## Usage
### Available Nodes
The plugin provides the following nodes:
- **Regex Match**: Performs regular expression matching operations
- **Regex Replace**: Performs regular expression replacement operations
### Node Parameters
#### Regex Match Node
- `text`: Input text to match
- `pattern`: Regular expression pattern
- `flags`: Regex flags (optional)
- Output: List of matched texts
#### Regex Replace Node
- `text`: Input text to process
- `pattern`: Regular expression pattern
- `replacement`: Replacement text
- `flags`: Regex flags (optional)

### Examples
1. **Extract Numbers**
```python
Input text: "Image size is 512x512"
Pattern: "\d+"
Output: ["512", "512"]

## Common Issues
1. **Regex Not Matching?**
- Check if the regex syntax is correct
- Verify if you need to use raw strings (r"pattern")
- Ensure special characters are properly escaped
