wp2js

Parse the XML file exported in wordpress to a readable javascript object. The properties of the object can be filtered.

Installation

Install wp2js is easy, just use npm. Then execute the below command:

npm install wp2js

Usage

It is simple to use it, just like this:

var wp2js = require('wp2js');

wp2js.parse('wordpress.data.xml', function(err, data){
    /**
     * By default, the structure of the `data` object is like the below:
     *  {
     *      generator: 'http://wordpress.org/?v=3.8.4',
     *      title: 'Alex Chao',
     *      link: 'http://www.xiaocaoge.com',
     *      description: 'A frontend',
     *      language: 'zh-CN',
     *      siteUrl: 'http://www.xiaocaoge.com',
     *      blogUrl: 'http://www.xiaocaoge.com',
     *      authors: [Object],
     *      categories: [Object],
     *      tags: [Object],
     *      posts: [Object],
     *      pages: [Object],
     *      attachments: [Object]
     *  }
    */
    // ...
});

Note: The property name is shorten, such as wp:base_site_url >> siteUrl, wp:post_id >> id, content:encoded >> content, etc.

Or you can pass a configurable object as the first argument:

wp2js.parse({
    source: 'wordpress.data.xml',
    encoding: 'utf8', // The utf8 is default
}, function(err, data){
    // ...
});

Or you can filter the properties:

Note: It has a default filter level, see the #opts.

wp2js.parse({
    source: 'wordpress.data.xml',
    // Only the `categories` and `tags` are included in the `data` object
    filterConfig: ['categories', 'tags',]
}, function(err, data){
    // ...
});

Or you can filter out some properties of data.

wp2js.parse({
    source: 'wordpress.data.xml',
    filterConfig: {
        categories: false,
        tags: false
    }
}, function(err, data){
    // ...
});

You can even filter the properties of the object as the element in categories or tags.

wp2js.parse({
    source: 'wordpress.data.xml',
    filterConfig: {
        categories: ['id', 'name'],
        tags: ['id', 'name']
    }
}, function(err, data){
    // ...
});

In the same way, you can filter out some properties of the object as the element in categories.

wp2js.parse({
    source: 'wordpress.data.xml',
    filterConfig: {
        categories: {
            parent: false,
            name: false
        }
    }
}, function(err, data){
    // ...
});

At last, you can output the full data in the XML file.

wp2js.parse({
    source: 'wordpress.data.xml',
    filterConfig: 'full'
}, function(err, data){
    // ...
});

Options

At present, it only provides an asynchronous method - wp2js.parse(opts, callback).
