# Viewing XML Files

Raw XML files can be viewed in all major browsers.

Don't expect XML files to be displayed as HTML pages.

## Viewing XML Files

<?xml version="1.0" encoding="ISO-8859-1"?>
- <note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

Look at this XML file: note.xml

The XML document will be displayed with color-coded root and child elements. A plus (+) or minus sign (-) to the left of the elements can be clicked to expand or collapse the element structure. To view the raw XML source (without the + and - signs), select "View Page Source" or "View Source" from the browser menu.

Note: In Netscape, Opera, and Safari, only the element text will be displayed. To view the raw XML, you must right click the page and select "View Source"

## Viewing an Invalid XML File

If an erroneous XML file is opened, the browser will report the error.

Look at this XML file: note_error.xml

## Other XML Examples

Viewing some XML documents will help you get the XML feeling.

An XML CD catalog
This is a CD collection, stored as XML data.

An XML plant catalog
This is a plant catalog from a plant shop, stored as XML data.

A Simple Food Menu
This is a breakfast food menu from a restaurant, stored as XML data.

## Why Does XML Display Like This?

XML documents do not carry information about how to display the data.

Since XML tags are "invented" by the author of the XML document, browsers do not know if a tag like <table> describes an HTML table or a dining table.

Without any information about how to display the data, most browsers will just display the XML document as it is.

In the next chapters, we will take a look at different solutions to the display problem, using CSS, XSLT and JavaScript.
