Re: [MarkLogic Dev General] Why does fn:replace gives an error when second argument exceeds certain length

Hi John,
You are giving the wrong parameters in the second argument of fn: replace ,
replace work on patterns or the and you are passing second argument as
string,
So I think for the second argument in fn: replace you will have to provide
regex

I am using MarkLogic release 8.0-4 and I get a problem with fn:replace if

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:
