ComfyUI Node: LogicUtil_AContainsB(String)

LogicUtil_AContainsB(String):

The LogicUtil_LogicGateCompareString node is designed to determine if a specified regular expression (regex) pattern is found within a given string. This node is particularly useful for tasks that require pattern matching or text validation, such as checking if a string contains a specific sequence of characters or validating input formats. By leveraging the power of regular expressions, this node provides a flexible and powerful way to perform complex string comparisons, making it an essential tool for AI artists who need to automate text-based logic in their workflows.

LogicUtil_AContainsB(String) Input Parameters:

regex

This parameter represents the regular expression pattern that you want to search for within the input string. Regular expressions are a powerful tool for matching patterns in text, allowing you to specify complex search criteria. The default value is an empty string (""), which means no pattern is specified. You can customize this parameter to match any pattern you need, such as specific words, sequences of characters, or more complex patterns.

input2

This parameter is the string in which the node will search for the specified regex pattern. The default value is an empty string (""). This input string is the text that will be analyzed to determine if it contains the pattern defined by the regex parameter. You can provide any string value here, and the node will return whether the pattern is found within this string.

LogicUtil_AContainsB(String) Output Parameters:

BOOL

The output of this node is a boolean value (True or False). It indicates whether the specified regex pattern was found within the input string. If the pattern is found, the output will be True; otherwise, it will be False. This boolean output can be used in subsequent nodes to control the flow of logic based on the presence or absence of the pattern in the input string.

LogicUtil_AContainsB(String) Usage Tips:

• Use this node to validate user inputs by checking if they match a specific format, such as email addresses or phone numbers.
• Combine this node with other logic nodes to create complex conditional workflows based on text patterns.
• Experiment with different regex patterns to match various text criteria, enhancing the flexibility and power of your AI-driven projects.

LogicUtil_AContainsB(String) Common Errors and Solutions:

Invalid regular expression

• Explanation: The regex pattern provided is not valid and cannot be processed.
• Solution: Ensure that the regex pattern is correctly formatted and adheres to the syntax rules of regular expressions.

Empty input string

• Explanation: The input string (input2) is empty, so no pattern matching can be performed.
• Solution: Provide a non-empty string for the input2 parameter to enable pattern matching.

Pattern not found

• Explanation: The specified regex pattern is not found within the input string.
• Solution: Verify that the input string contains the pattern you are searching for, or adjust the regex pattern to match the desired text.
