如何在MarkLogic中更改元素的名称

Question

I want to do this change

From:

〈aaa〉 bbbbbb 〈/aaa〉

To:

〈bbb〉 bbbbbb 〈/bbb〉

by using MarkLogic, XQuery.

How to do that?

Answer 1

This can be done using xdmp:node-replace() Refer - xdmp:node-replace

HTH!

Answer 2

The simplest thing to do is often to use xdmp:node-replace . However, this assumes both that the data you wish to modify is already inside a document in the database and that you are not performing any conflicting updates to that document.

When it's not possible to use xdmp:node-replace, your next best option is to modify the document in-memory and then insert the entire document into the database.

The easiest way to modify the document in-memory is to use mem:replace from the XQuery Memory Operations library .

The most performant way to modify a document in memory is to write a recursive descent tree optimized to the structure of that document.

Answer 3

如果该节点不在文档中，则总是存在幼稚的方法：

〈aaa〉 bbbbbb 〈/aaa〉 ! <bbb>{.}</bbb>

Answer 4

XSLT也内置在服务器中。

Answer 5

xquery version "1.0-ml";
xdmp:document-insert("/test1.xml",
<root>
<child1>
<aaa>bbbbbb</aaa>
</child1>
</root>
);
doc("/test1.xml");
xdmp:node-replace(doc("/test1.xml")/root/child1/aaa,<bbb>bbbbbb</bbb>);
doc("/test1.xml");
