This is my user agent
Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31
I know I am using chrome, so I understand it is from chrome version 26. But what is the rest of the information?
How can I read the string. And what all I can collect from userAgent?
What is the best way to parse the userAgent and read each property in it?

The format of the User-Agent string in HTTP is a list of product tokens (keywords) with optional comments. For example, if a user's product were called WikiBrowser, their user agent string might be WikiBrowser/1.0 Gecko/1.0. The "most important" product component is listed first.
The user agent is an HTTP header that web browsers and other web applications use to identify themselves and their capabilities. Your web security software captures and logs user agent data when users browse the Internet.
A user agent is any software that retrieves and presents Web content for end users or is implemented using Web technologies. User agents include Web browsers, media players, and plug-ins that help in retrieving, rendering and interacting with Web content.
The userAgent property returns the user-agent header sent by the browser to the server. The userAgent property is read-only. The value returned, contains information about the browser name, version and platform. The web specification suggests that browsers should provide as little header information as possible.
From developer.mozilla.org:
User-Agent: <product> / <product-version> <comment> Common format for web browsers: User-Agent: Mozilla/<version> (<system-information>) <platform> (<platform-details>) <extensions>
<product> A product identifier <product-version> A version number of the product. <comment> Zero or more comments containing sub product information, for example.

Mozilla/5.0 (Macintosh; Intel Mac OS X x.y; rv:42.0) Gecko/20100101 Firefox/42.0
The Chrome (or Chromium/blink-based engines) user agent string is similar to the Firefox format. For compatibility, it adds strings like "KHTML, like Gecko" and "Safari".
