node-xml2js
Description
Simple XML to JavaScript object converter. Uses sax-js.
See the tests for examples until docs are written.
Note: If you're looking for a full DOM parser, you probably want
JSDom.
Installation
Simplest way to install xml2js
is to use npm, just npm install xml2js
which will download xml2js and all dependencies.
Simple usage
var fs = require('fs'),
xml2js = require('xml2js');
var parser = new xml2js.Parser();
parser.addListener('end', function(result) {
console.dir(result);
console.log('Done.');
});
fs.readFile(__dirname + '/foo.xml', function(err, data) {
parser.parseString(data);
});
Options
Apart from the default settings, there is a number of options that can be
specified for the parser. Options are specified by new Parser({optionName: value})
. Possible options are:
explicitCharkey
(default: false
)trim
(default: true
): Trim the whitespace at the beginning and end of
text nodes.normalize
(default: true
): Trim whitespaces inside text nodes.explicitRoot
(default: false
): Set this if you want to get the root
node in the resulting object.emptyTag
(default: undefined
): what will the value of empty nodes be.
Default is {}
.explicitArray
(default: false
): Always put child nodes in an array if true;
otherwise an array is created only if there is more than one.
These default settings are for backward-compatibility (and might change in the
future). For the most 'clean' parsing, you should disable normalize
and
trimming
and enable explicitRoot
.
Running tests, development
The development requirements are handled by npm, you just need to install
them. We also have a number of unittests, they can be run using zap
directly from the project root.
