Hi all,
I wnat to update an XML document in my xml database (Marklogic). I have xml as input and want to replace each node that exists in the target xml.
If a node does not exist it would be great if it gets added, but thats maybe another task.
My XML in the database:
<user>
<username>username</username>
<firstname>firstname</firstname>
<lastname>lastname</lastname>
<email>
[email protected]</email>
<comment>comment</comment>
</user>
The value of $user_xml:
<user>
<firstname>new firstname</firstname>
<lastname>new lastname</lastname>
</user>
My function so far:
declare function update-user (
$username as xs:string,
$user_xml as node()) as empty-sequence()
{
let $uri := user-uri($username)
return
for $node in $user_xml/user
return
xdmp:node-replace(fn:doc($uri)/user/fn:node-name($node), $node)
};
First of all I cannot iterate over $user_xml/user. If I try to iterate over $user_xml I get "arg1 is not of type node()" exception.
But maybe its the wrong approach anyway?
Does anybody maybe have sample code how to do this?
