用jsoup解析字符串

Question

我有一根绳子：

String HTMLtag="<xml><xslt><xhtml><whitespace><line-breaks>";

我想得到5个字符串: xml、xslt、xhtml、空格和换行。

Answer 1

就像这样

String html = "<xml><xslt><xhtml><whitespace><line-breaks>";
Document doc = Jsoup.parse(html, "", Parser.xmlParser());
for (Element e : doc.getAllElements()) {
    System.out.println(e.tagName());
}

Ouput

#root   --> This is the root element that is created by jsoup, you can ignore it.
xml
xslt
xhtml
whitespace
line-breaks

编辑

String html = "<xml><xslt><xhtml><whitespace><line-breaks>";
Document doc = Jsoup.parse(html, "", Parser.xmlParser());
for (Element e : doc.getAllElements()) {
    String tag = e.tagName();
    if(!tag.equalsIgnoreCase("#root"))
        System.out.println(tag);
}
