How to get selectors with dynamic part inside using Selenium with Python?

Question

My application has a lot of selectors that have a dynamic ID inside. When that dynamic ID is at the end of the selector, I use [id^=\'staticPart\'] inside of ev

Answer 1

To identify an element with dynamic id e.g. #tab-t0-1 where 0 is a dynamic number and everything else is static you can use cssSelector with the following wildcards :

• ^ : To indicate an attribute value starts with

• $ : To indicate an attribute value ends with

So the most granular locator would include the strategy to lookout for the initial letters i.e. tab-t and the ending letters i.e. -1 and should be :

[id^='tab-t'][id$='-1']

Answer 2

You can, at the very least, combine both "starts with" and "ends with" selectors:

[id^='tab-'][id$='-1']

In general, though, depending on the selectivity of the id values like these, the [id$='-1'] part might not be significant or distinguishing and something more straightforward could be enough:

[id^=tab]

This is, of course, specific to the particular markup you are dealing with.
