ComfyUI Node: 段落提取或移除字符行(meeeyo.com)

段落提取或移除字符行(meeeyo.com):

The FilterLinesBySubstrings node is designed to process a block of text by filtering its lines based on the presence or absence of specified substrings. This node is particularly useful when you need to extract or exclude lines containing certain keywords or phrases from a larger text, allowing for more focused data analysis or content manipulation. By specifying substrings and choosing whether to retain or remove lines containing these substrings, you can efficiently manage and refine text data. This functionality is essential for tasks that require text cleaning, data preprocessing, or content curation, making it a valuable tool for AI artists who work with text-based data.

段落提取或移除字符行(meeeyo.com) Input Parameters:

input_text

The input_text parameter is a multiline string that represents the text you want to process. It serves as the source from which lines will be filtered based on the specified substrings. This parameter is crucial as it provides the raw data that the node will analyze and manipulate. There are no specific minimum or maximum values, but it is important to ensure that the text is formatted correctly with lines separated by newline characters.

substrings

The substrings parameter is a string containing one or more substrings separated by the pipe (|) character. These substrings are the criteria used to filter the lines in the input_text. The node will check each line to see if it contains any of these substrings. The default value is "查找符1|查找符2", which means you can specify multiple substrings to search for within the text. This parameter is essential for defining the filtering criteria and directly impacts which lines are retained or removed.

action

The action parameter determines whether lines containing the specified substrings should be retained or removed. It offers two options: "保留" (retain) and "移除" (remove), with "保留" being the default. This parameter is critical as it dictates the node's behavior in terms of filtering, allowing you to either focus on lines of interest or clean the text by removing unwanted lines.

段落提取或移除字符行(meeeyo.com) Output Parameters:

STRING

The output is a single string that contains the filtered lines from the input_text. The lines are joined together with newline characters, preserving the original order. This output is significant as it provides the refined text data after the filtering process, which can be used for further analysis or processing. The result reflects the action specified, either retaining or removing lines based on the presence of the substrings.

段落提取或移除字符行(meeeyo.com) Usage Tips:

• To effectively use this node, clearly define the substrings you are interested in by listing them in the substrings parameter, separated by the pipe (|) character.
• Use the action parameter to specify whether you want to keep or discard lines containing the substrings, depending on your data processing needs.
• Ensure that your input_text is properly formatted with lines separated by newline characters to avoid unexpected results.

段落提取或移除字符行(meeeyo.com) Common Errors and Solutions:

ValueError

• Explanation: This error may occur if the input parameters are not correctly formatted, such as providing an invalid string for the substrings or action parameters.
• Solution: Double-check the format of your input parameters. Ensure that substrings are separated by the pipe (|) character and that action is set to either "保留" or "移除".
