How to use regex expressions to select attachments - Cloud


This page demonstrates how to use the Attachment Table macro, which is part of the Advanced Tables for Confluence app, to select attachments based on the space or attachment name using a regex expression.

  • Use the special @self value for the Space key or space name regex parameter to match on all attachments in the current space.
  • Use .*png to match on attachments whose name ends in PNG.

Macro browser input

Select this macro

Macro nameAdvanced Tables - Attachment table
Macro syntax (Old editor){attachment-table}
Macro syntax (New editor - case insensitive)/Attachment Table

Define these parameters/values

Space key or space name regex @self
Attachment name regex.*png

Confluence is more limited on parameter values. Thus, | (pipe - used for regex or) is a reserved character and cannot be used.

Parameters set in the macro editor

Wiki markup input (Old editor)

Selecting attachments based on matching on more than one label

Constructing a regex to match attachments that have two or more specific labels is a bit more complicated. To do this, you must:

  1. Set the Label match option to all.
  2. Use a regex pattern similar to the following using xxx, yyy, and zzz as sample labels:
2 labels:  .*(?:.*\b(?:(?:xxx)|(?:yyy))\b.*){2}.*
3 labels:  .*(?:.*\b(?:(?:xxx)|(?:yyy)|(?:zzz))\b.*){3}.*
