If the ContinueOnError property is true, no error is caught when the project is executed, even if a Catch node is used.

Inputs​

  • Unescape String - The input string containing HTML entities to convert.

Options​

This node does not have any options.

Output​

  • Unescaped - The string with HTML entities converted back to characters.

How It Works​

The Unescape HTML node converts HTML entities in a string back to their corresponding characters. When executed, the node:

  1. Retrieves the Unescape String input variable
  2. Validates that the string is not empty
  3. Uses the html.UnescapeString function to convert HTML entities:
    • < becomes <
    • > becomes >
    • & becomes &
    • " becomes "
    • ' becomes '
    • And other standard HTML entities
  4. Sets the unescaped string as the output variable

Requirements​

  • A non-empty string input containing HTML entities to unescape

Error Handling​

The node will return specific errors in the following cases:

  • Empty or invalid Unescape String input - "Unescape String can not be empty"

Usage Notes​

  • Useful for processing text that has been HTML-escaped and needs to be converted back to its original form
  • Commonly used after extracting text from HTML sources that may contain escaped characters
  • The reverse operation (converting characters to entities) can be performed with the Escape HTML node
  • Does not modify characters that are not HTML entities
  • Handles both named entities (like &) and numeric entities (like ')
  • The output string will be the same length or shorter than the input if entities were present
  • Works with standard HTML entities as defined in the HTML specification
  • Can handle multiple entities in a single string
  • Useful for cleaning up text extracted from web pages or HTML documents
