Pretty-prints XML on the commandline (requires groovyserv)

ppxml

#!/usr/bin/env groovyclient

println(prettyPrintXml(System.in.text))

def prettyPrintXml(text) {
    def xmlNode = new XmlParser().parseText(text)
    def writer = new StringWriter()
    def printer = new XmlNodePrinter(new PrintWriter(writer))
    printer.preserveWhitespace = true
    printer.print(xmlNode)
    writer.toString().trim()
}

ppxml - Pretty-print XML on the command-line

Usage

echo '<person><name>Leonard</name></person>' | ppxml

Output:

Leonard

Installation & Deps

Put it on your path and install groovyserv.

Alternative: If you don't want groovyserv you can use ordinary groovy instead, the dowside is that execution will take a lot longer.

Known issues

The current approach parses the xml before it formats it which means a parse fail will result in an error. Let me know if this is an issue.
