Getting single element with similar xpaths but with different same level, "neighboring" node

Question

I'm trying to get the xpath of an element with a similar xpath to others but has a "neighbor" element that's different . Please see example below.

<div>
   <div id='a'> </div>
   <span> Text here </span>  #this is what i'm trying to get
</div>
<div>
   <div id='b'> </div>
   <span> Text here </span>
</div>

I tried using //div//span, but this gives me the 2 spans. So i tried using //div//child::div[@id='a']//ancestor::div//child::span, but it doesn't look pleasant and looks repetitive. Does this have a better implementation?

Answer 1

try

//div[div[@id='a']]/span

it says get the span child node of all div nodes with child node div (with an @id equal to 'a').
