string feedxmlstring = "<entry><title>title 1</title><source><title>title 2</title></source></entry>";     document feedxml = jsoup.parse(feedxmlstring);      nodetraversor feedxmltraversor = new nodetraversor(new nodevisitor() {            @override           public void tail(node node, int depth) {               if (node instanceof element) {                    string tagname = ((element) node).tagname();                                       string parenttagname = ((element) node).parent().tagname();                    if (tagname.equals("title")) {                                 if (parenttagname.equals("entry")) {                           string title = ((element) node).owntext();                           system.out.println(title);                       }                   }               }           }            @override           public void head(node node, int depth) {            }         });     feedxmltraversor.traverse(feedxml.body());

output is

title 1 title 2

i want title 1. i'm working under assumption parent tag of second title <source>, reason jsoup seems think <entry>

thanks!

thanks!

why don't use selector part of jsoup api? it's much easier use, it's cleaner, , i'm willing bet that's faster well. i'd use this:

//the line had document doc = jsoup.parse(feedxmlstring);  //this titles elements elems = doc.select("title");  //and can proceed in various ways: string title1stway = elems.first().text(); string title2ndway = elems.get(0).text();

take here: jsoup selector api
