Note that in some circumstances the splitregexp operator will include blank items in the list of results. For example,

[[the band thethe are the best the]splitregexp[the]]

The following results are returned:

["", " band ", "", " are ", " best ", ""]

Where it might be expected that the results would be:

[" band ", " are ", " best "]

The blank items mark the boundaries between matches. If they are not required they can be removed with the blank category of the is Operator: [[the band thethe are the best the]splitregexp[the]!is[blank]].

The reason that the blank items can be useful is that they allow search and replace operations to be constructed from a combination of the split Operator or splitregexp Operator and the join Operator. For example:

[[nobody, really; wants; to see -- all this \punctuation]splitregexp[,|;|-|\\]join[...]]

Syntax errors in the regular expression will cause the filter to return an error message. For example:

[[the cat sat on the mat]splitregexp[\]]
