Re: [xml-dev] How many text nodes in this element with a CDATA section?

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() || """"
)
Cheers,

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")
