Hello,
I need to change the prefix of an xml file root node like this

from
Code:
<?xml version="1.0" encoding="utf-8"?>
<HelloWorld xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://helloworld.test/v1">
.......
</HelloWorld>
to
Code:
<?xml version="1.0" encoding="utf-8"?>
<p:HelloWorld xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://helloworld.test/v1">
.......
</p:HelloWorld>
I can sucessfully load the original xml file into a cXMLDomDocument object, how can I simply add the prefix "p:" ?

Thank you very much
Luca
