Text Processing Nodes

Text Processing nodes provide powerful string manipulation, formatting, and user interaction capabilities in ANDRON workflows.

Format Text Node

Transform and format text strings with various formatting options.

Configuration

• Input Text: Source text to format
• Format Type:
  • uppercase: Convert to uppercase
  • lowercase: Convert to lowercase
  • capitalize: Capitalize first letter
  • titleCase: Capitalize each word
  • trim: Remove leading/trailing whitespace
  • padStart: Left-pad string
  • padEnd: Right-pad string
  • truncate: Limit string length
  • template: Use template literals for complex formatting

Example

{
  "type": "formatText",
  "name": "Name Formatting",
  "input": "{{user.fullName}}",
  "formatType": "titleCase",
  "maxLength": 50
}

Use Cases

• Data normalization
• Display formatting
• Text sanitization
• Consistent text representation

Replace Text Node

Perform advanced text substitution and pattern matching.

Configuration

• Input Text: Source text
• Replace Mode:
  • simple: Direct text replacement
  • regex: Regular expression substitution
  • template: Dynamic replacement using template
• Search Pattern: Text or regex to find
• Replacement Text: Replacement strategy
• Case Sensitivity: Optional flag

Example

{
  "type": "replaceText",
  "name": "Email Anonymization",
  "input": "{{user.email}}",
  "mode": "regex",
  "pattern": "(\\w{3})\\w+(@\\w+\\.\\w+)",
  "replacement": "$1****$2",
  "caseSensitive": false
}

Use Cases

• Data masking
• URL transformation
• Sensitive information redaction
• Dynamic text generation

User Input Node

Capture and validate user-provided input with flexible configuration.

Configuration

• Input Type:
  • text: Free-form text
  • number: Numeric input
  • email: Email validation
  • date: Date input
  • boolean: Yes/No input
  • select: Predefined options
• Validation Rules:
  • required: Mandatory input
  • minLength: Minimum character count
  • maxLength: Maximum character count
  • pattern: Regex validation
  • enum: Allowed values
• Prompt: User-facing input description
• Default Value: Optional pre-filled value

Example

{
  "type": "userInput",
  "name": "Customer Feedback",
  "inputType": "text",
  "prompt": "Please provide your feedback:",
  "validation": {
    "required": true,
    "minLength": 10,
    "maxLength": 500
  },
  "errorMessage": "Feedback must be between 10-500 characters"
}

Use Cases

• Interactive workflows
• Dynamic data collection
• Form validation
• Survey and feedback systems

Error Handling

• Comprehensive input validation
• Detailed error messages
• Configurable error handling strategies
• Logging of text transformation steps
• Graceful failure modes

Performance Considerations

• Optimized string manipulation algorithms
• Minimal memory overhead
• Efficient regular expression processing
• Configurable complexity limits

Security Notes

• Input sanitization
• Prevent potential injection
• Escape special characters
• Configurable input constraints
• Protection against regex-based attacks

Advanced Features

• Dynamic template resolution
• Nested template interpolation
• Internationalization support
• Custom formatting plugins
• Context-aware text processing

Precision and Limitations

• Maximum input length: Configurable (default 10,000 characters)
• Unicode support for international text
• Complex regex with timeout protection
• Configurable error tolerance
• Support for most common text encodings
