I’m automating Android apps using Selenium-Appium (Java) and I got some difficult to address the following need:
I have an element that doesn’t have any of ID or ACCESSIBILITY ID configured. But I’ve noticed that its value is a fixed pattern, a date, like “dd/MM/yyyy”.
So, I need “to get element in screen which pattern fits with ‘dd/MM/yyyy’ date pattern”. How am I supposed to achieve it?
I’d tried to call:
driver.findElement(MobileBy.xpath("//*[matches(@text,'" + regex + "')]"));
But only this error occurs:

Another useful information:
- Java version: 1.8
- Appium version: 7.5.1
My best regards and thank you for any help.

Answer
matches keyword can be used with xpath 2.0. I was not able to find online which version does the appium client app use, but you can implement an intermediary solution with java core:
First find all the elements that contain slash
List<WebElement> slashElements = androidDriver.findElementsByXPath("//*[contains(@text,'/')]");
Then apply the regex (here maybe find a regex standard for date or experiment with different patterns like (0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)dd)
WebElement dateElement = slashElements.stream().filter(webElement -> Pattern.compile("\d{1,2}/\d{1,2}/\d{4}").matcher(webElement.getText()).matches()).findFirst().get();
Also just learned how to implement a simple Appium automation framework using Server GUI, Inspector, Selenium, Intellij and Android Studio, so thank you.
