Re: [basex-talk] Compare List Membership in XQuery
Just my guess ;) Thanks, Bridger. Here are some general comparisons
with their correct results:
() = () : false
() != () : false
(1,2) = (2,3) : true
(1,2) != (2,3) : true
(1) > (10,20,30,40,0) : true
(5) < (1,2,3,4) : false

Re: [basex-talk] Compare List Membership in XQuery
Chris -
thanks for sharing your solution (IMO it will help future searchers/readers
of the list, or others with similar problems searching the list archive)!
Note that the `!=` is an existential quantifier in XPath; i.e. it returns
`true` if *any* value on the left is not equal to *any* value of the
right*. So you might have had an expression problem earlier.

Bridger

Re: [basex-talk] Compare List Membership in XQuery
Hi Chris,
I’m glad to hear you found a solution.
I was surprised to hear that functx:is-value-in-sequence did the job,
though. The body of this function is nothing else than a general
comparison: $value = $seq [1] (and I would even have guessed that your
query will be eventually rewritten to a representation in which the
function body is completely inlined).
The query should be even faster if the import of the FunctX library
can be avoided. If the data is confidential, feel free to send us the
output of the Info View panel of the GUI.
Cheers,
Christian

Re: [basex-talk] Compare List Membership in XQuery
Hi Bridger,
The solution was indeed using is-value-in-sequence:
import module namespace functx = 'http://www.functx.com';
let $biblFull := distinct-values(collection('edil/Prologue Merged
2013.xml')//biblFull/@id)
let $biblStruct := distinct-values(collection('edil/Prologue Merged
2013.xml')//biblStruct/@id)
let $bibl := distinct-values(collection('edil/Prologue Merged
2013.xml')//bibl/@id)
for $title in collection('edil/eDIL-A.xml')//entry//title
where not(functx:is-value-in-sequence($title/@target, $biblFull))
and not(functx:is-value-in-sequence($title/@target, $biblStruct))
and not(functx:is-value-in-sequence($title/@target, $bibl))
return $title
It is also pretty speedy as well.
All the best,
Chris

Hi Everyone, I just tried using functx:is-value-in-sequence: where not(functx:is-value-in-sequence($title/@id, $biblFull)). I am still getting erroneous results.

Re: [basex-talk] Compare List Membership in XQuery
If you are allowed to share some snippets of the actual documents, it
will be easier to see how the query needs to be phrased.
Have you verified that $biblFull and $biblStruct actually contain
strings? If not, do you need to declare a default namespace? The
vocabulary looks like TEI, so
declare default element namespace "http://www.tei-c.org/ns/1.0;;
may be necessary. And if it is TEI, the ID attributes are probably
called @xml:id rather than @id.

Hi Gerrit,

Yes, they should be. If they are not, I need to find them so I can

Don’t you prepend a pound sign to @target attributes when they point to
IDs within the same document?
They are not in the same document. The @target attributes live spread
out in the other documents while the IDs all live in the same
document.
So you probably need to say
where not(substring($title/@target,2) = $biblStruct) and
not(substring($title/@target,2) = $biblFull)
I will give this a shot tomorrow when I am not as tired.
And maybe you need to restrict the titles that you search to those with a
@target attribute, like so:
for $title in collection('edil_target/eDIL-A.xml')//entry//title[@target]
This is the other half of the problem which I did not state here. I am
to find all titles that do not have target attributes then give them a
target attribute based on some rules. I have done so in a few files
(and I explicitly testing one of them in the query in my previous
email) and I will roll out the fix in all other files once I have
everything else tested and working.
I will give your suggestion a try tomorrow. Thanks!

Otherwise also non-@target-bearing titles will match the where clause,
which may be unintended.

try
for $title in collection('edil_target/eDIL-A.xml')//entry//title
where not($title/@target = $biblStruct) and not($title/@target = $biblFull)
return $title
Thank you for the quick reply at such a late hour! However, I am
getting the same results sadly. These results I can open the files
and find the targets that are being return in either of the two lists.
All the best,
Chris

Hello,
I have a question that is more XQuery based than BaseX specifically
but I thought I would pose it here to see if any one knows.
The basic problem statement is: given a list of tags that have an id
attribute and a list of target attributes which should correspond to
those ids, are there any target attrbutes which reference ids which do
not exist?
Basically, I am trying to link up a tag called biblFull or biblStruct
which have an id attribute with a tag named title which has a target
attribute which should match up with one of the two tags (biblFull or
biblStruct) above. I have formulated the query below which I believe
*should* give me all the title tags which do not exist either in the
biblFull or biblStruct id lists. I am not getting the results that I
am expecting.
let $biblFull := distinct-values(collection('edil_target/Prologue Merged
2013.xml')//biblFull/@id)
let $biblStruct := distinct-values(collection('edil_target/Prologue Merged
2013.xml')//biblStruct/@id)
for $title in collection('edil_target/eDIL-A.xml')//entry//title
where $title/@target != $biblStruct or $title/@target != $biblFull
return $title
I am basically getting all the title tags back which is not what I am
expecting at all. Can anyone shed any light on this?
Thank you very much in advance!
All the best,
Chris
