解组包含混合内容的XML标签（例如CDATA，其他标签）

Try to unmarshal a xml file like:

<Element>
    <![CDATA[hello]]>
    <image>some_url_here</image>
    <![CDATA[world]]>
    mixed content here
</Element>

there are different types of data inside the Element tag, how can I unmashal this xml into a struct like:

type XMLElement struct {
    XMLName xml.Name `xml:"Element"`
    CDatas []string `....`
    Image string `...`
    PlainText string `...`
}

or any other struct this xml could be unmarshalled in.

This solution is not so good, because xmlquery mades CDATA element as TEXT node type, but I considered it is easy and simple, it using XPath query.

package main

import (
    "fmt"
    "strings"

    "github.com/antchfx/xmlquery"
)

func main() {
    s := `<?xml version="1.0" encoding="UTF-8"?><Element>
<![CDATA[hello]]>
<image>some_url_here</image>
<![CDATA[world]]>
</Element>
`
    doc, err := xmlquery.Parse(strings.NewReader(s))
    if err != nil {
        panic(err)
    }
    elem := xmlquery.FindOne(doc, "//Element")
    for n := elem.FirstChild; n != nil; n = n.NextSibling {
        if n.Data == "image" {
            fmt.Printf("image: %s
", n.InnerText())
        } else if n.Type == xmlquery.TextNode {
            if len(strings.TrimSpace(n.InnerText())) == 0 {
                // skip it because its' empty node
            } else {
                fmt.Printf("cdata: %s
", n.InnerText())
            }
        }
    }
    // or using query expression
    image := xmlquery.FindOne(doc, "//image")
    fmt.Printf("image: %s
", image.InnerText())
}
