XPath to select 1 element if one of two exists

Question

I want to select one element if one out of 2 exist while using this for 2 pages

1st page (price with discount)

<div class="price">
  <span class="originalRetailPrice">$2,990.00</span>
  </div>
</div>
<div class="price">
      <span class="salePrice">$1,794.00</span>
</div>

or 2nd page (only one price)

<div class="price">
  $298.00
</div>

I have used //span[@class="originalRetailPrice"] | (//div[@class="priceBlock"])[1] but I get the price twice

What I want is to select the first price when it's class="originalRetailPrice" or when it's //div[@class="price"]/text()[1]

So finally I want to make the selection to work on both pages

Answer 1

Use // to get texts at any level inside <div class="price">:

//div[@class="price"][1]//text()

Result:

Text=''
Text='$2,990.00'
Text=''

---

And filter the empty texts with: text()[normalize-space() and not(ancestor::a | ancestor::script | ancestor::style)]

//div[@class="price"][1]//text()[normalize-space() and not(ancestor::a | ancestor::script | ancestor::style)]

Result 1st page:

Text='$2,990.00'

Result 2nd page:

Text='$298.00'
