I have this large XML file on my drive. The file is too large to be opened with sublimetext or other text editors. 
It is also too large to be loaded in memory by the regular XML parsers.
Therefore, I dont even know what's inside of it!
Is it just possible to "print" a few rows of the XML files (as if it was some sort of text document) so that I have an idea of the nodes/content? 
I am suprised not to find an easy solution to that issue.
Thanks!
This is one of the few things I ever do on the command line: the "more" command is your friend. Just type

more big.xml
how to print the first lines of a large XML?
