Format an XML document. More information: https://xmlstar.sourceforge.net/doc/UG/xmlstarlet-ug.html#idm47077139569312.

• Format an XML document, indenting with tabs:

xml {{[fo|format]}} {{[-t|--indent-tab]}} {{path/to/input.xml|URI}} > {{path/to/output.xml}}

• Format an HTML document, indenting with 4 spaces:

xml {{[fo|format]}} {{[-H|--html]}} {{[-s|--indent-spaces]}} {{4}} {{path/to/input.html|URI}} > {{path/to/output.html}}

• Recover parsable parts of a malformed XML document, without indenting:

xml {{[fo|format]}} {{[-R|--recover]}} {{[-n|--noindent]}} {{path/to/malformed.xml|URI}} > {{path/to/recovered.xml}}

• Format an XML document from stdin, removing the DOCTYPE declaration:

cat {{path\to\input.xml}} | xml {{[fo|format]}} {{[-D|--dropdtd]}} > {{path/to/output.xml}}

• Format an XML document, omitting the XML declaration:

xml {{[fo|format]}} {{[-o|--omit-decl]}} {{path\to\input.xml|URI}} > {{path/to/output.xml}}

• Display help:

xml {{[fo|format]}} --help
