ComfyUI Node: Text Find

Text Find:

The Text Find node is designed to help you locate specific substrings or patterns within a given text. This node is particularly useful for tasks that require text analysis or manipulation, such as searching for keywords, validating text formats, or extracting specific information from larger text bodies. By providing either a substring or a regular expression pattern, the node can efficiently determine if the specified text is present, making it a versatile tool for various text processing needs.

Text Find Input Parameters:

text

This parameter represents the main body of text in which you want to search for a substring or pattern. It is a required input and must be of type STRING. The text can be any length and contain any characters, providing the context for the search operation.

substring

This parameter allows you to specify a specific sequence of characters to search for within the main text. It is of type STRING and is optional. If provided, the node will check if this exact substring exists within the text. The default value is an empty string, and it does not support multiline input.

pattern

This parameter enables you to define a regular expression pattern to search for within the main text. It is of type STRING and is optional. If provided, the node will use this pattern to perform a more complex search, allowing for advanced text matching capabilities. The default value is an empty string, and it does not support multiline input.

Text Find Output Parameters:

found

This output parameter is of type BOOLEAN and indicates whether the specified substring or pattern was found within the main text. If the substring or pattern is present, the output will be True; otherwise, it will be False. This result helps you quickly determine the presence of the desired text within the larger body.

Text Find Usage Tips:

• To search for a simple word or phrase, use the substring parameter for a straightforward and efficient search.
• For more complex searches, such as finding text that matches a specific format or pattern, use the pattern parameter with a regular expression.
• Ensure that the text parameter is correctly populated with the text you want to search within, as this is the primary context for the search operation.

Text Find Common Errors and Solutions:

Invalid regular expression pattern

• Explanation: The pattern parameter contains an invalid regular expression.
• Solution: Verify that the regular expression syntax is correct and conforms to the expected format.

Missing text input

• Explanation: The text parameter is empty or not provided.
• Solution: Ensure that the text parameter is populated with the text you want to search within.

Both substring and pattern provided

• Explanation: Both substring and pattern parameters are provided, causing ambiguity in the search operation.
• Solution: Provide only one of the substring or pattern parameters to avoid confusion and ensure the node performs the intended search.
