当Jsoup解析仅包含“ 0”的HTML标记时，将返回null吗？

Question

I use jsoup-1.6.0，parse html tag string, that only include string content "0", but jsoup return null, I understand...

examply:

String html = "<span>0</span>";
Document doc = Jsoup.parse(html);
Elements eles = doc.getElementsByTag("span");
Element span = eles.get(0);
System.out.println(span.hasText());//false
System.out.println(span.ownText());//null, but I hope the result is "0"

It's why?

Answer:

It should be a bug, binary_runner says jsoup-1.3.3 works well, I test jsoup-1.5.2 works well too. so, I decide use jsoup-1.5.2 .

Thanks binary_runner!

Answer 1

This is a bug in jsoup 1.6.0 caused by an incorrect null check in the new HTML parser implementation.

I have fixed the issue and it will be available in 1.6.1 , which I'll in the next couple of days.

Answer 2

I'm not sure. probably, i guess, it's a Jsoup's bug. I could a with following code.

String html = "<span>a</span>";
Document doc = Jsoup.parse(html);
Elements eles = doc.getElementsByTag("span");
Element span = eles.get(0);
System.out.println(span.hasText());//true
System.out.println(span.ownText());//"a"

Answer 3

显然，一个错误可以与JSoup 1.3.3一起很好地工作。
