[basex-talk] BaseX 9.7 to BaseX 11: find a regex in an external file

[Josselin Morvan]

Hi Everyone, 

I'm migrating a webapp from BaseX 9.7 to BaseX 11 and I'm having a problem with 
a wrapper function (just a function for adding content to an xml template file)

Basically, this function looks for nodes in a template.xml file that matche 
regex to update the content of this file. Here is a small example : 

template.xml
<foo>
    <bar>{content}</bar>
</foo>

Query:
let $file := 'template.xml'
let $wrap := fn:doc($file)
let $regex := '\{(.+?)\}’ (: looking for something between curly braces :)

return
  for $node in $data//*
  where $node[fn:matches(text(), $regex)]
  return $node

This function worked with BaseX 9.7, but returns an error with BaseX 11 : 
[XPTY0004] Item expected, sequence found: ("&#xA; ", "&#xA;").

However, if I put the content of template.xml in a variable, it works (even 
with BaseX 11):
let $wrap :=
  <foo>
    <bar>{{content}}</bar> (: just escaped curly braces :)
  </foo>
let $regex := '\{(.+?)\}' 

return
  for $node in $wrap//*
  where $node[fn:matches(text(), $regex)]
  return $node
(:<bar>{content}</bar>:)

Do you have any idea of what I'm doing wrong or what I’m missing?

Thanks for your help!
Best,
