Can you use xml in html

can I use XML for AJAX in a website created using HTML5

I am new to web programming and just started learning XML and AJAX. I am creating a social gaming website for my college project. I am confused at the point of using XML for AJAX in HTML5. As XHTML is replaced by HTML5 so is it ok to use XML or i should choose JSON (i know nothing about JSON but it is what I found in answers on web to the question related to choice between JSON and XML). My preference is XML because it is in my syllabus but I want to make sure that XML and HTML5 will not conflict.

Did you ever check what AJAX is an acronym for? The XHR API? The markup language won’t affect the code, and if you control both ends of the client server relationship then code with what you are happy with for now.

You can use any kind of serialized data, XML, JSON, CSV, INI. JSON seems to be standard de facto this days, since it’s much more readable and native to JavaScript.

1 Answer 1

You can encode the data sent to the server in any format you want and not interfere with the web page’s standards.

The idiomatic thing to do is to just use JSON these days, but that is up to you.

It’s also important to note that if you use a non HTML5 tag, the police aren’t going to show up at your door and, unless your professor validates your site using a tool, he probably won’t notice and it will render just fine.

Certain things in your page like
being more HTML5 compatible than
will break XML compatibility, if that’s what your asking. But the standard still leaves a clause allowing full XML compatibility in order to allow any page to comply with XML, AFAIK. Though, from the discussion in that thread, this is explicitly for backwards compatibility purposes with the older HTML standards.

XML and HTML are two important languages used in web development. While HTML is used for structuring and formatting web content, XML is used for storing and exchanging data. Embedding XML in HTML can help separate data from HTML and make it easier to update data without changing the HTML file. In this blog post, we will discuss how to embed XML in HTML and display XML data on an HTML page.

CDATA for Character Data

CDATA is used for embedding character data into XML, not embedding XML into HTML. Examples of character data include text, numbers, and symbols. CDATA is useful for preventing XML parsing errors when using special characters. When you need to include special characters in your XML document, you can use CDATA to wrap them. For example, to include the ampersand (&) symbol in an XML document, you can use the following syntax:

This will prevent the XML parser from interpreting the ampersand symbol as the beginning of an entity reference.

Linking XML to HTML

To link an XML file to an HTML page, there are two common methods: server-side includes and embedding XML content inside a element.

Server-Side Includes

Server-side includes allow for dynamic loading of XML files. This means that you can update the XML file without having to edit the HTML page. To use server-side includes, you need to have access to a server that supports it. Here is an example of how to include an XML file using server-side includes:

This will include the contents of the data.xml file in the HTML page.

Embedding XML Content in a Element

Embedding XML content in a element can be useful for smaller XML files. Here is an example of how to embed XML content in a element:

How to embed an XML file in HTML?

Displaying XML Data on an HTML Page

There are several ways to display XML data on an HTML page. The most common way is to use XSLT, which is a standard way to transform XML data into HTML. Another way is to send formatted XML data as a string from a Java service. jQuery can also be used to easily embed XML content into an HTML page.

XSLT

XSLT is a standard way to transform XML data into HTML. It uses a stylesheet to define how the XML data should be transformed into HTML. Here is an example of an XSLT stylesheet that transforms an XML document into an HTML table:

To apply the stylesheet to an XML document, you need to add a processing instruction to the XML document:

This tells the XML parser to use the stylesheet.xsl file to transform the XML data.

Sending Formatted XML Data as a String from a Java Service

If you’re working with a Java web application, you can send formatted XML data as a string from a Java service. Here is an example of how to do this:

String xml = "Hello, World!"; String formattedXml = formatXml(xml); request.setAttribute("xml", formattedXml); 

In this example, the formatXml method formats the XML string and returns it. The xml string is then added as an attribute to the HTTP request, which can be accessed from the JSP page.

jQuery

jQuery can be used to easily embed XML content into an HTML page. Here is an example of how to use jQuery to load an XML file and display it on an HTML page:

$(document).ready(function() < $.ajax(< type: "GET", url: "data.xml", dataType: "xml", success: function(xml) < $(xml).find("item").each(function() < var item = $(this).text(); $("body").append("
" + item + "
"); >); > >); >); 

This code loads the data.xml file using AJAX and loops through each item element in the XML document. It then appends each item to the body of the HTML page.

