How to parse Netconf response and print certain values like a Python f-string to stdout

[bruckynetworkstest]

Apologies in advance if i am asking something daft or incorrectly.

I am just getting started with Scrapligo, so please be gentle.

I can run a successful get operation to provide the output for interfaces xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-interfaces-oper"/> on a Cisco ios-xe device and this gives me the standard long blurb of data.

1. Can I get this displayed on the terminal to look better (I would use xml.dom.minidom in Python)

2. Can i parse specific data out from here (like all interfaces in-unicast-pkts) and display this to ther terminal like i would in Python using an F-string ? rprint(f"Interface: [yellow]{int_name}[/yellow]'s in-unicast-pkts are {in-unicast-pkts}")

If any more detail is needed, please let me know.

Thanks.

package main, code I am working with below -

import (
	"fmt"

	"github.com/scrapli/scrapligo/driver/netconf"
	"github.com/scrapli/scrapligo/driver/options"
)

func main() {
	d, err := netconf.NewDriver(
		"x.x.x.x",
		options.WithAuthNoStrictKey(),
		options.WithAuthUsername("xxxxxx"),
		options.WithAuthPassword("xxxxx"),
		options.WithPort(830),
	)
	if err != nil {
		fmt.Printf("failed to create driver; error: %+v\n", err)

		return
	}

	err = d.Open()
	if err != nil {
		fmt.Printf("failed to open driver; error: %+v\n", err)

		return
	}

	defer d.Close()
	filter := `<interfaces xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-interfaces-oper"/>`
	r, err := d.Get(filter)
	if err != nil {
		fmt.Printf("failed executing GetConfig; error: %+v\n", err)

		return
	}
	if r.Failed != nil {
		fmt.Printf("response object indicates failure: %+v\n", r.Failed)

		return
	}

	fmt.Printf("Config result: %s", r.Result)
}

Typically as soon as you write the post, you can find the answer.

I can parse certain values and print them out now successfully.

Here is the script I am using for this.

package main

import (
	"fmt"
	"strings"

	"github.com/antchfx/xmlquery"
	"github.com/scrapli/scrapligo/driver/netconf"
	"github.com/scrapli/scrapligo/driver/options"
)

func main() {
	// Set the device IP address
	deviceIP := "x.x.x.x"

	d, err := netconf.NewDriver(
		deviceIP,
		options.WithAuthNoStrictKey(),
		options.WithAuthUsername("xxxx"),
		options.WithAuthPassword("xxxx"),
		options.WithPort(830),
	)
	if err != nil {
		fmt.Printf("failed to create driver; error: %+v\n", err)
		return
	}

	err = d.Open()
	if err != nil {
		fmt.Printf("failed to open driver; error: %+v\n", err)
		return
	}
	defer d.Close()

	filter := `<interfaces xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-interfaces-oper"/>`
	r, err := d.Get(filter)
	if err != nil {
		fmt.Printf("failed executing GetConfig; error: %+v\n", err)
		return
	}
	if r.Failed != nil {
		fmt.Printf("response object indicates failure: %+v\n", r.Failed)
		return
	}

	doc, _ := xmlquery.Parse(strings.NewReader(r.Result))

	interfaces := xmlquery.Find(doc, "//interfaces/interface")
	for _, iface := range interfaces {
		name := xmlquery.FindOne(iface, "./name").InnerText()
		inup := xmlquery.FindOne(iface, "./statistics/in-unicast-pkts").InnerText()
		outup := xmlquery.FindOne(iface, "./statistics/out-unicast-pkts").InnerText()

		fmt.Printf("Device %s has Interface %s: in-unicast-pkts=%s, out-unicast-pkts=%s\n", deviceIP, name, inup, outup)
	}
}
