Re: [xsl] Subtle (or not?) Map Processing Bug in XQuery

["Eliot Kimber ekimber@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Good point about asbIbm OCD about it in XSLT but havenbt gotten there in
my XQuery yet.



But Ibm not sure how it would have caught the error in this case as in the
bug case Ibm still providing maps to map:merge(), just the wrong ones.



Cheers,



E.

Subject: Re: [xsl] Subtle (or not?) Map Processing Bug in XQuery





In my XQuery script Ibm building a map from all the image files in a
directory tree (using BaseXbs file extensions):



let $files := file:list($rootDir, true(), b*.pngb)

let $imageMap := map:merge(
for $file in $files

map:entry(local:getFilename($file), map{bpathb : $file, bkeynameb,
local:getKeyName($file))

)



At this point $imageMap is a map where each entrybs value is also a map.



Then declare it as such: don't forget the "as" clause. Declaring the types of
your variables would have caught the bug for you. It would also have made the
code more readable.
