To parse web scraped content in Nim using CSS selectors we recommend the CSS3Selectors library which is designed with web scraping in mind:
import std/streams import pkg/chame/minidom import css3selectors let html = """ <!DOCTYPE html> <html> <head><title>Example</title></head> <body> <p>1</p> <p>2</p> <p>3</p> <p>4</p> </body> </html> """ let document = Node(parseHtml(newStringStream(html))) let elements = document.querySelectorAll("p:nth-child(odd)") echo elements # @[<p>1</p>, <p>3</p>] let htmlFragment = parseHTMLFragment("<h1 id='test'>Hello World</h1><h2>Test Test</h2>", Element()) let element = htmlFragment.querySelector("#test") echo element # <h1 id="test">Hello World</h1> CSS3Selectors was created to supersede nimquery which still works well for parsing HTML content in Nim if CSS3Selectors is not available:
from xmltree import `$` from htmlparser import parseHtml import nimquery let html = """ <!DOCTYPE html> <html> <head><title>Example</title></head> <body> <p>1</p> <p>2</p> <p>3</p> <p>4</p> </body> </html> """ let xml = parseHtml(html) let elements = xml.querySelectorAll("p:nth-child(odd)") echo elements # => @[<p>1</p>, <p>3</p>]
