Find String

Describe​

Find the specified content within the string and output the position of the found character (counting from 1). If not found, output 0.

Design principle​

Basic concept: a process can contain multiple components (process block, judgment, sub process, etc.), a process block can contain multiple commands, and a command can contain multiple attribute.

Prototype​

The command usually consists of "[process block variable]=[module name] [Command Name] (attribute 1, attribute 2,..) "format. Built in commands can default to the module name. The return value of the command is an optional design.

found_result = InStr(sText, sSubText, iPos, bCompare)

Attribute Description​

Output to​

For uniform output attribute, process block variables are usually used to receive the results after the command is executed. The output attribute is optional, which can be supported or not supported in command design, and can be received or not received in command use.

  • Found_result

Assign the result of the command execution to this variable.

Required Group​

In order to enter attribute, developers usually need to make modifications based on the default filling. When the number of attribute lists does not match, an error will be thrown when the command runs.

  • SText: string, default $PrevResult

    The string to be operated on - the string to be searched for

  • SSubText: string, default $PrevResult

    Find Content - What to Find in a String

  • IPos: number, default 1

    Start searching for location - the starting location for searching, where a position of 1 indicates starting from scratch

  • BCompare: boolean, default False

    Case sensitive - When searching for strings, is case sensitive

Command usage​

Visualization view​

Double click or drag the current command directly into the command list to switch to the default fill of each attribute visible in the attribute panel.

Source Code View​

Switch to the source code editor, and you can see the code results of each attribute that has been filled in by default. After modifying the source code, it can be automatically converted to visual results.

found_result = InStr($PrevResult, "", 1, False)

Note: When a required attribute is entered with an empty string and incomplete path, the developer usually needs to modify it according to the actual situation.
