如何动态更改xml节点？

Question

I am using golang to change the xml node dynamically? some struct is as the following:

type Row struct {
XMLName xml.Name `xml:"row"`
R string `xml:"r,attr,omitempty"`
}

after xml.Marshal(), it output maybe "<row r="123"></row>" but i want to change the "<row></row>" to "<myrow></myrow>" if some condition is true.

how to dynamically change the xml node using golang?

Here's a working example: Playground

xml.Name has a field Local that contains the name for the tag.

If you set the value of Local to "myrow" it will output the struct as <myrow r="..."></myrow>.

Also, you have to remove the xml tag from the XMLName field. When the xml packages sees this tag (xml:"row") it will automatically name the tag "row", no matter what XMLName contains.
