Chopper is a tool to extract elements from HTML by preserving ancestors and CSS rules.

Compared to other HTML parsers Chopper is designed to retain original HTML tree but eliminate elements that do not match parsing rules. Meaning, we can parse HTML elements and keep thei structure for machine learning or other tasks where data structure is needed as well as the data value.

htmlquery is a Go library that allows you to parse and extract data from HTML documents using XPath expressions. It provides a simple and intuitive API for traversing and querying the HTML tree structure, and it is built on top of the popular Goquery library.

Example Use

```python HTML = """ Test
HELLO WORLD Do not want 


<div id="footer"></div>

"""

CSS = """ div { border: 1px solid black; } div#main { color: blue; } div.iwantthis { background-color: red; } a { color: green; } div#footer { border-top: 2px solid red; } """

extractor = Extractor.keep('//div[@class="iwantthis"]').discard('//a') html, css = extractor.extract(HTML, CSS)

will result in:

html """

HELLO WORLD

"""

css """ div{border:1px solid black;} div#main{color:blue;} div.iwantthis{background-color:red;} """ ```

```go package main

import ( "fmt" "log"

"github.com/antchfx/htmlquery" )

func main() { // Parse the HTML string doc, err := htmlquery.Parse([]byte(<html> <body> <h1>Hello, World!</h1> <ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> </ul> </body> </html>)) if err != nil { log.Fatal(err) }

// Extract the text of the first

element h1 := htmlquery.FindOne(doc, "//h1") fmt.Println(htmlquery.InnerText(h1)) // "Hello, World!"

// Extract the text of all

  • elements lis := htmlquery.Find(doc, "//li") for _, li := range lis { fmt.Println(htmlquery.InnerText(li)) } // "Item 1" // "Item 2" // "Item 3" } ```
