Load jQuery libraries in a Google Sheet javascript app

[Fritz Praus]

I have an XML file that I would like to read and populate a Google spreadsheet. I would like to use jQuery because of all the great functions jQuery provides to traverse XML. Every example I see that uses jQuery being loaded is into a Web page. I am not using a web page. I trying to have a script that runs from inside the sheet. Does anyone have a code snippet that would share with me that demonstrates jQuery being loaded. I have read the Google documentation, the topic is pretty light.

 

Thanks
