I have a very large xml file around 1.9M lines of xml that I would like to do the following:

1. Use two TAGs under the root of the file to create a timestamp that ALL events in step two will use.

2. Create an events using the timestamp created in step one for all data between tag measInfo

I want to combine ReportStartDate and ReportStartTime to create a timestamp that all newly created events will use (Data between measInfo Tags)

Is this possilbe?

Thanks in advance.
