What i understand is you are trying to read the value of ID attribute of an element. I am really not sure the intent of your question . But this how you can get to the value of ID.
You will need to get reference to the element using one of the various element locators. In this case, you have leveraged
By.xpath(). You can validate the correctness of theXPATHused by FirefoxXpathchecker. Once you use correctXPATH, you will get reference ofwebElement.WebElement wElement = driver.findElement(By.xpath("//ul//li[1]")); // validate the correct XPATH using available tools - ex : firefox xpath checker etc.You will need to get the value of
idattribute of the element.String requiredID = wElement.getAttribute("id");
Let me know if this works.

As pendem answered that, you can get first ID as you want by using xpath. But here I found that the xpath which you have used find 2 elements as there are two ul elements having li . If you use xpath having specific ul with class attribute as - .//ul[@ class="array collapsible"]//li[1] will work.

If you have provided all the relevant HTML, it should be as simple as the below.
String id = driver.findElement(By.cssSelector("span.num")).getText();
This just returns the first instance of the IDs.
If that doesn't work, you'll have to do some more digging, eg is this in an IFRAME or is it a timing issue or ?
