getting substring regex java

Question

I have this kind of line: <a href="/verona/4mktg-for-marketing.8526695" title="4MKTG FOR MARKETING SRL">4MKTG FOR MARKETING <strong>SRL</strong> </a>

I need the field's title. I splitted the string by 'title="' then checked if it matches with this regex: "[0-9A-Z /.]{3,}" . But it doesnt work...

The field contains only digits, capital letters, spaces and dots

Thank you

Davide

do you have to use a regex? If not, can just find where "title=\"" starts and take substring from where title" ends to next double quote. — DBug

Instead of using a regular expression, you should use JSoup when dealing with HTML.

Document doc = Jsoup.parse(html);
Element links = doc.select("a");
for (Element l : links) {
    // grab the title attribute value
    System.out.println(l.attr("title"));
}

agreed, anytime when parsing a known format (html, xml, json) don't use RegEx

If you need to do it with regex (and using java.util.regex, see this answer considering PERL-like regexes in Java):

str = '<a href="/verona/4mktg-for-marketing.8526695" title="4MKTG FOR MARKETING SRL">4MKTG FOR MARKETING <strong>SRL</strong> </a>';
str = str.replaceAll('.* title="([\s\.A-Z0-9]+)".*', "$1");
