Regex

What It Does

Performs regular expression search and replace operations on text. It finds patterns in your input string and replaces them according to your specified replacement pattern.

Inputs

Name	Description	Type	Required
input	The text to process	String	Yes
match	The regular expression pattern to find	String	No
flags	Regex flags (like "g" for global, "i" for case-insensitive)	String	No
replace	The replacement pattern	String	No

Outputs

Name	Description	Type
value	The text after pattern replacement	String

How to Use It

1. Drag the Regex node into your graph.

2. Connect the text you want to process to the "input" input. For e.g., color.red.100.

3. Set the "match" value to the regular expression pattern you want to find (without the slashes). For e.g., Color.

4. Set any "flags" you need for the regex operation (e.g., "i" to make it case insensitive).

5. Define the "replace" pattern to substitute for matched text (e.g., brand).

6. The output will be a string brand.red.100, where color is replaced with brand.

Tips

• Don't include the slash delimiters in your match pattern - just the pattern itself.

• Use the "g" flag to replace all occurrences rather than just the first match.

• Regex flags:

  • i : Ignore case, case-insensitive matching.

  • m : Multi-line, multi-line matching.

  • s : Dotall, dot matches any char including newline.

  • a : ASCII, ASCII-only matching.

  • x : Verbose, ignore whitespace and comments.

• You can combine these flags in any order. For example:

  • i - Case insensitive matching

  • im - Case insensitive and multiline matching

  • is - Case insensitive and dot matches newline

  • imsx - Multiple flags combined

Use Cases

• Text Cleanup: Remove or replace unwanted patterns or characters in text.

• Format Conversion: Transform text patterns from one format to another.

• Data Extraction: Isolate specific patterns from larger text blocks for token creation.
