has_any_ipv4
Indicate whether a text contains any of several IPv4 addresses, matched as in `has_ipv4`.
The addresses are constant: string arguments, or one dynamic array of strings. Invalid addresses in the list are ignored, and an empty list gives false.
Syntax
has_any_ipv4(source, ip_addresses)Parameters
Prop
Type
Given a dynamic field
This parameter is string-only. In permissive mode — the default — almost every field arrives as a dynamic, so passing one works because Berserk injects asstring: extract-or-null, the value when it really is a string and null otherwise, so the call yields null (a predicate yields false). A property bag or array is therefore not matched, and tostring() is never applied implicitly — use it explicitly to match a bag's JSON text, keys included. Strict mode rejects the dynamic instead of coercing it. See String coercion and the asXXX family.
Returns: bool
Examples
Example 1 — Returns true; the first address appears
print has_any_ipv4('05:04:54 127.0.0.1 GET /favicon.ico 404', '127.0.0.1', '127.0.0.2')| print_0 (bool) |
|---|
| true |
Example 2 — The addresses as one dynamic array
print has_any_ipv4(
'05:04:54 127.0.0.1 GET /favicon.ico 404',
dynamic(['10.0.0.1', '127.0.0.1'])
)| print_0 (bool) |
|---|
| true |
