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).

      files: {
        "tmp/compile.html": ["test/fixtures/compile.xml"],
      },
    },
  },
});

Directory of files

grunt.initConfig({
  xsltproc: {
    options: {
      stylesheet: "test/fixtures/compiler.xsl",
    },
    compile: {
      files: [
        {
          expand: true,
          cwd: "test/fixtures",
          src: "*.xml",
          dest: "tmp",
          ext: ".html",
        },
      ],
    },
  },
});

Passing parameters

grunt.initConfig({
  xsltproc: {
    options: {
      stylesheet: "test/fixtures/compiler.xsl",
      params: {
        fav: '/catalogue/album[@id="3"]/title',
      },
    },
    compile: {
      files: {
        "tmp/compile.html": ["test/fixtures/compile.xml"],
      },
    },
  },
});

Passing string parameters

grunt.initConfig({
  xsltproc: {
    options: {
      stylesheet: "test/fixtures/compiler.xsl",
      stringparams: {
        title: "My Music",
      },
    },
    compile: {
      files: {
        "tmp/compile.html": ["test/fixtures/compile.xml"],
      },
    },
  },
});

XInclude

Process the input document using the XInclude specification.

grunt.initConfig({
  xsltproc: {
    options: {
      stylesheet: "test/fixtures/compiler.xsl",
      xinclude: true,
    },
    compile: {
      files: {
        "tmp/compile.html": ["test/fixtures/compile.xml"],
      },
    },
  },
});

Process the stylesheet using the XInclude specification.

grunt.initConfig({
  xsltproc: {
    options: {
      xincludestyle: true,
    },
    compile: {
      options: {
        stylesheet: "test/fixtures/compiler.xsl",
      },
      files: {
        "tmp/compile.html": ["test/fixtures/compile.xml"],
      },
    },
  },
});

filepath

Process the input documents and using the filepath xsl:param.

grunt.initConfig({
  xsltproc: {
    compile: {
      options: {
        stylesheet: 'test/fixtures/template_filepath.xsl'
        filepath: true
      },
      files: [{

        cwd: 'test/fixtures',
        src: '*.xml',
