Question

i tried to split a string looks like this

<a><b><c></c></b></a>

with java using the following code

String[] s =input.split("[<>]+");
System.out.println(Arrays.toString(s));

and this was the output

[, a, b, c, /c, /b, /a]

i don’t know what should i do to get rid of this empty string in the beginning of the resulting array.

any suggestions ?

Answer 1

There is an alternative method using regular expression matching:

String input = "<a><b><c></c></b></a>";

Pattern p = Pattern.compile("<(.+?)>");
Matcher m = p.matcher(input);

ArrayList<String> s = new ArrayList<String>();

while(m.find())
    s.add(m.group(1));

System.out.println(s.toString());

Output:
[a, b, c, /c, /b, /a]
