PyQuery is a Python library for working with XML and HTML documents. It is similar to BeautifulSoup and is often used as a drop-in replacement for it.

PyQuery is inspired by javascript's jQuery and uses similar API allowing selecting of HTML nodes through CSS selectors. This makes it easy for developers who are already familiar with jQuery to use PyQuery in Python.

Unlike jQuery, PyQuery doesn't support XPath selectors and relies entirely on CSS selectors though offers similar HTML parsing features like selection of HTML elements, their attributes and text as well as html tree modification.

PyQuery also comes with a http client (through requests) so it can load and parse web URLs by itself.

xpath is a library for Go that allows you to use XPath expressions to select elements from an HTML document. It is built on top of the html package in the Go standard library, and provides a way to select elements from an HTML document using XPath expressions, which are more powerful and expressive than CSS selectors.

Example Use

```python from pyquery import PyQuery as pq # this is our HTML page: html = """ Hello World!

Product Title

paragraph 1

paragraph2

$10

""" doc = pq(html) # we can use CSS selectors: print(doc('#product .price').text()) "$10" # it's also possible to modify HTML tree in various ways: # insert text into selected element: print(doc('h1').append('discounted')) "

Product Titlediscounted

" # or remove elements doc('p').remove() print(doc('#product').html()) """

Product Titlediscounted

$10 """ # pyquery can also retrieve web documents using requests: doc = pq(url='http://httpbin.org/html', headers={"User-Agent": "webscraping.fyi"}) print(doc('h1').html()) ```

```go package main import ( "fmt" "github.com/antchfx/xpath" "golang.org/x/net/html" "strings" ) func main() { // Create an HTML string html := `

Hello, World!

Example

` // Parse the HTML string into a node tree doc, err := html.Parse(strings.NewReader(html)) if err != nil { fmt.Println("Error:", err) return } // Compile the XPath expression expr, err := xpath.Compile("//p") if err != nil { fmt.Println("Error:", err) return } // Use the Evaluate method to select elements from the document nodes, err := expr.Evaluate(xpath.NodeNavigator(doc)) if err != nil { fmt.Println("Error:", err) return } if nodes.MoveNext() { fmt.Println(nodes.Current().Value()) // > Hello, World! } } ```
