^exists( item | attribute)^ (DEPRECATED)

This pages describes features, codes or syntax whose use is now DEPRECATED, i.e. not advised either for new or continued pre-existing use.

Deprecated aspects of Tinderbox may be supported on a legacy basis but the latter support can't be presumed to be indefinite. Therefore you should update your active TBX documents to latest practice as soon as practical.

DEPRECATED - use $Attribute short form Boolean test.

^exists( object )^

If the item object exists for current note, this condition inside a in ^if(condition)^ block statement is true, where object is one of the {parent, child, childLinks, basicLinks, inboundLinks, lastChild, next, previous, nextSibling, and prevSibling} item objects.

^exists( attribute )^

This condition is true if the attribute (represented here by attribute) exists for the note, and if it is:

not zero, if the attribute is a number
not empty, if the attribute is a string
not black, if the attribute is a colour

…and it is always true if the attribute is a date.

But ^if(^exists(text))^ cannot be used to check if the note has some text content as text is not an attribute. Use ^if(text(this))^ instead.
