Regular Expression Split XML in Java

Question

I want to split some XML text into parts:

xmlcontent = "<tagA>text1<tagB>text2</tagB></tagA>";

In C# i use

string[] splitedTexts = Regex.Split(xmlcontent, "(<.*?>)|(.+?(?=<|$))");

The result is

splitedTexts = ["<tagA>", "text1", "<tagB>", "text2", "</tagB>", "</tagA>"]

How can do it in Java?

I have tried

String[] splitedTexts = xmlcontent.split("(<.*?>)");

but the result is not like my expecting.

The parameter to split defines the delimiter to split at. You seem to want to find matches. — Holger

@Minh Le: You can use the regex package to find matches or refine the pattern to find delimiters as in my answer. — Holger

The parameter to split defines the delimiter to split at. You want to split before < and after > hence you can do:

String[] splitedTexts = xmlcontent.split("(?=<)|(?<=>)");

If you want to use Regex:

public static void main(String[] args) {
    String xmlContent = "<xml><tagA>text1</tagA><tagB>text2</tagB></xml>";
    Pattern pattern = Pattern.compile("(<.*?>)|(.+?(?=<|$))");
    Matcher matcher = pattern.matcher(xmlContent);
    while (matcher.find()) {
        System.out.println(matcher.group());
    }
}
