Here’s how to handle dynamic XPaths with changing timestamps (e.g., id="dt_1_1741752232482"
) in Katalon:
Solution 1: Use a Dynamic XPath with starts-with
Modify the XPath to target the static portion of the ID (e.g., dt_1_
):
//*[starts-with(@id, 'dt_1_')]
Steps:
- In Katalon’s Object Repository, edit the element’s XPath to:
//*[starts-with(@id, 'dt_1_')]
- Use this object in your script:
WebUI.setText(testObject, "01/01/2024")
Solution 2: Use CSS Selectors (if applicable)
For IDs that start with dt_1_
, use a CSS selector:
[id^='dt_1_']
Set this as the element’s CSS Selector in the Object Repository.
Solution 3: Use Relative XPath with Other Attributes
If the element has other static attributes (e.g., name
, placeholder
, or class
), combine them with the dynamic ID:
//input[starts-with(@id, 'dt_1_') and @placeholder='Enter Date']
Solution 4: Use Regular Expressions (via matches()
)
If your XPath engine supports regex (limited in older browsers), use:
//*[matches(@id, 'dt_1_\d+')]
This matches dt_1_
followed by digits.
Solution 5: Dynamic XPath in Script (Programmatic Approach)
Construct the XPath dynamically in code:
String dynamicId = "dt_1_" + System.currentTimeMillis() // Example timestamp logic
WebElement element = DriverFactory.getWebDriver().findElement(By.xpath("//*[@id='${dynamicId}']"))
WebUI.setText(element, "01/01/2024")
Best Practices
- Add Explicit Waits to ensure the element is interactable:
WebUI.waitForElementPresent(testObject, 10)
- Verify Uniqueness: Ensure your dynamic XPath matches only one element.
- Test in Spy Web: Validate the XPath in Katalon’s Spy Web Utility before scripting.
By using starts-with
or CSS selectors, Katalon will reliably locate the element even with dynamic timestamps
