xPath 在使用 for-each 循環變量時找不到選擇器，但可以正常工作 (xPath not finding selector when using for-each loop variable, but works otherwise)

問題描述

xPath 在使用 for‑each 循環變量時找不到選擇器，但可以正常工作 (xPath not finding selector when using for‑each loop variable, but works otherwise)

塊包含以下內容，明確說明了值，它可以工作：</p>

ArrayList<String> fieldList = new ArrayList<String>();
fieldList.add("Street");
fieldList.add("City");
fieldList.add("Country");

我做錯了什麼？非常感謝。

方法 1:

You are forgetting to quote your strings in the XPath expression. Add single quotes around cField:

waitForElement.until(ExpectedConditions.elementToBeClickable(
                     By.xpath("//td[following‑sibling::td[2] = '" + cField + "']/input")));
   //                                     quotes added here ‑‑‑^  and here ‑‑‑^
WebElement checkBox =
   driver.findElement(By.xpath("//td[following‑sibling::td[2] = '" + cField + "']/input"));
   //                                      quotes added here ‑‑‑^  and here ‑‑‑^
