sure; you need to mark your function as updating, and the db:output() function will allow you to return data. Your updated example is shown below. Hope this helps, Christian ___________________________________ module namespace page = 'http://basex.org/modules/web-page';
declare %updating
        %restxq:path("form/")
        %restxq:POST
        %restxq:form-param("content","{$form-input}", "'no message delivered'")
        function page:add-doc($form-input as xs:string) {

  let $new-doc:=
<root>
  <tag>
    <form-data>{ $form-input }</form-data>
   </tag>
</root>

  return (
    db:add("test_db", $new-doc, "test.xml"),
    db:output("database was updated.")
  )
};

Hi, Is it possible with restxq to add a document to a db? And if so, to also return an http response? I am trying to get the first part working with something along these lines:
declare %rest:path("form/")
        %rest:POST
        %rest:form-param("content","{$form-input}", "'no message
delivered'")
        function page:add-doc($form-input as xs:string) {

  let $new-doc:=
<root>
  <tag>
    <form-data>{ $form-input }</form-data>
   </tag>
</root>

  return db:add("test_db", $new-doc, "test.xml")
};
Many thanks, Colin

That's great - thanks! I was looking here for list of all annotations: http://docs.basex.org/wiki/RESTXQ But now I see these - %public, %private, or %updating - on this page too: http://docs.basex.org/wiki/XQuery_3.0#Annotations Are there any other annotations recognized by basex?

Hi Christian, I am getting this error with the below code [FOUP0001] Document expected, <root>...</root> found. Is this a problem with the way $new-doc is declared? Thanks, Colin module namespace page = 'http://basex.org/modules/web-page'; declare %updating %restxq:path("form/") %restxq:POST %restxq:form-param("content","{$form-input}", "'no message delivered'") function page:add-doc($form-input as xs:string) {
let $new-doc:=
    <root>
      <tag>
        <form-data>{ $form-input }</form-data>
       </tag>
    </root>

      return (
        db:add("test_db", $new-doc, "test.xml"),
        db:output("database was updated.")
      )
    };

You need to additionally wrap your constructed element into a document node:
  let $new-doc:= document {
<root>
  <tag>
    <form-data>{ $form-input }</form-data>
   </tag>
</root> }
Hope this helps, Christian