Tag in HTML

The tag can be used to insert XML code into an HTML file, but it is not an XML element. Using the tag can cause compatibility issues with some browsers. It is generally recommended to use other methods for embedding XML in HTML.

Raw XML View in Browser

Raw XML files can be viewed in all major browsers, but they will not be displayed as HTML pages. Viewing raw XML can be useful for debugging and troubleshooting. Using XSLT or other methods to display XML on an HTML page is recommended for a better user experience.

Conclusion

Embedding XML in HTML can help separate data from HTML and make it easier to update data without changing the HTML file. Different methods for embedding XML in HTML include server-side includes, elements, and XSLT. Displaying XML on an HTML page can be done using XSLT, sending formatted XML data as a string, or using jQuery. By using the appropriate method, you can easily display XML data on an HTML page and provide a better user experience.

How Can XML be Used?

XML is often used to separate data from presentation.

XML Separates Data from Presentation

XML does not carry any information about how to be displayed.

The same XML data can be used in many different presentation scenarios.

Because of this, with XML, there is a full separation between data and presentation.

XML is Often a Complement to HTML

In many HTML applications, XML is used to store or transport data, while HTML is used to format and display the same data.

XML Separates Data from HTML

When displaying data in HTML, you should not have to edit the HTML file when the data changes.

With XML, the data can be stored in separate XML files.

With a few lines of JavaScript code, you can read an XML file and update the data content of any HTML page.

Transaction Data

Thousands of XML formats exist, in many different industries, to describe day-to-day data transactions:

• Stocks and Shares
• Financial transactions
• Medical data
• Mathematical data
• Scientific measurements
• News information
• Weather services

Example: XML News

XMLNews is a specification for exchanging news and other information.

Using a standard makes it easier for both news producers and news consumers to produce, receive, and archive any kind of news information across different hardware, software, and programming languages.

An example XMLNews document:

How to Use XSLT to Display XML Data on an HTML Webpage

To view XML data as part of a webpage, you can utilize XSLT; browsers do not provide this capability on their own.

XML is a language used to structure, store, and exchange data. XSLT is another language that allows you to transform your XML data into other formats, such as HTML.

You can use XSLT to display XML data on an HTML webpage. Using XML and XSLT to display your data can be useful, as it allows you to structure the data in a way that makes sense for your specific needs.

How to Add Example Data to an XML File

To display XML data on a webpage, you first need to create the XML file and add data to it.

1. Create a new file called data.xml.
2. Inside the XML file, declare the encoding and XML version:

 

games> 
game> 
name>The Last of Us Part II name> 
developer>Naughty Dog developer> 
game> 
game> 
name>Ghost of Tsushima name> 
developer>Sucker Punch Productions developer> 
game> 
game> 
name>Death Stranding name> 
developer>Kojima Productions developer> 
game> 
games> 

How to Use XSLT to Read Data From the XML File

Create a new XSL file to loop through each data point in the XML page and display the data.

1. In the same folder as your XML file, create a new file called xmlstylesheet.xsl.
2. Inside the file, declare the XSL version, and add the basic XSL tag structure:

 
xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
// Your code here 
xsl:stylesheet> 

xsl:template match="/"> 
html> 
body> 
// Your HTML code in here 
body> 
html> 
xsl:template> 

xsl:for-each select="games/game"> 
 
xsl:for-each> 

xsl:value-of select="name" />
xsl:value-of select="developer" /> 

How to Display Data on an HTML Webpage

You will not be able to open the XSLT or XML file directly in the browser to view the data as part of a webpage. Create a new HTML file, and render the data using an iframe tag.

1. In the same folder as your XML and XSL files, create a new file called index.html.
2. Add the basic structure of an HTML file. If you have not used HTML before, you can brush up on introductory HTML concepts.
