A little help with Search and place using RegEx

Attempting to match for something like this:


However, I just want it to replace the ":[0-9]{10}" portion. If I just search for ":[0-9]{10}" it will replace instances where "[a-z]{3,6}:[0-9]{10}" would not apply. Any help would be greatly appreciated!

Just turn the bit you want to replace into a capture group using parentheses like this:


and then just replace the captured group. Would that work?

It would be best for you to post, in a Code Block, a real-world example of the source text you want to match, and then an example of what the results would look like, in addition to your objective.
