<div class=\"customclass recordwidget comments-section\" style=\"margin-bottom:8px;  background-color:#f8f8f8; border-bottom:1px solid #f01928;border-top:1px solid #f01928; padding:8px; line-height:1.1;\"><div class=\"headingcontent\"><b style=\"font-size:15px;\">Rob</b> <b>2/9/2018</b> 8:43:5 </div> <div class=\"recordwidget-content\"><p>Comments to modified date</p>\n </div> </div><div class=\"customclass recordwidget comments-section\" style=\"margin-bottom:8px;  background-color:#f8f8f8; border-bottom:1px solid #f01928;border-top:1px solid #f01928; padding:8px; line-height:1.1;\"><div class=\"headingcontent\"><b style=\"font-size:15px;\"> om</b> <b>4/25/2018</b> 8:8:32 </div> <div class=\"recordwidget-content\"><p>Hello World</p>\n </div> </div><div class=\"customclass recordwidget comments-section\" style=\"margin-bottom:8px;  background-color:#f8f8f8; border-bottom:1px solid #f01928;border-top:1px solid #f01928; padding:8px; line-height:1.1;\"><div class=\"headingcontent\"><b style=\"font-size:15px;\"> Perry</b> <b>4/26/2018</b> 4:1:58 </div> <div class=\"recordwidget-content\"><p>&nbsp; &nbsp; bbb&nbsp; &nbsp; &nbsp;&nbsp;</p>\n </div> </div>

If html contain only one div then that is last div need to modify.Please let me know how can achieve this in Java.

Answer 1

I assume your main objective is to store the data into database and make this dynamic for various purposes / elements.

Step 1) First grab the DIV and stored it to a variable

Step 2) Transform the DIV to XML / JSON (incl of data type) based on a schema. Don't forget to handle failure scenario

Step 3) Apply your business logic or any other modifications

Step 4) Use XML path or Json Path to get the data you want to store and iterate the same

All the above could be achieved by java code
