Algorithm (Workflow)

This function, strfindtag, is designed to extract a substring from a given text based on a search string and optional end conditions. It is part of the SolidGeometry library.

Input Parameters

• txt: The main text from which a substring is to be extracted.
• srch: The search string that marks the beginning of the desired substring.
• endstr: (Optional) A string that marks the end of the desired substring. If not provided, the function uses an empty string as default.
• endnl: (Optional) A boolean indicating whether a new line should be considered as an end condition. Defaults to false.

Output Results

• nam: The extracted and trimmed substring from the text.
• nxt: The remaining text after the extracted substring, also trimmed.

Algorithm Steps

1. Retrieve the endstr and endnl parameters using the getfuncparams function. If not provided, default values are used.
2. Use the strfindafter function to find the start and end indices (ss and ee) of the substring within txt that starts after srch and ends before endstr or a new line if endnl is true.
3. Extract the substring from txt using the indices ss and ee, and trim any leading or trailing whitespace to get nam.
4. Extract the remaining text after the end of the substring, starting from ee + 1 + numel(endstr) to the end of txt, and trim it to get nxt.

Example Usage

The function can be used to extract a product name from system information:

[~,b]=system('sw_vers')
strfindtag(b,'ProductName:',newline)

This example searches for the string 'ProductName:' in the output of the sw_vers command and extracts the product name, considering a new line as the end condition.
