Questions about parsing while crawling using jsoup (Android)

I'm a beginner developer who wants to create an Android app. I have a question about parsing while crawly using jsoup.

The following code was written using the select method. Elements elements = doc.select("tr[tabinex=3]");
And then, as you can see in the screenshot, the Android screen shows all the prices of all the countries.

What I want is to parse only certain elements of a country like the blue circle. In this case, how should I put the factor in the select method?

When testing Java code, we recommend jshell or groovy(groovysh). Please refer to the code below.

The answer you want is table tr[tabindex=3] td:eq(1) together.

groovy:000> @Grab(group='org.jsoup', module='jsoup', version='1.11.3')
groovy:001> go
===> null
groovy:000> import org.jsoup.*
===> org.jsoup.*
groovy:000> import org.jsoup.select.*
===> org.jsoup.*, org.jsoup.select.*
groovy:000> doc = Jsoup.connect("https://eshop-prices.com/").get()
groovy:000> doc.select("table tr[tabindex=3]")
===> [<tr data-table-searchable="" tabindex="3">
 <th><a href="https://eshop-prices.com/games/379-1-2-switch">1-2-Switch</a></th>

===> [<td>€49,99</td>]
