Use Java Pattern to extract word between HTML tag with attributes

Question

I am using the java Pattern & Matcher to extract the words between two tags.

My code is like:

final Pattern pattern = Pattern.compile("<([A-Za-z][A-Za-z0-9]*)\\b[^>]*>(.*?)</\\1>");
    List<String> topicArray = new ArrayList<String>();
    final Matcher matcher = pattern.matcher("<City count='1' relevance='0.304' normalized='Shanghai,China'>Shanghai</City>");
    while (matcher.find()) {
        topicArray.add(matcher.group(1));
    }

The system only gives me City as output instead of Shanghai. What's wrong with it?

Thanks

Use an HTML parsing library, that is what they are meant for. — Danny, Mar 20 '14 at 16:27

You can try the next:

private static final Pattern REGEX_PATTERN = 
        Pattern.compile("<[^>]*>([^<>]*)<[^>]*>");

public static void main(String[] args) {
    String input = "<City count='1' relevance='0.304' normalized='Shanghai,China'>Shanghai</City>";

    System.out.println(
        REGEX_PATTERN.matcher(input).replaceAll("$1")
    );  // prints "Shanghai"
}

Yes, it worked. Is there a way to check the tags within a tag? E.g. Shanghai – Xingsheng Guo Mar 20 '14 at 16:37
