| Parameter

Description

Default
|
| hide |
Suppress any output text that would ordinarily be returned from this tag.
(This universal parameter was introduced with Interchange version 5.5.2.) |
No
|
| reparse |
Process any Interchange tags found in the text output from this tag. |
No
|
Description
The [either] tag implements a check for the first true
(non-blank, non-zero) value.
It splits on "[or]" and then, with each block found,
it interpolates any ICML tags
that are present and then strips any leading or trailing whitespace from
the resulting value.
The first interpolated and stripped block
found to have a true value (in the Perl sense) will be returned.
After a true value is found, any subsequent "[or]" blocks
will be discarded without any further processing.
If none of the blocks are found to have a true value,
then the interpolated
and stripped value of the last block will be returned.
|
Behaviour change
Prior to Interchange 5.0.0,
if all of the split blocks were found to be false then
this tag would return nothing at all.
In Interchange 5.0.0 and later,
if all of the split blocks are found to be false then
the return value will be the content of the last block
(minus any leading and trailing whitespace).
