# WebDOM Extractor
**WebDOM Extractor** is an industrial-strength content extraction system that transforms complex web content into clean, structured data formats optimized for readability and information retrieval. Built on the [Postlight Parser](https://github.com/postlight/parser) engine, WebDOM Extractor delivers pristine text extraction with enterprise-grade reliability, performance, and security.
## Key Features
- **Pristine Content Extraction** - Strip away navigation, advertising, and other non-content elements
- **Multiple Output Formats** - Convert to JSON, Markdown, Plain Text, and HTML
- **Content Structure Preservation** - Maintain semantic structure during extraction
- **High-Volume Processing** - Process hundreds of URLs with asynchronous batch operations
- **Caching System** - Intelligent content caching to minimize redundant processing
- **Exhaustive Error Handling** - Comprehensive error recovery with detailed logging
- **Enterprise Security** - Sanitized output to prevent XSS and other injection attacks
- **Extensible Architecture** - Plugin system for custom content processors
- **Command Line Interface** - Powerful CLI with extensive configuration options
- **Advanced Configuration** - Fine-tune extraction parameters for your specific use cases
- **Comprehensive Testing** - 95%+ test coverage with unit and integration tests
## Installation
### Prerequisites
- Python 3.7+
- Node.js 12+
- Postlight Parser
```bash
# Install Node.js dependencies
npm install -g @postlight/parser
# Create virtual environment
python -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate
# Install Python package
pip install -e .
```
## Quick Start
```python
from webdom_extractor import Extractor
# Extract content from URL
extractor = Extractor()
document = extractor.extract_url("https://example.com/article")
# Get content in different formats
json_data = document.to_json()
markdown = document.to_markdown()
plain_text = document.to_text()
# Save to file
document.save("output.md", format="markdown")
```
## Command Line Usage
```bash
# Basic usage
webdom extract https://example.com/article
# Specify output format
webdom extract https://example.com/article --format markdown
# Output to file
webdom extract https://example.com/article --output article.md
# Batch processing from a file list
webdom batch url_list.txt --output-dir ./extracted_content
# With custom configuration
webdom extract https://example.com/article --config custom_config.json
```
## Advanced Configuration
WebDOM Extractor can be extensively configured to handle different extraction scenarios:
```json
{
"extraction": {
"preserve_images": true,
"extract_comments": false,
"ignore_links": true
},
"formatting": {
"line_width": 80,
"heading_style": "atx",
"wrap_blocks": true
},
"performance": {
"cache_enabled": true,
"cache_ttl": 86400,
"parallel_requests": 5
}
}
```
## Enterprise Use Cases
WebDOM Extractor excels in enterprise contexts:
- **Content Management Systems** - Clean import of external content
- **Knowledge Management** - Extract and index information from the web
- **Compliance & Archiving** - Save web content for regulatory requirements
- **Market Intelligence** - Collect and analyze competitor content
- **Data Mining & Analysis** - Extract structured data for analysis
- **Research Automation** - Collect and organize research content
## Architecture
WebDOM Extractor is built on a modular architecture:
