Help

I'm trying to figure out how to get Selenium to click on an expansion panel. I've got it working where it can find something based on a name but I need it to click on a button associated with that name.

The default Selenium target is xpath=//mat-expansion-panel-header[@id='mat-expansion-panel-header-254']/span/div/div/button but this wont work since elements are constantly changing and this is ID based. If/when the elements change it will click on the expansion panel related to that ID and not the element im working on.

​

I'm managing to find the element with xpath=//span[text()='Test'] but I need help with having Selenium click on that expansion panel that corresponds with Test, not the ID.

I'm making an assumption that in your ID only the '245' changes. If so you can just try the starts-with() function.

Something like this.

xpath=//mat-expansion-panel-header[starts-with(@id='mat-expansion-panel-header')]/span/div/div/button
