html怎样遍历两个日期之间的,Jsoup：如何获取2个标题标签之间的所有html

小编典典

如果要获取和处理两个连续h1标签之间的所有元素，则可以处理同级对象。这是一些示例代码：

public static void h1s() {

String html = "" +

"

" +

"

" +

"

title 1

" +

"

hello 1

" +

"

"

" +

"

hello" +

"

world" +

"

1" +

"

" +

"

" +

"

title 2

" +

"

hello 2

" +

"

"

" +

"

hello" +

"

world" +

"

2" +

"

" +

"

" +

"

title 3

" +

"

hello 3

" +

"

"

" +

"

hello" +

"

world" +

"

3" +

"

" +

"

" +

"" +

"";

Document doc = Jsoup.parse(html);

Element firstH1 = doc.select("h1").first();

Elements siblings = firstH1.siblingElements();

List elementsBetween = new ArrayList();

for (int i = 1; i < siblings.size(); i++) {

Element sibling = siblings.get(i);

if (! "h1".equals(sibling.tagName()))

elementsBetween.add(sibling);

else {

processElementsBetween(elementsBetween);

elementsBetween.clear();

}

}

if (! elementsBetween.isEmpty())

processElementsBetween(elementsBetween);

}

private static void processElementsBetween(

List elementsBetween) {

System.out.println("---");

for (Element element : elementsBetween) {

System.out.println(element);

}

}
