grunt-xsltproc

Apply XSLT stylesheets to XML documents.

Getting Started

This plugin requires Grunt >=0.4.1

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-xsltproc --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-xsltproc');

The "xsltproc" task

Overview

Run this task with the grunt xsltproc command.

xsltproc

xsltproc is an open-source command line tool for applying XSLT stylesheets to XML documents.

This task requires you to have xsltproc installed. If you're on OS X or Linux you probably already have it installed. You can check by running xsltproc -version in your terminal.

Setup

First, ensure you have xsltproc installed. Then, in your project's Gruntfile, add a section named xsltproc to the data object passed into grunt.initConfig().

grunt.initConfig({
  xsltproc: {
    options: {
      // Task-specific options go here. 
    },
    your_target: {
      // Target-specific file lists and/or options go here. 
    }
  }
})

Options

options.stylesheet

Type: String or false

Path to the XSLT stylesheet to apply to the files. If options.stylesheet evaluates to false, xsltproc will fallback to stylesheets linked from the target document.

options.params

Type: Object

Pass an object of parameter name/value pairs to the stylesheet. Parameters are passed directly to the xsltproc call with the --param flag.

options.stringparams

Type: Object

Pass an object of string parameter name/value pairs to the stylesheet. Parameters are passed directly to the xsltproc call with the --stringparam flag.

options.xinclude

Type: Boolean

Process the input document using the XInclude specification. More details on this can be found in the XInclude specification.

options.xincludestyle

Type: Boolean

Process the stylesheet using the XInclude specification.

options.novalid

Type: Boolean

Process the input document skipping the DTD loading phase.

options.filepath

Type: Boolean

Pass the grunt filepath as stringparam to the XSLT.

options.html

Type: Boolean

The input document is(are) an HTML file(s).
