how to validate a element if it is returning any value or if it is empty… tried few ways but nothing is working, could you pls suggest

The error shows that one of the elements is null, and that means you can then not get any properties from it, be that a child element or a value.

You need to make sure each element exists before checking its value.

And please please, take a normal screenshot. Its so much harder to read ones taken with your phone and normal screenshots are easy.

Try this:

In UiPath, there are several methods to validate if an element returns a value or is empty, based on the element type (e.g., text fields, data tables). Here’s a summary of the approaches:

Method 1: Check UI Element’s Text

  1. Get Text Activity: Use this to retrieve text from a UI element and store it in a string variable (outputText).
  2. Validation: Use an If activity to check if outputText is empty using String.IsNullOrEmpty(outputText). Handle both the empty case and the case with a value.

Method 2: Check Data Table Values

  1. Read Range Activity: Read data from an Excel file or database into a DataTable variable (dataTable).
  2. Validation: Use an If activity to check if a specific cell is empty with the condition String.IsNullOrEmpty(dataTable.Rows(rowIndex)("ColumnName").ToString), replacing rowIndex and ColumnName as needed.

Method 3: Using Element Exists Activity

  1. Element Exists: Use this activity to determine if a UI element is present, storing the result in a boolean variable (elementExists).
  2. Condition Check: Check elementExists in an If activity to decide whether to proceed with retrieving text or handle the case where the element does not exist.

Additional Tips

  • Ensure accurate selectors to avoid unexpected results.
  • Use Delay or Wait Element Vanish for dynamic UIs to guarantee elements are fully loaded.
  • Incorporate Try-Catch blocks for robust error handling.

By utilizing these methods, you can effectively determine whether an element contains a value or is empty.

Hello, you can try to do something like XMLItems.Element.containsKey(“correspondenceAddress”) AndAlso (mandatory here, do not use simple And) XMLItems.Element(“correspondenceAddress”).Element.containsKey(“emailAddress”) AndAlso (mandatory here too) your condition
With this you check if each of y our dictionary contains the key you’re checking. Maybe the second condition is sufficient for your need depending if emailAdress can be on the keys if it’s non valorzed

Try using if condition like these and see
“ISNOTHING” or “ ” or “is null or empty” @devasaiprasad_K
