pjxml

Pure JavaScript XML (pjxml)

This package provides a very lightweight, forgiving XML parser. It's 100% JavaScript and while it is Node-compliant it has no package dependencies.

Parsing - Plain JavaScript

Include pjxml.js then call the parse() method. For a full example, see the index.html demo page in the pjxml GitHub repository.

var xml = '<document attribute="value"><name>David Bowie</name></document>';
var doc = pjXML.parse(xml);

Parsing - Node.js

Install the pjxml package, then include it using require.

var pjXML = require('pjxml');

var xml = '<document attribute="value"><name>David Bowie</name></document>';
var doc = pjXML.parse(xml)

the document tree

The parse() function returns a hierarchical object tree with each element mapped to one object. The text and element contents of each element are stored in an array in the content property. Any attributes are in the attributes property.

finding things

The select function supports a very minimal XPath selection syntax. It returns an array of all elements that match the path given. If only one node matches, it returns a single node instead of an array. The selectAll method always returns an array.

The // operator matches recursively.

For example:

var el = doc.selectAll('//name');

returns

[{"type":1,"content":["David Bowie"],"name":"name","attributes":{}}]

extracting text

The text() method returns all text content for a given element and its children:

console.log(doc.text());

returns

David Bowie

extracting XML

The xml() method returns valid XML for any given document or element object.

console.log(doc.xml());

returns

<document attribute="value"><name>David Bowie</name></document>
