Question

I want to get the html contents from a website
and I use the jsoup(java open source ) ,to crwal a web site and get the elements with this code:

 Document doc = Jsoup.connect("http://bj.58.com/shangdi/zufang/0/").get();  
        Elements hrefs = doc.select("*");
        Elements hrefs2 = hrefs.select("td:lt(4)");  
        System.out.println(hrefs2);

and i get the result:

<td class="tc"><b class="pri">2100</b></td>
<td class="tc">ABCD</td>
<td class="tc">today</td>

or I edit this code(just add a “text()”in the last line ) :

 Elements hrefs2 = hrefs.select("td:lt(4)");  
 System.out.println(hrefs2.text());

and i get the result:

 2100 ABCD today 

but I really want to acheive is like this result:

   2100,ABCD,today 

is any way to add the comma into the result,so that easy to save the result into the database with csv file.

Answer 1

You can get an iterator over the resultant Elements from hrefs.select, and at that point you can do whatever you want with the list (i.e., format it however you wish).
