MarkLogic Server 11.0 Product Documentationtemporal:node-replace
temporal:node-replace( $temporal-collection as xs:string, $old as node(), $new as node(), [$temporal-doc-uri as xs:string] ) as empty-sequence()
Summary
Replaces a node in a temporal document.
| Parameters | |
|---|---|
| temporal-collection | The URI for the protected temporal collection in which the document is to belong. This must have been previously created by the temporal:collection-create function. All versions of the temporal document will be associated with this temporal collection. |
| old | The old node, to be replaced. |
| new | The new node. |
| temporal-doc-uri | The URI of the temporal document to be updated. |
Usage Notes
The forth argument "temporal-doc-uri" is not required for documents inserted with MarkLogic 9.0 version of temporal:document-insert or later.Attribute nodes cannot be replaced by non-attribute nodes. Non-attribute nodes cannot be replaced by attribute nodes. Element nodes cannot have document node children. Document nodes cannot have multiple roots.
If the caller of the function uses function mapping and $old
is an empty sequence, the node-replace function may return an
empty sequence. It will not return an error.

xquery version "1.0-ml";

let $options :=
<options xmlns="xdmp:document-insert">
<metadata>
<map:map xmlns:map="http://marklogic.com/xdmp/map">
<map:entry key="validStart">
<map:value>2014-04-03T11:00:00</map:value>
</map:entry>
<map:entry key="validEnd">
<map:value>2014-04-03T16:00:00</map:value>
</map:entry>
</map:map>
</metadata>
</options>
return
temporal:document-insert("kool","/example.xml",
<a><b>bbb</b></a>, $options);
(: add a c node before the b node :)
temporal:node-replace("kool", fn:doc("/example.xml")/a/b,
<c>ccc</c>);
(: look at the new document :)
fn:doc("/example.xml")
