jsoup遍历html,如何使用Jsoup遍历HTML树？
您可以使用以下代码：
public class JsoupDepthFirst {
private static String htmlTags(Document doc) {
StringBuilder sb = new StringBuilder();
htmlTags(doc.children(), sb);
return sb.toString();
}
private static void htmlTags(Elements elements, StringBuilder sb) {
for(Element el:elements) {
if(sb.length() > 0){
sb.append(",");
}
sb.append(el.nodeName());
htmlTags(el.children(), sb);
sb.append(",").append(el.nodeName());
}
}
public static void main(String... args){
String s = "
this is head this is body";Document doc = Jsoup.parse(s);
System.out.println(htmlTags(doc));
}
}
您可以使用以下代码： public class JsoupDepthFirst { private static String htmlTags(Document doc) { StringBuilder sb = new StringBuilder(); htmlTags(doc.children(), sb); return sb.toString(); } private static void htmlTags(Elements elements, StringBuilder sb) { for(Element el:elements) { if(sb.length() > 0){ sb.append(","); } sb.append(el.nodeName()); htmlTags(el.children(), sb); sb.append(",").append(el.nodeName()); } } public static void main(String... args){ String s = "this is head this is body"; Document doc = Jsoup.parse(s); System.out.println(htmlTags(doc)); } }
