Question: help to convert xpath query to class chain

Hello

Is it possible to convert the following Xpath query to iOS class chain?

parentElement.findElement(
By.xpath("(.//XCUIElementTypeCell[.//XCUIElementTypeOther//XCUIElementTypeOther//XCUIElementTypeOther])[last()]"))

tks

For anyone landing here later: this one has no exact class chain, for two reasons.

  1. .//Other//Other//Other inside the predicate is a nested path. Class chain predicates can test a descendant ([$type == "XCUIElementTypeOther"$]), but not a path of several descendants.
  2. (...)[last()] is a position over all matches. WDA counts class chain matches breadth-first, XPath in document order, so [-1] can pick a different cell when the cells sit at different depths.

If the last cell is all you need, the closest chain is:

parentElement.findElement(AppiumBy.iOSClassChain("**/XCUIElementTypeCell[-1]"));

Check it on the screen. A stable accessibility id on the cell is the better fix.

I built an open-source XPath to iOS class chain converter that makes this call for you: it converts what has an exact chain, warns on approximations like [-1], and skips the rest with a reason. It runs over a whole test folder and prints a diff:

npx xpath-to-class-chain ./tests          # preview the diff
npx xpath-to-class-chain ./tests --write  # apply it
