soupvsnokogiri
soup is a Go library for parsing and querying HTML documents.
It provides a simple and intuitive interface for extracting information from HTML pages. It's inspired by popular Python web scraping
library BeautifulSoup and shares similar use API implementing functions like Find and FindAll.
soup can also use go's built-in http client to download HTML content.
Note that unlike beautifulsoup, soup does not support CSS selectors or XPath.
Nokogiri is a Ruby gem that provides a simple and powerful way to parse and search XML and HTML documents. It is built on top of the underlying C library libxml2, which is known for its speed and reliability.
Nokogiri provides a simple and intuitive API for parsing and searching XML and HTML documents, and it is widely used in the Ruby ecosystem for web scraping and data extraction.
One of the main features of Nokogiri is its ability to search and navigate through XML and HTML documents using a CSS or XPath selectors.
Nokogiri also provides a variety of other features that can simplify the process of working with XML and HTML documents. It can automatically handle character encodings and normalize documents, it can parse and search large documents with low memory usage, and it can validate documents against a DTD or schema.

Example Use
package main
import (
"fmt"
"log"
"github.com/anaskhan96/soup"
)
func main() {
url := "https://www.bing.com/search?q=weather+Toronto"
# soup has basic HTTP client though it's not recommended for scraping:
resp, err := soup.Get(url)
if err != nil {
log.Fatal(err)
}
# create soup object from HTML
doc := soup.HTMLParse(resp)
# html elements can be found using Find or FindStrict methods:
# in this case find <div> elements where "class" attribute matches some values:
grid := doc.FindStrict("div", "class", "b_antiTopBleed b_antiSideBleed b_antiBottomBleed")
# note: to find all elements FindAll() method can be used the same way
# elements can be further searched for descendents:
heading := grid.Find("div", "class", "wtr_titleCtrn").Find("div").Text()
conditions := grid.Find("div", "class", "wtr_condition")
primaryCondition := conditions.Find("div")
secondaryCondition := primaryCondition.FindNextElementSibling()
temp := primaryCondition.Find("div", "class", "wtr_condiTemp").Find("div").Text()
others := primaryCondition.Find("div", "class", "wtr_condiAttribs").FindAll("div")
caption := secondaryCondition.Find("div").Text()
fmt.Println("City Name : " + heading)
fmt.Println("Temperature : " + temp + "˚C")
for _, i := range others {
fmt.Println(i.Text())
}
fmt.Println(caption)
}
require 'nokogiri'
html_string = '<html><head><title>Page Title</title></head><body><h1 class="header-class">Hello World!</h1><p>This is a sample webpage.</p></body></html>'
# Parse the HTML string
doc = Nokogiri::HTML(html_string)
# Extract the class attribute of h1 tag using CSS selector
h1_class = doc.css("h1")[0]['class']
# or XPath
h1_class = doc.xpath("//h1")[0]['class']
puts "H1 class: #{h1_class}"
