A Python package for simplified web scraping functionality for data scientists new to web scraping.

## Create Virtual Environment

We recommend that you first create a new `conda` environment with the latest version of Python (if not, then version 3.9 or higher). You can do so with the command below:

```bash
conda create --name webscraping python=3.12 -y
```

After the environment is created, activate the environment:

```bash
conda activate webscraping
```

## Installation

You can then install the package in your environment using the command:

```bash
pip install dsci524_group29_webscraping
```

After installation, have fun scraping the web!

## Functions

The package has three functions that you can use in a typical web scraping workflow as follows:

- `fetch_html(url)`: Retrieves the raw HTML content from the specified URL, handling HTTP requests and potential errors. You can capture the results in a `string` variable to use later in your pipeline.
- `parse_content(html, selector, selector_type)`: Parses the provided HTML content using CSS selectors or XPath to extract specified data. The `html` parameter is a `string` value retrieved using `fetch_html(url)`. This function returns a list of values that you can use in the final part of your pipeline.
- `save_data(data, format, destination)`: Saves the extracted data into the desired format (e.g., TXT, CSV, JSON) at the specified destination path.

## Usage

The examples below demonstrate how to use the main functions in this package. The examples fetch content from the [IANA Example Domain](https://example.com):

### 1. Fetch HTML Content
```python
from dsci524_group29_webscraping import fetch_html

# Fetch the raw HTML content from a webpage
url = "https://example.com"
html_content = fetch_html(url)
print(html_content)  # Outputs the HTML content of the page
```

### 2. Parse Content
```python
from dsci524_group29_webscraping import parse_content

# Parse the HTML content to extract specific elements
selector = "h1"  # Example: extract all <h1> header elements
selector_type = "css"  # Use CSS selectors
extracted_data = parse_content(html_content, selector, selector_type)
print(extracted_data)  # Outputs a list of the extracted data
```

### 3. Save Data
```python
from dsci524_group29_webscraping import save_data

# Save the extracted data to a CSV file
data = [{'value': 'Example Domain'}]  # Example data
file_path = save_data(data, format="csv", destination="output.csv")
print(f"Data saved to: {file_path}")
```

This package simplifies the process of fetching, parsing, and saving web data, making it ideal for beginners.
Usage is simplified by following the three simple steps above.

## Python Ecosystem

While libraries like [`BeautifulSoup`](https://www.crummy.com/software/BeautifulSoup/bs4/doc/) 
and [`Scrapy`](https://scrapy.org/) offer comprehensive web scraping capabilities,
*dsci524_group29_webscraping* aims to provide a more streamlined and beginner-friendly approach. 
By focusing on three core functions, it abstracts 
the complexities involved in web scraping, making 
it accessible for quick tasks and educational purposes.

**Similar Packages:**

- [`webscraping`](https://github.com/richardpenman/webscraping): Provides web scraping functions but contains a rich set of functionality that is beyond beginner level.
- [`webscraping_tools`](https://github.com/Jack-Tilley/webscraping_tools): Offers similar functionalities and many more that in our opinion, places it in the intermediate level.

*dsci524_group29_webscraping* differentiates itself by offering a simple set of functions 
that do the job for simple, beginner level needs.
