How to handle dynamically changing id in dropdown and if I select class then it shows three matching nodes

Question

html snippet:

<div id="isc_PT" class="selectItemText" tabindex="5637" style="width:123px;height:12px;overflow:hidden;text-overflow:ellipsis;white-space:nowrap;" $9a="$9d" $89="isc_SelectItem_8" aria-expanded="false"></div>

If I select class I have 3 matching nodes. How can I handle that?

I have tried with

//div[contains(@id,'isc_PT')]

WebElement element=driver.findElement(By.xpath("//div[contains(@id,'isc_FX')]"));
            Select se=new Select(element);
            se.selectByVisibleText("MDialog");

Answer 1

     WebElement element=driver.findElement(By.xpath("(//div[@class='selectItemText'])[2]"));
                Thread.sleep(5000);
                element.click();
                Thread.sleep(10000);
driver.findElement(By.xpath("(//nobr[text( )='MDialog'])[4]")).click();  
//driver.findElement(By.xpath("//nobr[text()='MDialog']")).click();
                element.click();
                Thread.sleep(10000);
                driver.findElement(By.name("description")).sendKeys("MDialog");
                Thread.sleep(10000);

Answer 2

First of all Select is not working with Div or any other element.

Select are use only with element is having Select tag and inside it, only having option tags.

Solution :

WebElement element=driver.findElement(By.xpath("//div[contains(@id,'isc_FX')]"));
element.click();
driver.findElement(By.xpath("//*[text()='MDialog']")).click();

Try this.
