How to write \r and \Z in the same expression?

Question

For example, the following expression that looks for spaces at the beginning and end of a paragraph:
(^[[:blank:]]+)|([[:blank:]]+$)

I'm trying to add to this the case of end-of-article, end-of-table-cell spaces.
(^[[:blank:]]+)|([[:blank:]]+$)|([[:blank:]]+\Z)
The result failed.

But it's OK for you to separate two separate executions of ([[:blank:]]+\Z).

Allow them to be 2 separate GREP searches chained together in Find/ChangeByList script built into InDesign. Edit the FindChangeByList.txt textfile in the FindChangeSupport subfolder to write both searches. It already has a search to clean up trailing spaces. You could add a duplication that is adjusted to look at the beginning of the paragraph.

I made a version of this that does some 32 text cleanups and it is available on my website. If you want to use the built-in FindChangeByList, add this expression into the txt file:

grep {findWhat:"(?<=\\r)\\s"} {changeTo:""} {includeFootnotes:true, includeMasterPages:true, includeHiddenLayers:true, wholeWord:false}
//Find all spaces preceded by a return and remove the space.

grep {findWhat:"\\s(?=\\r)"} {changeTo:""} {includeFootnotes:true, includeMasterPages:true, includeHiddenLayers:true, wholeWord:false}
//Find all spaces followed by a return and remove the space.
