Is it possible to merge a variable within single quotes in XPath?

Question

Is it possible to merge a variable within single quotes in XPath?

Currently working with nodeJS and experimenting with the following code snippet:

for (let i = 1; i <= elSize; i++) {
  try {
    let DeviceName = await driver
      .findElement(By.xpath("//span[@class='a-size-medium a-color-base a-text-normal']['i']"))
      .getText();
    console.log(i + ". Device Name: " + DeviceName + "\n");
  } catch (e) {
    await driver.executeScript(
      ...
      catch statements...
    );
  }
}

Attempting to include the 'i' variable from the for loop in the xpath. Facing issues due to the absence of double quotes, resulting in an unrecognizable xpath like this one:

driver.findElement(By.xpath("(//span[@class='a-size-medium a-color-base a-text-normal')["+ i +"]")).getText();

This causes the xpath to be unrecognized.

Here is an example of how the xpath can be identified in the browser:

//span[@class='a-size-medium a-color-base a-text-normal']['i']

To customize the XPath expression using the index value i, you can utilize the String.format method as shown in the following snippet:

var selector = "(//span[@class='a-size-medium a-color-base a-text-normal'])[{0}]"
for (let i = 1; i <= totalElements; i++) {
  var updatedSelector = String.format(selector, i);
  try {
    let ElementText = await driver.findElement(By.xpath(updatedSelector)).getText();
    console.log(i + ". Element Text: " + ElementText + "\n");
  } catch (e) {
    await driver.executeScript(
      ...
      appropriate catch block...
    );
  }
}

To avoid inefficiency, consider building a single XPath expression that includes a variable reference for i. This can be executed multiple times with different values of the parameter. For example:

//span[@class='a-size-medium a-color-base a-text-normal'][$i]

Another approach is to fetch all items at once using an XPath expression like:

//span[@class='a-size-medium a-color-base a-text-normal']

You can then iterate over the retrieved items in your host language (such as Javascript).
