mime-content

A node.js module for parsing strings based on MIME Type.


Usage

This module supports parsing strings for a small handful of common MIME Types. Pull requests for adding additional types
are welcome.

After parsing a HTML string, CSS selectors can be used to query the parsed content. The cheerio module
is used to query the DOM. Selectors supported by JQuery can be used.

Use the toString() function to retrieve the un-parsed content.

``javascript
var content = require('mime-content');

var html = content('

Header!

html('h1.big').text();
=> 'Header!'
`

After parsing a JSON string, a regular object is returned. Use the toString() function on that object to retrieve
the un-parsed content.

`javascript
var content = require('mime-content');

var json = content('{"foo":"bar"}', 'application/json');

json.foo
=> 'bar'
`

Both the application/xml and text/xml MIME Types are supported.

After parsing a XML string, the xmldom document is available. Also, XPath support is
provided by the xpath module. All DOM 3 XPath expressions
are supported.

By default, the XML parser assumes your XPath expression is looking for a single DOM node so it returns the first match
in the document. If you'd like all matching nodes instead, use the second optional boolean parameter with your query. Pass
true to return all matching nodes.


`javascript
var content = require('mime-content');

var xml = content('Bob SmithJimmy Dean', 'text/xml');

xml.xpath('/people/person/name/text()').data;
=> 'Bob Smith'

xml.xpath('/people/person/name/text()', true).map(function(text) {
return text.data;
});
=> ['Bob Smith', 'Jimmy Dean']

xml.xpath('/people/person/@id', true).map(function(attr) {
return attr.value;
});
=> ['123', '456']
`


The toObject() function uses xml2js to return an object representation
of the XML. This function accepts an options object that is passed directly to the xml2js Parser. See the xml2js Readme for
the supported options.

`javascript
var xml = content('Bob SmithJimmy Dean', 'text/xml');
xml.toObject({explicitArray: false, explicitRoot: false, mergeAttrs: true});
=>
{
person: [
{ id: '123', name: 'Bob Smith' },
{ id: '456', name: 'Jimmy Dean' }
]
}
`

After parsing a application/x-www-form-urlencoded string, a regular object is returned.

`javascript
var content = require('mime-content');

var qs = content('foo=bar&foo=baz&baz=bip', 'application/x-www-form-urlencoded');

qs.foo
=> ['bar', 'baz']

qs.baz
=> 'bip'
