Index XML with the Go bleve text indexing library

Question

How can I use the bleve text-indexing library, https://github.com/blevesearch/bleve, to index XML content?

I thought about using code like this XML parser in Go: https://github.com/dps/go-xml-parse, but then how do I pass what is parsed to Bleve to be indexed?

Update: My XML:

My XML looks like the following:

<page>
    <title>Title here</title>
    <image>image url here</title>
    <text>A sentence of two about the topic</title>
    <facts>
        <fact>Fact 1</fact>
        <fact>Fact 2</fact>
        <fact>Fact 3</fact>
    </facts>
</page>

You would create a struct defining the structure of your XML. You can then use the standard "encoding/xml" package to unmarshal XML into the struct. And from there you can index the struct with Bleve as normal.

package main

import (
    "encoding/xml"
    "fmt"
)

type Page []struct {
    Title string `xml:"title"`
    Image string `xml:"image"`
    Text  string `xml:"text"`
    Facts []struct {
        Fact string `xml:"fact"`
    } `xml:"facts"`
}

func main() {
    xmlData := []byte(`<page>
    <title>Title here</title>
    <image>image url here</image>
    <text>A sentence of two about the topic</text>
    <facts>
        <fact>Fact 1</fact>
        <fact>Fact 2</fact>
        <fact>Fact 3</fact>
    </facts>
</page>`)

    inputStruct := &Page{}
    err := xml.Unmarshal(xmlData, inputStruct)
    if nil != err {
        fmt.Println("Error unmarshalling from XML.", err)
        return
    }

    fmt.Printf("%+v\n", inputStruct)
}
