Package Exports

xml2o
xml2o/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (xml2o) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

xml2o

Helps you convert XML into an object for easy reading.

Getting Started

Install the package:

npm i -S xml2o

Let's convert XML from stream:

import {convertStream} from 'xml2o';
import {createReadStream} from 'fs';

const node = convertStream(createReadStream('/path/to/file.xml'));

We can doing same with string:

import {convertString} from 'xml2o';

const node = convertString('<node><foo bar="bar">foo</foo></node>');

Examples

A SimpleXML-like Node object made to help you read XML structures in JS without DOM.

Check a node

import {convertString} from 'xml2o';

const xml = `<node>
    <foo bar="bar">foo</foo>
    <list>
        <baz id="1" name="baz 1" />
        <baz id="2" name="baz 2" />
        <baz id="3" name="baz 3" />
    </list>
</node>`;

const node = convertString(xml);
console.log(node);

Root of a node, name and inner text

console.log(
    node.name,
    node.text
);

Child node name, text and attributes

console.log(
    node[0].name,
    node[0].text,
    node[0].getAttribute('bar'),
    node[0].getAttributeNode('bar'),
    node[0].getAttributes()
)

Node children

console.log(...node.map(child => child.name));

Node query

import {convertString} from 'xml2o';

const xml = `<node>
    <a/>
    <b>
        <a/>
        <a/>
        <c><a/></c>
    </b>
    <d>
        <c><a/></c>
    </d>
</node>`;

const node = convertString(xml);
console.log(node.query('/a')); // found /node/a
console.log(node.query('a')); // found /node/a, /node/b/a, /node/b/c/a, /node/d/c/a
console.log(node.query('c/a')); // found /node/b/c/a, /node/d/c/a
console.log(node.query('/d/c')); // found /node/d/c
console.log(node.query('b/a')); // found /node/b/a

Documentation

Method	Arguments	Return	Description
convertString	`XMLString`	`Node`	XML string
convertStream	`stream`	`Node`	Readable stream

Node

Node class used to present XML nodes as objects. Every Node object has following properties and methods:

Properties

Property	Description
`name`	Tag name
`local`	Tag local name
`prefix`	Tag prefix
`parent`	Parent Node
`root`	Root Node

Methods

Method	Arguments	Return	Description
`getAttribute`	`name, uri?`	`string`	Returns an attribute value
`getAttributeNode`	`name, uri?`	`Attribute`	Returns an attribute
`getAttributes`		`Array<string>`	Returns an array of attributes values
`hasAttribute`	`name, uri?`	`boolean`	Returns true if an attribute is exists
`query`	`name, uri?`	`Array<Node>`	Returns matched nodes in any level

Note

Code examples written with modules so you may need babel, typescript or other to run its or rewrite ES6 imports to:

const createString = require('xml2o').createString;

This library written in ES6 and if you need ES3 build you can tell me i'll make support for older JS versions.
