Message-ID: <CAP94bnOVJG87PtVo=-9oY2Y4bDxFBpNoYadY5+-Wi-dWdJdXMw@mail.gmail.com>

Dear all,

A new Summer Edition of BaseX is available! Our XML database system
and XQuery 3.1 processor provides the following new stunning features:

 DATABASE JOBS
 - all registered database jobs are now centrally administered
 - jobs can be scheduled (periodical execution, start/end time)
 - job results can be cached and retrieved later on
 - new Jobs Module: XQuery functions for managing jobs
 - new commands: JOBS [LIST|RESULT|STOP]
 - DBA: visualization of currently registered jobs

 XQUERY
 - parallel execution via xquery:fork-join (thank you, James Wright!)
 - alignments with the latest changes in the XQuery 3.1 specification
 - easy chaining of update operations with the 'update' keyword
 - numerous optimizations, smarter rewritings and heuristics

 XQUERY MODULES
 - File, Conversion, Fetch Module: handling of invalid XML characters
 - Inspection Module: inspect:function-annotations added

 OPTIONS
 - LOGPATH: custom path for logging data
 - CACHETIMEOUT: timeout for dropping cached job results
 - AUTHMETHOD: `custom` added to skip authentication

Visit http://basex.org to find the latest release, and check out
http://docs.basex.org/ to get more information. Have fun,

Christian
BaseX Team

Subject: [xquery-talk] How do I insert a node as first element within a for
	loop?
Message-ID: <CAFtPEJZb7qFBgMgOkFXu=CLqsE+McCXKgYgL+e_bhz+BNK=jqQ@mail.gmail.com>

Greetings,

Running in Basex I get the following error:

XUST0001 <https://www.w3.org/TR/xquery-update-10/#ERRXUST0001> element
constructor: no updating expression allowed.

When trying to insert *insert nodes test as first into $c*

I feel like my code is following the examples
<http://www.xmlmind.com/tutorials/XQueryUpdate/> I see online although
clearly I've got something wrong.

How do I insert a node with a for loop?

declare namespace db="http://basex.org/modules/db";
declare namespace file="http://expath.org/ns/file";
declare variable $form13FFileNumber as xs:string external;

let $data := db:open('13F')//data[contains(edgarSubmission/formData/coverPage/form13FFileNumber,$form13FFileNumber)]

let $fields :=

<form13FFile>
{
for $c in $data return
insert nodes <b4>test</b4> as first into $c
}
</form13FFile>

return file:write(concat('../OUT/' , $form13FFileNumber , '.xml'), $fields)

To be more clear my xml looks something like

   <data>
     <first_Child>text</first_child>
   </data>
   <data>
     <first_Child>text</first_child>
   </data>

and I would like it to adjust to

<form13FFile>
    <data>
     <b4>test</b4>
     <first_Child>text</first_child>
    </data>
    <data>
     <b4>test</b4>
     <first_Child>text</first_child>
    </data>
</form13FFile>

Hi Alex,

You can either use a query, or updates. Your query mixes both, which is why
you are getting an error, as updates can't be nested in expressions that
produce items.

In your case though, since you need to modify the top-level, a query makes
most sense, and the good news is it's really simple.

...
let $fields :=
<form13FFile>{
  $data
}</form13FFile>
...

Then you can replace the file with the results of the query as you do with
file:write.

If you really want to update, you can do something like:

replace node $data with
  <form13FFile>{
    $data
  }</form13FFile>

but then you can't use the file:write machinery and need to rely on the
underlying engine to do the edit in place.

In the more general case where you need to edit plenty of places in your
document, you can use the copy-modify-return expression. It's very handy to
create an updated copy.

I hope it helps!

Kind regards,
Ghislain

Hi Alex,

Me again. I read through your expected result too fast and missed the b4
part :-)

So indeed you need a copy modify:

...
let $fields :=
<form13FFile>
{
for $c in $data
return
  copy $new-node := $c
  modify insert nodes <b4>test</b4> as first into $new-node
  return $new-node
}
</form13FFile>
...

I hope I got it right this time!

Kind regards,
Ghislain
