<tr id="Row7d6251f9-f6ea-48bb-90fb-356725307245" class="Schedule-row -1 new odd" data-Schedule-id="-1">

I have this code. Basically I have a table with a lot of rows. Using Webdriver (Java) I can click a button and then a new row will be generated with random ID (In this case Row7d6251f9-f6ea-48bb-90fb-356725307245).

Case 1: I know that the first row will always be fixed number Row00000. I can use while loop and increment the number until I don't get Row00015. That means the last fixed row number is Row00014. I can take take Row00014 as my base reference and the next parent is what I want.

How to jump to next parent (ignoring all children belonging to Row00014) and get the newly randomly generated ID ?

Case 2: In case the table is empty, whenever Webdriver clicks a button, it creates a newly randomly row id.

<table class="ui-table Schedule detailed">
<thead>
<tbody>
<tr id="Row7d6251f9-f6ea-48bb-90fb-356725307245" class="Schedule-row -1 new odd" data-Schedule-id="-1">

In this case, I won't have any base reference. How can I search for that new row with dynamic random id ?

Thank You.

Answer 1

You can use below locators

For case-1

By.xpath("//tr[@id='Row00014']/following-sibling::tr[1]")

Or

By.cssSelector("tr#Row00014+tr[id*='Row']")

For case-2

By.cssSelector("table[class*='Schedule'] tr[id*='Row']");

Or

By.xpath("//table[contains(@class,'Schedule')]//tr[starts-with(@id,'Row')]")

Answer 2

From the HTML provided, the new row always has the class "new." With that info, you can use the code below.

WebElement newRow = driver.findElement(By.cssSelector("tr.new"));
// do something with newRow, e.g. newRow.click(), etc.
