XMLStarlet is a command line tool for manipulation of XML. It exposes XPath, XSLT, and validation among many other capabilities. On FreeBSD, it is generally invoked as <tt>xml</tt> and is available from the Ports Collection in <tt>textproc/xmlstarlet</tt>; on Linux, it is generally invoked as <tt>xmlstarlet</tt> (throughout the rest of this article, I will use <tt>xml</tt>). XMLstarlet invocations take the form: <tt>xml command [command options] [filename]</tt>. It is intended for use within pipelines; any diagnostic output generated will be placed on stderr. To get help on a command, run <tt>xml command --help</tt>.<br> | XMLStarlet is a command line tool for manipulation of [[XML]]. It exposes XPath, XSLT, and validation among many other capabilities.
