Question
I have a sitecore template field which I want to restrict to one or more or the following guids. They can appear in any order and will be pipe separated.
So far I have this regex, but this needs to FAIL if any other text other than the above guids and the separating pipes is entered.
[\|]?\{(7f05059e-4b4c-4d4d-bb39-1f57446719ef|57cb8e77-30cb-4dba-88bb-104cfea2e94f|c41ac6b6-a5c9-47f9-86c2-7db9e861e701|97133d89-36a1-4c28-9f30-4516eb469520)\}
How can I get this working as described?
I'm using sitecore, so I assume we are using .net regex here but it is difficult to tell :\
Solution
You need a little bit of modification to your expression to get it to work:

Russian^(?:\||(?:\{(?:7f05059e-4b4c-4d4d-bb39-1f57446719ef|57cb8e77-30cb-4dba-88bb-104cfea2e94f|c41ac6b6-a5c9-47f9-86c2-7db9e861e701|97133d89-36a1-4c28-9f30-4516eb469520)\}))*$
I have added the anchors ^ and $ to match the start-of-line and end-of-line respectively.
I have also added the * to entire grouping to support one or more of your GUIDs on the same line.
OTHER TIPS
Try ^ (line start) and $ (line end)
How about this:
^\{(7f05059e-4b4c-4d4d-bb39-1f57446719ef|57cb8e77-30cb-4dba-88bb-104cfea2e94f|c41ac6b6-a5c9-47f9-86c2-7db9e861e701|97133d89-36a1-4c28-9f30-4516eb469520)\}([\|]?\{(7f05059e-4b4c-4d4d-bb39-1f57446719ef|57cb8e77-30cb-4dba-88bb-104cfea2e94f|c41ac6b6-a5c9-47f9-86c2-7db9e861e701|97133d89-36a1-4c28-9f30-4516eb469520)\})*$
Here I have added ^ and $ to match the start and end of the string. Also, I have repeated the wanted strings for the first time and put the other one into a group. Then that group is repeated 0 to infinite times.
^\([\|]?\{(7f05059e-4b4c-4d4d-bb39-1f57446719ef|57cb8e77-30cb-4dba-88bb-104cfea2e94f|c41ac6b6-a5c9-47f9-86c2-7db9e861e701|97133d89-36a1-4c28-9f30-4516eb469520)\})+$
This is a shorter version, but allows an extra pipe in the beginning of the string.
