Reader
View the XML document using a simple text editor or any browser. Most major browsers support XML. XML files can be opened in the browser by double-clicking the XML document (if it is a local file) or entering the URL path in the address bar (if the file is located on the server). You can also open other files in the browser in the same way. XML files are saved with the ".xml" extension.

Let's explore the various ways in which you can view XML files. The following example (sample.xml) applies to all chapters in this chapter.


XML/HTML CodeCopy content to clipboard

  1. <?xml version="1.0"?>
    <contact-info>
        <name>Tanmay Patil</name>
        <company>TutorialsPoint</company>
        <phone>(011) 123-4567</phone>
    </contact-info>
    Copy after login
