xml command [options] files

xml is the main command of XMLStarlet, a comprehensive command-line XML toolkit for querying, editing, validating, and transforming XML documents. It provides a set of subcommands that cover common XML processing tasks without requiring a full programming language.
Key subcommands include val for validating XML against DTDs or schemas, fo for pretty-printing and reformatting XML, sel for selecting data using XPath expressions, ed for editing XML elements and attributes in place, and tr for applying XSLT transformations. Each subcommand has its own set of options tailored to its specific operation.
XMLStarlet is designed for shell scripting and automation, allowing XML processing tasks to be integrated into pipelines and build scripts. It reads from files or stdin and writes to stdout, following Unix conventions for composability.
