Just throw away this so-called "tool"  ; it is obviously buggy!

Try this in both BaseX and Oxygen and you will get correct results:

let $doc := parse-xml("<Test>
    <![CDATA[blah]]>
</Test>")
  return
   (
     $doc/Test/count(text()),
     """" || $doc/Test/text() ||  """"
   )

Hi Folks,

Consider this <Test> element which contains whitespace, a CDATA section, and then more whitespace:

<Test>
    <![CDATA[blah]]>
</Test>

What is the content of the <Test> element? Is it:

(a) A sequence of three strings: ("NL   ", "blah", "NL")

(b) A single string: "NL   blahNL"

I executed the following XPath expression to count the number of text nodes in the <Test> element:

        /Test/count(text())

that returned:

        1

Then I executed this XPath expression to show the text() node in the <Test> element:

        /Test/text()

that returned three items:

        "NL   "         /Test[1]/text()[1]
        "blah"                  /Test[1]/cdata-section()[1]
        "NL"            /Test[1]/text()[2]

Yikes!

The XPath results are contradicting each other, right?

I'm confused. What is the content of the <Test> element: a single string "NL   blahNL" or a sequence of three strings ("NL   ", "blah", "NL")
