All,
I have simplified my example in the XQuery Console to:
let $string1 := "aaaa"
let $string2 := "bbbb"
let $length-1 := 1463
let $length-2 := 1464
let $string3 :=
fn:string-join
(for $a in 1 to $length-1
return 'x')
return fn:replace($string1,$string3,$string2)
Now using the length of 1463 it works fine. It is seen as a string a that is
what I want. But incremented the length by only 1 to 1464 (so replacing
$length-1 by $length-2 in the above example) I got the error:
XDMP-REGEX: (err:FORX0002) fn:replace("aaaa",
"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx...", "bbbb")
-- Invalid regular expression
But I just want that Marklogic also treats the the string of length 1464 as a
string and not as regular expression. So the question is:
Why does MarkLogic treat a second argument in fn:replace as a string when it
has length 1463 (or less) and why does it treat it as a regular expression when
it has length 1464 (or more)?
It is not about the usefulness of the above example. It is about why the error
appears. This example is just a simplifying of a situation which happens in a
production environment.
Regards,
Johan

second argument exceeds certain length
Hi,
Not sure about the details of the length (it's hard to look at a non-reduced
example containing a lot of noise), but you pass $piece-of-xml (or at least a
substring of it) as a regex to fn:replace().
So MarkLogic tells you it's not a valid regex, and it looks right to do so.
It's not clear what you want to replace in "aaaa" using the literal XML as a
regex.

This is just a simple query with the only goal to show the error.

let $test1 := fn:substring($piece-of-xml,1,$length-1)
return fn:replace($string1,$test1,$string2)
This returns the expected value 'aaaa'.
But when I increase the selected length by 1 by replacing:
let $test1 := fn:substring($piece-of-xml,1,$length-1)
by
let $test1 := fn:substring($piece-of-xml,1,$length-2)
I get the error:
XDMP-REGEX: (err:FORX0002) fn:replace("aaaa", "<change
when="2015-01-21" status="created"/>...", "bbbb") --
Invalid regular expression
The value of $test1 at that point is:
