RegexMatchAll

Extracts all regex matches from text as an array of strings.

Syntax

RegexMatchAll(text, pattern)

Parameters

• text (string): The source text to search
• pattern (string): The regex pattern to match

Returns

• array: An array of all matching substrings, or an empty array if no matches are found

Description

Searches the input text for all occurrences of the specified regex pattern and returns them as an array of strings. Returns an empty array if no matches are found.

This function is designed for composability with array functions. The array return type allows direct chaining with functions like First(), Last(), Length(), Filter(), Join(), etc.

Examples

Extract all matches

var emails = RegexMatchAll("Contact john@example.com or jane@test.org", "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+")
# Returns ["john@example.com", "jane@test.org"]

Chaining with array functions

var emailCount = Length(RegexMatchAll(text, "[a-z]+@[a-z]+[.][a-z]+"))
# Count all email addresses

var firstEmail = First(RegexMatchAll(document, "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+"))
# Get the first email found

var allNumbers = Join(RegexMatchAll(data, "[0-9]+"), ", ")
# Join all numbers with commas

Extract all URLs

var urls = RegexMatchAll(htmlContent, "https?://[^ \"'<>]+")
# Returns array of all URLs found

Extract all words

var words = RegexMatchAll("Hello, World! How are you?", "[a-zA-Z]+")
# Returns ["Hello", "World", "How", "are", "you"]

No matches returns empty array

var result = RegexMatchAll("Hello World", "[0-9]+")
# Returns [] (empty array - no digits in text)

Notes

• Uses .NET regular expression syntax
• Throws a runtime exception if the regex pattern is invalid
• For a single match, use RegexMatch()
• For capture groups and match metadata, use RegexMatchDetail()

Pattern Escaping in Jyro Strings

Jyro strings support a subset of escape sequences (\n, \t, \r, \", \\). Common regex shortcuts like \d or \w require character class alternatives.

Use character classes instead:

Instead of	Use
\d	[0-9]
\w	[a-zA-Z0-9_]
\s	[ \t\n\r]
\.	[.]
