Regex for matching when multiple words not preset in Visio

Hello Dojo,

I am trying to create a regex where when a user selects "Other" as a filter, it filters out all statuses that are not Online or Offline. The regex I have created is:  ^(?!(Online|Offline)).*

This regex works on Regex101.com, but does not work when applying it to the ClientSideRowFilter.

In my investigation, I found a regex we use to show all "Not Online" statuses as: !(online) and this regex works, though it does not look valid.

So I guess there are two questions:

  1. What is the best website to test regex for Visio?
  2. What would be the best regex to filter out all Online and Offline statuses using a ClientSideRowFilter?

Thank you in advance.

Hi Gabriel,

  1. Regex101 does not contain the .Net flavor (see their GitHub). You can use  http://regexstorm.net/tester though.
  2. I believe you're pretty close with the regular expression: ^(?!(Online|Offline)) should work.

    Note that your shape data should look something like this:
    ClientSideRowFilter:"Column name":Regex=^(?!(Online|Offline))

Hey Sebastiaan, so the first website still did not work with the !(online) regex and the regex you proposed did not work either. I did notice though that when I put in the filter “Status”:regex=!(Online|Offline) in the native Dataminer filter, it was filtered properly, but the moment I added that filter to the ClientSideRowFilter, it did not work

That’s because !(online) is probably not the regex you want it to be… The exclamation mark is a regular character unless it’s used in a different construction like (?!). The reason it probably fails in the shape data is because the pipe is a common separator for the Visual Overview.

So I just got it working, I had the separator change for the execute/regex replace, but not on the ClientSideRowFilter. But, the regex you provided did not work and the one that did work was !(Online|Offline)
I find it very weird because as you said, it should match on ! as a character and not as a condition.

That doesn’t seem right. I suggest this gets investigated as you might be relying on a software issue which might be fixed later on.
