How to split XML tags into key and value pairs in Java

I have a text file which contains different XML tags. I need to split these tags into key and value pairs. For example the following tag should be changed to Version:1.5

<manifest:Version>1.5</manifest:Version>

Expected output: Version:1.5

Is there any way to do this without using XML Parser?

Since you already mentioned you don't want to use any xml-parser here is a sample code which will work in you case-

import java.util.Arrays;
import java.util.List;

public class BadXmlParser {
    public static void main(String[] args) {
        List<String> tags = Arrays.asList("<manifest:Name>java</manifest:Name>", "<manifest:Version>1.8</manifest:Version>");
        tags.forEach(tag -> {
            String key = tag.substring(tag.indexOf(":") + 1, tag.indexOf(">"));
            String value = tag.substring(tag.indexOf(">") + 1, tag.indexOf("</"));
            System.out.println(key + ":" + value);
        });
    }
}

Never recommended approach to use in prod.

Note: You should put validation logic by you own this is just parsing logic provided
