Can I use Find/Replace in Files to find files that do NOT contain a string?

Hi,
I am working with library catalog metadata and we need to identify items from a set of almost 40,000 that do not contain a specific value, e.g. "UFIR" in <mods:aggregation></mods:aggregation>. Some suggestions I found online pointed to using regex but none of the offered examples worked. Any help would be very much appreciated.

Hi,
I would probably attempt to use XPath for this.
The Oxygen XPath toolbar has a drop down in which you can decide to run the XPath over multiple files or over the entire project.
For example I might try an XPath like this:
//*:aggregation[not(contains(text(), 'UFIR'))]
