For note, Meeseeks follows the same pattern for XPath queries:

iex(14)> doc = Meeseeks.parse(xmlString, :xml)
#Meeseeks.Document<{...}>

iex(15)> Meeseeks.all(doc, xpath("/A/B/text()"))
[#Meeseeks.Result<{ 23 }>, #Meeseeks.Result<{ 34 }>]

iex(16)> Meeseeks.all(doc, xpath("/A/B")) |> Enum.map(&Meeseeks.one(&1, xpath("text()")))
[#Meeseeks.Result<{ 23 }>, #Meeseeks.Result<{ 34 }>, nil]

iex(17)> Meeseeks.all(doc, xpath("/A/B")) |> Enum.map(&Meeseeks.text(&1))                
["23", "34", ""]

So I was able to find two methods of achieving the required result.

1. stream_tags(xmldoc, :B) |> Stream.map( fn {:B, doc} -> doc |> SweetXml.xpath(~x"./text()") end) |> Enum.to_list

2. xpath(xml, ~x"//A/B"l, number: ~x"text()") |> Enum.map(fn %{number: number} -> number end)
   Thanks everyone for your responses.

The following XPath expression will return the string representation of your B elements:

/A/B/string()

or

/A/B/number()

if you’re expecting a number (NaN will be returned in the “empty” ,B/> case). You can test it here: https://www.freeformatter.com/xpath-tester.html#

Haven’t tested with SweetXML though.
