串拆分成字符数组
	String[] result0 = zifu.split(regex0);
	//然后对所有字符数组中的非字母元素进行替换
	for (int i = 1; i < result0.length; i++) {
		regex0 = result0[i].replaceAll("\\W+", " ");
		System.out.println(regex0);
	}		
}

Ah, I am not looking at it more simple? There are better ways, can comment below, seek advice. .
