How to Unmarshal an XML document to a Map[string]string

[nvcnvn]

Is there any way read an XML document and but it to a
map[string]string? I have read about xml package but there only
example with struct.
For example:
#######################
<?xml version="1.0" encoding="UTF-8" ?>
<langs>
<en>English</en>
</langs>
#######################
or this file:
#######################
<?xml version="1.0" encoding="UTF-8" ?>
<langs>
<lang name="en">English</lang>
</langs>
#######################

I hope by some magical with xml pkg, I get a map: map["en"] ==
"English"

P/s: I can put it to a struct, after that loop over the struct range
and generate a map, but I need to find if there is one simple way!

XML doesn't really have a consistant way of mapping to map[string]string type. Who would decide the standard for how to deal with attributes, how would it know when you want a collection of something (implying slices) and when you just want single elements returned. In practice this is not that useful so you won't find anything like that in the standard library.

Most of the time when working with XML the structure is well defined, this is where Marshal/Unmarshal works really well, so if you know the scheme of your XML upfront; use the struct approach from xml.Marshal/Unmarshal.

If you don't know the structure you are parsing or you need something more specialist, you will need to use xml.Parser to step over the elements (Tokens) yourself.

Here's a really rough example of how to parse your first example into a map[string]string using xml.Parser to get you started:

Hello~ Why I code it hits: could not import xml (no required module provides package "xml")?

Note that you are replying to a discussion thread that is ten years old. It is better to start a new discussion thread in this type of situation. You also did not show us a minimal reproduction of your problem. Having said that, you would import that package by adding this to your program:

    import "encoding/xml"

See https://pkg.go.dev/encoding/xml.
