gre - HTML

Introduction

gre-HTML is a powerful library for handling HTML documents in programming languages. It provides various functions, methods, and utilities to easily parse, manipulate, and generate HTML content.

Features

gre-HTML offers the following key features:

  • Parsing: It can parse HTML documents and provide a structured representation of the content.
  • Manipulation: It allows you to modify the HTML structure, add, remove, or modify elements, attributes, and text content.
  • Selectors: It supports powerful CSS selectors to easily locate specific elements within the HTML structure.
  • Rendering: It can render HTML documents into various output formats, such as PDF, images, or plain text.
  • Validation: It can validate HTML documents against defined standards or custom rules.
  • Generation: It allows you to generate HTML documents programmatically, making it easier to dynamically create content.
Installation

To use gre-HTML in your project, you need to follow these steps:

  1. Install the gre-HTML package using the package manager of your programming language. For example, in Python, you can use pip:
pip install gre-HTML
  1. Import the gre-HTML library in your code:
import gre-HTML
Examples
Parsing HTML

The following example demonstrates how to parse an HTML document using gre-HTML:

import gre-HTML

html = "<html><body><h1>Hello, gre-HTML!</h1></body></html>"
document = gre-HTML.parse(html)

# Access the parsed elements
h1_element = document.find_element("h1")
print(h1_element.text) # Output: Hello, gre-HTML!
Manipulating HTML

Once the HTML document is parsed, you can manipulate its structure using gre-HTML:

import gre-HTML

html = "<html><body><h1>Hello, gre-HTML!</h1></body></html>"
document = gre-HTML.parse(html)

# Update the text content of an element
h1_element = document.find_element("h1")
h1_element.text = "Greetings from gre-HTML!"

# Add a new element
p_element = gre-HTML.Element("p")
p_element.text = "This is a paragraph."
document.body.append(p_element)

# Convert the modified document back to HTML
modified_html = gre-HTML.to_html(document)
print(modified_html)

The above code will output the modified HTML document.

Rendering HTML

gre-HTML can render HTML documents into different output formats. Below is an example of rendering an HTML document into a PDF file:

import gre-HTML
import pdfkit

html = "<html><body><h1>Hello, gre-HTML!</h1></body></html>"

# Render HTML to PDF using gre-HTML and pdfkit
pdfkit.from_string(html, 'output.pdf')
Conclusion

gre-HTML provides a comprehensive set of tools for handling HTML documents in programming languages. Its features, such as parsing, manipulation, rendering, and generation, make it an essential library for web developers and programmers working with HTML content.
