Thanks for the reply,

I tried using the function fn:parse-xml, I had success with using it in BaseX GUI like this:

let $message := fn:parse-xml('<Id>CTN55</Id>') return insert nodes $message as last into doc("calastone/calastone.xml")

But when I tried to do the same with POST API method from my application with using this xquery:

string xquery = "<query><text>let $message:= fn:parse-xml('<Id>CTN58</Id>')" + "return insert nodes $message as last into doc("calastone/calastone.xml")</text>" + "<variable name = 'message' value = fn:parse-xml('<Id>CTN58</Id>'))/></query>";

I get the error: "" (Line 1): Element type "variable" must be followed by either attribute specifications, ">" or "/>"

Can you help on how to do this insertion?

Thanks.

If you pass some XML in to your query as text (because that is the only thing you can have inside an attribute) you have to do a parse-xml (or parse-xml-fragment if its more like a sequence) and insert that.

I'm Using POST method to update BaseX database, I want to insert an xml node to an existing document calastone.xml in calastone database , if the node contains '<', it returns an error " Line 6): The value of attribute "value" associated with an element type "variable" must not contain the '<' character." code: <query> <text> let $message := '<Id>CTN53</Id>' return insert nodes $message as last into doc("calastone/calastone.xml") </text> <variable name='message' value='<Id>CTN53</ID>'/> </query> the same code without '<' adds the text correctly. how to solve this problem? Note that this is a question I posted on Stackoverflow, Linkhttps://stackoverflow.com/questions/60456387/passing-in-xquery-with-basex-post-method/60456826?noredirect=1#comment106958333_60456826. Christian Grun suggested using &lt; and &gt; for attributes and CDATA for text nodes. After applying that solution, the xml stored is in this form &lt;Id&gt;CTN53&lt;/Id&gt; This is not what I'm looking for. Is there any other more convenient solutions to store XML messages with Rest APIs? I know PUT method works fine but it overwrites the content of the document. Thank you.
