XML configuration file - extracting elements

[Gary Hinger <Ga...@wildtangent.com>]

Is there a way to extract elements from log4net's XML configuration
file, without reopening the file and parsing it?

 

For example, I'd like to get a certain appender's "file" property, so
that I can create the logging directory every time logging is done. I
need to do this to support runtime changes in the directory
specification in config xml. Since the log4net assembly is designed to
watch the file, it would be a shame to have to reparse the file in
separate code.

 

Also, is there a way to get log4net to create directories as necessary
when logging? This would solve my immediate problem. Thanks.

You can get a list of appenders by calling GetAppenders:

 IAppender[] appenders = LogManager.GetRepository().GetAppenders();

If you need to modifiy an appender at run-time, you should be able to
find the appender using the above code, modify the appender, then call
ActivateOptions to re-initialize it.

The FileAppender automatically creates the directory structure if it
does not exist (lines 400 and 533 of FileAppender.cs are calls to
Directory.CreateDirectory(string)).
