RegEx Search
A regular expression, or RegEx, is a special text string for describing a search pattern. This makes them ideally suited for searching, text processing, and data validation. Using the RegEx search capabilities in selectors enables you to identify multiple target element with a single search execution. Without RegEx, multiple selectors would have been built to identify each target element.
In order to use the RegEx search capabilities, a matching option needs to be included in the tag of the element you want to identify, as follows:
|
Option |
Description |
|---|---|
|
|
Allows you to specify the target search tag, determined by the
<tag_name>
value.
|
|
|
Allows you to specify the search pattern through the
<regex_command>
expression used to identify the
<tag_name>.
|
Currently, the RegEx search is supported by the following selector types:
|

Tags which identify a process name. Example:
<html app="firefox.exe"> |
|
<name> tag alters between 0 and 2. Without the RegEx search, two selectors would have been built, one for each value of the <name> tag, as follows:
Selector for <name='Display is 0'> tag:
<wnd app='applicationframehost.exe' appid='Microsoft.WindowsCalculator_8wekyb3d8bbwe!App' title='Calculator' /> <uia cls='LandmarkTarget' /> <uia automationid='CalculatorResults' name='Display is 0' role='text' /><wnd app='applicationframehost.exe' appid='Microsoft.WindowsCalculator_8wekyb3d8bbwe!App' title='Calculator' /> <uia cls='LandmarkTarget' /> <uia automationid='CalculatorResults' name='Display is 0' role='text' />Selector for the <name='Display is 2'> tag:
<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 2' role='text' /><uia> tag makes it possible to generate a single selector to match both cases. A valid selector, in this case, looks something
like this:
Selector With RegEx Search
<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' /><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' attribute instructs our selector to use RegEx to identify the <name> tag, while the <name='Display is \d'> command returns all the numerical values for the <name> tag it identifies.
Below are a couple of more examples on how RegEx search works and what values it returns:
|
Regular Expression |
Description |
Returned Results |
|---|---|---|
|
|
Matches every string containing the RPA or Robotic Process Automation strings. |
|
|
|
Matches every string starting with the
Index value, followed by any number between 0 and 5.
