Hello all.

i have a problem i can't parse a specific name `principal name: tu02612` from my log-entry,  
i trid this costum pattern `[\s principal name:](?<bensl_name>[a-z0-9]{5,7})[\s]` but i didn't get any thing right.  
some thing like this:

```
{
  "bensl_name": [
    [
      "tainer"
    ]
  ]
}

```

my log file looks like this:

```
17/18 18:23:52:414 CEST] 000000e7 SystemOut O 1116543205 [WebContainer : 19] ERROR filenet_error.engine.com.filenet.apiimpl.transport.RequestBroker - method name: checkNameCollision principal name: tu02612 Global Transaction: true User Transaction: false Exception Info: A uniqueness requirement has been violated.

	at com.filenet.engine.persist.FolderPersister.handleException(FolderPersister.java:246)

```

i m not able to parse just the content of principal name: `tu02612` in the bensl\_name field. Can any one help!!!

What about `%{GREEDYDATA} principal name: %{WORD:bensl_name}` ?
