The xmlindent command formats and adds indenting to XML so that it is easier to read. Indenting is currently set to 3 spaces.
If an XML file name is not specified, the XML to indent will be read from standard output. Otherwise, one or more file names can be specified:
xmlindent /path/to/xml
xmlindent /path/to/first-xml /path/to/second-xml
The formatted XML from each file will be printed in the order in which the files were specified.
By default, extra whitespace may be added to CDATA elements. To preserve the contents of CDATA elements:
xmlindent -valid /path/to/xml
