How to separate a result from "td" element came from 2 different tables

I'm getting data from a website, this website contains 2 tables

1- warranty date
2- upgrade warranty date

when I select elements by "td" and try to get the start date by sub-string it I get the result as below

2015-01-01
2015-01-01

I want to separate the above 2 dates so that I can use each one alone. I want them to be considered as one line

2015-01-012015-01-01

and then I can sub-string each one alone to use it as I need. I tried to use (.toString()) and then scanner and then sub-string, but it does the sub-string for both example, if my sub-string is for indexes 1,3, the result will be

201
201

but I want it to be

201
2015-01-01

so the second line would be considered as different one ! my code is:

if(tableTitle.contains("Warranty and Service Information:")) {
theElements = ele.select("td");
String contenent1;
contenent1 = theElements.toString();
// this is not the scanner I mentioned above
Scanner sr1 = new Scanner(contenent1);
startDate = contenent1.substring(4, 14);
endDate = contenent1.substring(24, 34);
System.out.println(startDate);
}

and the result is:

2012-07-04
2012-07-04

here are 2 images to show the tables, the table upgrade warranty appears in rare cases only, but when it appears there is a problem to show each result in one line only.

when there is no upgrade table

and here is when the upgrade table appear

and the source codes are:
