String patterns

You can use string patterns anywhere an expression function needs a name (such as a parameter or node name) to match multiple things at once.

*

Matches any string.

?

Matches any single character.

[chars]

Matches any of the characters between the square brackets. This does not support character ranges using a hyphen (you cannot do [a-z]).

^pattern

Removes strings matching pattern from the previous match.

@name

Matches attribute, object group, channel group, and/or bundle (depending on context).

Examples:

geo*

Matches everything beginning with "geo".

[gG]eo*

Matches everything beginning with "geo" or "Geo".

?eo*

Matches everything that has any character followed by "eo" and then any number of characters.

* ^geo1

Matches everything except the string "geo1".
