syntax
synopsisWHILE is the building block for repeated processing. The basic form is shown above."Conditional" is either a "compare" or "is defined" operation. A compare operator is a test of the value of a macro against a literal string. If the NOT tag is present in the WHILE markup, the evaluation of the conditional is reversed:
Just as with IF you can also check for a macro's existance:
If the condition is true, the block is evaluated and afterwards the WHILE tag is evaluated again. If the '$'-operator is used in the WHILE tag it is also reevaluated on each iteration. A loop block must be closed with the /WHILE tag.
