Link parkin’: XMLStarlet
XMLStarlet is a set of command line utilities (tools) which can be used to transform, query, validate, and edit XML documents and files using simple set of shell commands in similar way it is done for plain text files using UNIX grep, sed, awk, diff, patch, join, etc commands.
XMLStarlet is a venerable Swiss Army Knife for carving up XML. I was
having some issues with xmllint checking Discogs Data XML
files for well-formedness and stumbled upon XMLStarlet. On initial
test drive, seemed to be doing a bit better with the large size of the
Discogs files.
