Getting the base file name with a file with multiple periods: file.name.doc -> file.name Is there a function like "substring-before-last()" or can it be written in Workbench?example:file name: file.name.docsubstring-before(/process_data/@strInDocFileName, "."))returns: "file"need: "file.name"Would be great to have or write substring-before-last functionsubstring-before-last(/process_data/@strInDocFileName, "."))to get: "file.name"Is there a way to do it?Thanks
