Xul scripts

Xul is a set of XML scripts written in Python.

• ppx: pretty print XML

• xp: select XML nodes with XPath

• transform: transform XML with XSLT

• validate: validate XML with XSD, DTD or RELAX NG

Installation

Xul command line scripts can be installed with pip:

  -V, --version         show program's version number and exit
  -m, --method          use ElementTree.xpath method instead of XPath class

                        only names of files with a false or NaN result, or without a result,
                        are written to standard output
