name The label contains numbers 0

<wnd app='applicationframehost.exe' appid='Microsoft.WindowsCalculator_8wekyb3d8bbwe!App' title='Calculator' />
<uia cls='LandmarkTarget' />
<uia automationid='CalculatorResults' name='Display is 0' role='text' />

name The label contains numbers 2

< wnd app='applicationframehost.exe' appid='Microsoft.WindowsCalculator_8wekyb3d8bbwe!App' title='Calculator' />
<uia cls='LandmarkTarget' />
<uia automationid='CalculatorResults' name='Display is 2' role='text' />

<wnd app='applicationframehost.exe' appid='Microsoft.WindowsCalculator_8wekyb3d8bbwe!App' title='Calculator' />
<uia cls='LandmarkTarget' />
<uia automationid='CalculatorResults' name='Display is \d' role='text' matching:name='regex' />

matching:name=‘regex’ Property instructs the picker to recognize using regular expressions label , and <name=‘Display is \d’> The command will return the recognized All values of the label .
