html - Jsoup: Safe Elements.get(0) -

the following snippet of code extracts 1 , 1 element, first element:

  string linkhref = "";   string linktext = "";   elements links = div.getelementsbytag("a");   (element link : links) {     linkhref = link.attr("href");     linktext += link.text();                   break;   }     

this cumbersome code compared concise links.get(0) has 1 important feature: not throw indexoutofboundexception if elements empty. instead, leave strings empty.

i can encapsulate own function it's hard me believe jsoup doesn't have such function (i prefer using library function on "re-inventing wheel" as possible). searched documentation couldn't find any.

do know whether such "safe elements.get(0)" exists in jsoup?

elements.first() returns first element elements, or null if empty.

also can use elements.isempty() check if matches selector.

e.g., depending on trying do:

element link = div.select("a").first(); if (link != null) {   string href = link.attr("href");   string text = link.text(); }
