Looping through a Table with separate colums and clicking on an item within it

I would like to loop through a list of div classes that is dynamically generated in two columns (fixed), rows (dynamically generated). I would like to select a button on the second column with a group of buttons with same name tag.

So far I could not work out how to grab all the row items in a list <Webelement> given the css selector and finding by tagname

The pseudocode I have in mind is:

• Initialise 2D array for rows and columns
• Get all items in first column by name
• Get all items in second column by id
• while looping through the rows in both columns
• Locate the item in last row for both columns by name and id
• When name matches to string “1234”
• click the button in the second column same row.
• Assert statement that action has completed successfully
• Or Assert statement that item could not be found
• Terminate browser
• End program

I have this html as a sample to code against:

<div id="bookings">
  <div class="row">
    <div id="25203" class="row">
      <div class="col-md-2">
        <p>Jola</p>
      </div>
      <div class="col-md-2">
        <p>Hunters</p>
      </div>
      <div class="col-md-1">
       <p>105</p>
      </div>
      <div class="col-md-2">
        <p>true</p>
      </div>
      <div class="col-md-2">
        <p>2017-02-25</p>
      </div>
      <div class="col-md-2">
        <p>2017-03-02</p>
      </div>
      <div class="col-md-1">
        <input onclick="deleteBooking(25203)" value="Delete" type="button"/>
      </div>
    </div>
    <div id="25204" class="row"> //I would like to grab items from this list
      <div class="col-md-2">
        <p>Jola</p>
      </div>
      <div class="col-md-2">
        <p>Hunters</p>
      </div>
      <div class="col-md-1">
        <p>105</p>
      </div>
      <div class="col-md-2">
        <p>true</p>
      </div>
      <div class="col-md-2">
        <p>2017-02-25</p>
      </div>
      <div class="col-md-2">
        <p>2017-03-02</p>
      </div>
      <div class="col-md-1">
        <input onclick="deleteBooking(25204)" value="Delete" type="button"/> //I would like to click on this button.
      </div>
    </div>

Any advise on how to use Selenium-webdriver with Java (using Eclipse and Cucumber plugin).

UPDATE: My first attempt to code gives me this:

//Scenario 2: Verify on clicking the delete button for an existing customer
    @Given("^I am on the Hotel booking form with saved customers$")
    public void I_am_on_the_Hotel_booking_form_with_saved_customers() throws Throwable {
    //Validate if customers records exist in the table.     

        List<WebElement> rows = driver.findElements(By.xpath(".//*[@id='bookings']//div[@id]"));
        java.util.Iterator<WebElement> i = rows.iterator();
        while(i.hasNext()) {
            WebElement row = i.next();
            System.out.println(row.getText());              
        }           
    }

    @When("^valid customers data is being displayed$")
    public void valid_customers_data_is_being_displayed() throws Throwable {
        // Write code here that finds and lists all the rows in a table
        WebElement dynamicDivs = driver.findElement(By.xpath(".//*[@id='bookings']"));
        List<WebElement> rows = dynamicDivs.findElements(By.tagName("p"));
        java.util.Iterator<WebElement> i = rows.iterator();
        while(i.hasNext()) {
            WebElement row = i.next();
            System.out.println(row.getText());
        }           
    }

    @When("^I click the delete button$")
    public void i_click_the_delete_button() throws Throwable {
        // Write code to delete a specific customer in a row given the firstname = "Tim" and price = "999.99"
        WebElement pricenumber = driver.findElement(By.className("col-md-1"));
        //List<WebElement> rows1 = classnames.findElements(By.tagName("p"));

        java.util.Iterator<WebElement> i = rows1.iterator();
        while(i.hasNext()) {
            WebElement row1 = i.next();
            System.out.println(row1.getText());
            string firstnames = driver.findElement(By.className("col-md-2"));
            System.out.println(firstnames.getText());

            if (row1.getText() == "999.99" && firstnames == "Tim" )
            {
                driver.findElement(By.className("col-md-1").cssSelector(".col-md-1>input")).click();

            }
            //Assert that row has been deleted.
        }          
    }

    @Then("^I should see the customer details on the last row been deleted$")
    public void i_should_see_the_customer_details_on_the_last_row_been_deleted() throws Throwable {
         // Write code here to search for firstname if it does not exist
        WebElement dynamicDivs = driver.findElement(By.xpath(".//*[@id='bookings']"));
        List<WebElement> rows = dynamicDivs.findElements(By.tagName("p"));
        java.util.Iterator<WebElement> i = rows.iterator();
        while(i.hasNext()) {
            WebElement row = i.next();
            System.out.println(row.getText());
            if (row.getText() != "Tim")
            {
                Assert.assertFalse(row.getText(), "Tim");                   
            }
        }
        driver.close();
        driver.quit();
    }       

Note that the id tag is randomly generated, which means I’ll have to loop through and select the last id from the group. eg:

<div id="25217" class="row">
    <div class="col-md-2">
    <p>Tim</p>  

webdriver.findElements(By.XPath("//div[@id='bookings']/div));

webdriver.findElements(By.XPath("//div[@id='25204']/div));
