使用Jsoup从HTML页面中的元素中提取文本

Question

I am extracting texts from the following html element

<span class="adr" style="float: none !important;">
     <span class="street-address" style="float: none !important;">18, Jawaharlal Nehru
       Road,
     </span>
     <span  style="float: none !important;" class="estb_addr-HeadingTxt">
       <a style="float: none !important;"   href="http://kolkata.burrp.com/area/park-street" class="locality">&nbsp;Park Street</a></span>
       ,&nbsp;Kolkata<span class="region" style="display: none;">Kolkata
     </span>
</span>

For that I wrote the following piece of code:

for (Element element : doc.getAllElements()) 
{
        for(Element childelem: element.children())
           {
             if (childelem.hasText() && !childelem.ownText().isEmpty()) 
                {

                     String currText=childelem.ownText();
                     System.out.print(currText+" ");

                  }

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

Ideally the output should be . But it is giving and . I can understand that the output is basically inorder traversal of the DOM tree rooted at outer <span>. But I don't know exactly how to achieve that by Jsoup, where a DOM tree for an element in a HTML page has arbitrary levels of nesting.

Any help would be appreciated. Thank you.

Use either DOM navigation or CSS-selector syntax to do the task, do not loop through all Elements .

Element adr = doc.select("span.adr").first().
System.out.println(adr.text());
