如何从元帅重新排列XML标签

Question

The program I'm exporting XML for seems to want the xml tags to be in a specific order like the example below

<xml>
  <tagType1>data 1</tagType1>
  <tagType2>data 2</tagType2>
  <tagType1>data 3</tagType1>
  <tagType2>data 4</tagType2>
</xml>

In go, I marshal into a struct like below

type xml struct {
  TagType1 []string `xml:"tagType1"`
  TagType2 []string `xml:"tagType2"`
}

When I marshal that back out, it sorts the tags which is expected, but that is not what I need.

<xml>
  <tagType1>data 1</tagType1>
  <tagType1>data 3</tagType1>
  <tagType2>data 2</tagType2>
  <tagType2>data 4</tagType2>
</xml>

Is there a way with the encoding/xml package to reproduce the output in the first example? The order varies. I read an xml file with specific orders, modify the data and marshal that back out. I need the tag order to be kept.

You should be able to use something like this:

type xml struct {
   Item []ItemStruct `xml:",any"`
}

type ItemStruct struct {
  XMLName xml.Name
  Value string `xml:",chardata"`
}

That way you can keep the order, but you need to get the element name from each item by Item[i].XMLName
