For those who work with XML files regularly, opening such files with ease to view the data they contain will only make out work easier as we can work a lot faster with little or no inhibitions. Just in case you didn't know, there are several ways to open XML files.

Using only one method may not always be in your best interest, so read on to find out other ingenious ways to open them.

What is an XML File?

Before we proceed, it will be wise for us to first understand in technical detail what an XML file is.

XML stands for Extensible Markup Language. These are basically standard ASCII text based files and hence can be opened or edited using any standard text editor. These files use tags for defining objects as well as objects attributes. These XML files are formatted in a similar manner as HTML documents but usually contain custom tags which have no meaning in HTML for defining of the custom data they are meant to hold.


XML files have picked up popularity in the recent past due to their ease of parsing and small size enables them for ease of transferring over the internet quickly. XML files are used very commonly today in technologies such as SOAP, Web Services, AJAX, etc where the underlying data is all communicated to and from the servers in XML files.

For starters, it is a language markup curated by the W3C (World Wide Web Consortium) to define a selected series of syntax for document encoding.

These codes are readable by both humans and computers through tags. Similarly to Hypertext Markup Language (HTML), which also uses shortcodes, the only difference is that XML uses a longer and more extensive code to describe its format.

What’s more? the users can use their own special markups to describe their own content in a defining way. This, along with its ease of use, is one of the reasons why this format is widely used by many. To clearly distinguish HTML from XML, let’s say that

  • HTML is used for content presentation
  • XML is used as a dedicated storage platform for data language description 

Some common document formats that use XML include 

  • ATOM and RSS – Describe how your reader handles news feeds
  • Microsoft.NET – Is used to configure files 
  • Microsoft Office 2007 and Subsequent Versions – Structures documents. Eg. What X represents in.DOCX

Associate the XML file extension with the correct application. You may right-click on the XML file and click on "Open with" - "Choose another app." Then, select another program and check the box "Use this app always to open

1. Use a Text Editor

If you work with XML files all the time, you can hasten the process by using a Text Editor. However, you should know that a lot of Editors are not designed to display your XML files in a proper structure. What this means is that the file will come out differently from what you are often used to. Text Editors are best used to open them so as to take a quick look. To use a Text Editor, just do the following.

  • Right-click the file you wish to open
  • Point your cursor to “Open With” on the menu
  • Click “Notepad”

This action will open the XML file within seconds.

NB: Text Editors are suitable for glancing the data in the XML file. If you want to work extensively with or on their data, an Editor may not be an ideal tool.

2. Use your Web Browser 

If you do not intend to edit the XML file, you can use a Web Browser to view the structured data it contains. You can even use the browser you are using to read this article to view the file or files. It may also interest you to know that most browsers have default settings, which are set as a default viewer for XML files. To open with a Web Browser, follow these steps.

  • Double click the XML file with your cursor 
  • When the file opens, it will display a structured data
  • Scroll through the data to view

NB: The data will be clear to see but will not be as colorful as what is obtainable with Notepad++.


3. An Online Editor

Some very good Online Editors are


These websites can enable you to view and edit your XML files. Once you are done with the edition, you can then re-download the file or convert it to a different format of your choosing.


4. Use the XML- JSON for conversion 

Another very easy way to open a XML file is to the following 

  • Use the Export to CSV key to saving your file in comma-separation
  • You can also use the download command to download changes made to the XML file


These four steps above are very simple steps to open and even convert your XML files.

Although you can use any of them, it is often best to use the option that offers you the best results based on your personal preference. If you only want to view the xml file, it is best to use a Text Editor or a Web Browser.

Open XAPK File

.XAPK file is categorized as a compressed file and comes in the zip format. It is a special package used for installing android apps on any mobile device. The file has a similarity to the standard .APK file .

However, it may also contain several other assets that are used by the app to be downloaded, egg a .OBB file; this file is responsible for storing several programs, like media files, graphics, and several other apps.

The .XAPK file is used to distribute apps on a third-party Android app that you have downloaded from the internet. The file is, however, not supported by Google Play.

Installer package

.XAPK file is not a standard app installer package. As a result, it must be manually installed or the installation must be done using a XAPK installer.

After you have downloaded the .XAPK file, the app can still be installed to your Android device with the aid of a XAPK installer.

If you prefer you install any additional file manually, you can get the XAPK file unzipped first and then move the unzipped files to the right location on your mobile device.

It is, however, difficult to deliver the apps through Google Play since the size of the concerned APK file must not be more than 50MB.

This is forcing apps developers to go for other files for storing additional media assets and graphics, like the OBB file mentioned earlier.

Due to the limitation mentioned above, some of the developers publicize their apps on several other sites aside from Google Play. The .XAPK format can be used for packaging the OBB and APK files together to bring about a seamless installation and delivery process when an android app is being downloaded from a site that is not Google Play.

Before you download the file in the XAPK format from any external source aside from Google Play, you should first verify if that website is trustworthy or not since it is possible to distribute malware and even spyware through .XAPK files.


How to open .XAPK files

You can open XAPK file on your android device by using the APKPure app. If you are using Windows Operating System, on the other hand, you can use Pure APK Install to open the .XAPK file on your Windows device.

If you do not have access to any of the programs mentioned above for opening the .XAPK, you can install the file manually by changing the file extension.

In this case, you need to:

  1. First open the .XAPK file.
  2. Then launch the File Manager.
  3. Locate the .XAPK file and change the name of the extension to .ZIP.
  4. You can then navigate to Google Play to download the RAR app.
  5. Next, copy the .obb file into any location you prefer and install the APK.
  6. after which the app will collect the resources automatically from the OBB data file and it will open as intended.

It is equally possible to open the file using your PC. You will need to first download Pure APK Install on your PC before you can do this.

One other helpful app for opening the .XAPK file is the Uptodown App.

One commonly file format today is an XFL File. In this piece, we will show how to open an XFL file to view what it contains. 

XFL files are generally associated with Adobe Systems (Flash). When Adobe introduced their CS4 products, they came in a new exchange format, the XFL. XFL files are ZIP archives that contain the source materials for any Flash document. Inside the XFL file is an XML file that describes the documents in such a manner that Adobe Flash can read.

The XML file inside the XFL zip archive also provides descriptions for other constructs and contents in the document.

What is an XFL File for?

The purpose of creating an XFL file is to provide an avenue for other programs to create their own Flash files. And to also exchange the data source for such files. For example, it can be for modify images in an archive without disrupting the timeline.

How to open an XFL file?

To open an XFL file, you will need to install a software like Adobe Flash on your device.
