HTML Cleaning Script

This Node.js script is designed for processing and cleaning HTML content from a JSON Lines input file, extracting meaningful text, and writing it to a text output file. It leverages Node.js modules like fs, readline, cheerio, and stream for efficient processing.

Features

• HTML Cleaning: Extracts and cleans text from HTML content.
• Efficient Processing: Handles large files efficiently using streams.
• Customizable Input/Output: Allows specifying input and output file paths via command-line arguments.

Prerequisites

• Node.js installed on your machine.
• NPM for managing packages (if additional packages need to be installed).
• The cheerio package for HTML parsing (install with npm install cheerio).

Installation

Clone the repository or download the script to your local machine. Install the required Node.js packages:

npm install fs readline cheerio stream

Usage

Run the script with Node.js, optionally specifying the input and output file paths:

node script.js [inputFile] [outputFile]

• inputFile: Path to the input JSON Lines file containing HTML (default: 'cleaning.jsonl').
• outputFile: Path to the output text file (default: 'cleaned_data.txt').

Script Overview

• cleanHtml(html): Function to clean HTML content by removing unnecessary elements and normalizing text.
• CleaningTransform: A custom Transform stream class to process and clean HTML content.
• processFile(): Main function to set up streams and process the input file.

Customization

• Modify cleanHtml function for different HTML cleaning rules.
• Adjust stream buffer size in processFile for handling files of different sizes.

Troubleshooting

• Check for any errors in the console.
• Ensure input files are in the correct JSON Lines format.
• Validate the HTML structure in the input file for compatibility with the script.
