Thank you all for your feedback.

In context: I'm trying to write a script that I can use to selectively remove data sources from XML dumps from an RRD file.
I.e. When a datasource is obsolete and needs removed to avoid polluting the graph.

This first section of the script is to get the names of the datasources. I'll now start the next part of my script, to push them to an array.

Each of your answers is useful to help develop my own perl knowledge (and hopefully anyone else finding this thread.).
Thanks again for your help.

Regards -
