I am trying to parse the following XML doc using SweetXML library.
<A>
<B>23</B>
<B>34</B>
<B></B>
</A>
However when I try to parse the document using: xpath(~x"/A/B/text()"l)
I get the response ['23', '34']. Is there anyway I can get the list with nil value for the element having no text ? The response that I expect is: ['23', '34', nil].

The proper W3C XPath 1.0 answer is NO. You select node-sets in XPath 1.0, then is not posible to select something that it doesn't exist.

I think you want to use optional mapping:
xpath(xml, ~x"//A/B"l, number: ~x"text()")
|> Enum.map(fn %number: number -> number end)
Output:
['23', '34', nil]
