• Optional packages:

  • timeoutcall==1.*

Usage

Reading Page Titles

Firstly, if you would like to view page info alone, you could use a few functions for this:

import htmltagparse
title = htmltagparse.titleFromUri("https://github.com/")
print(title) # output: GitHub: Let’s build from here · GitHub

metadata = htmltagparse.metadataFromUri("https://github.com/") # meta tags from github

Building Pages

Building Pages via URI

from htmltagparse import build

brave = build.fromUri("https://search.brave.com/")
print(brave.response) #output: (200, 'OK')
print(brave.tags) #list of tags found on the specified page
print(brave.elapsed) #the time taken to create the html page class
print(brave.title) #title of the html page

This is not limited to these values alone; there are more values associated with an html page.

Building Pages via HTML

from htmltagparse import HtmlPage
from requests import get

htmlContent = get("https://duckduckgo.com/").text
ddg = HtmlPage(htmlContent)
print(list(ddg.sources)) #output: ['script']

Searching A Page

With this package, you have the ability to search the html page you have created directly through a function:

from htmltagparse import build
import re

videoId = ""
page = build.fromUri("https://www.youtube.com/watch?v=%s" % videoId)
try:
  #NOTE: the regex function already has re's MULTILINE and DOTALL flags in use
  #get a list of tags to the youtube video via this regex pattern
  videoTags = page.regex(r"\"keywords\":(?P<tags>\[.*?),\"channelId\":").group("tags")
  #converting from string to array
  videoTags = re.findall(r"(?:\"|\')(?P<tag>.*?)(?:\'|\")(?:\,|\])", videoTags)
except:
  videoTags = "no tags found"

print(videoTags)

Another way you could get tags from a Youtube video is with the find function, example:

import htmltagparse

videoId = "" #video id here
yt = htmltagparse.build.fromUri("https://www.youtube.com/watch?v=%s" % videoId)
elTagOpening = yt.find("meta", attrs={"name": "keywords"})[0]
videoKeywords = htmltagparse.getElementAttributeValue(elTagOpening, "content").split(", ")
print(videoKeywords) # tags of the youtube video
