XML Introduction

XML stands for eXtensible Mark-up Language. This is a mark-up language which is easy to use to store and transfer the data between programs. XML has its own defined structure and main advantage of XML is that you can pull the data from a database and convert into XML and that XML can be given as input for any program to display it for easy processing. There is no need to download any software to test or practice XML because , the browser in your computer is enough to do so.

 

XML Application:

XML formats are used in many areas to display the data contained in XML format. Most used areas are Stocks, Mathematical Data, Scientific values and weather data and Financial Transactions

So, Let’s not wait anymore to learn XML with the cutting-edge topics listed below.

 

Understanding Syntax & Basic Program in XML:

Many confuse with HTML and XML. Let me clear it here, HTML is Hyper Text Mark-up Language which is used for design web pages where as XML extensible Mark Language is used for store or carry the data in simple format.It is just the markup language which holds the data between tags. Learn more..

 

What are the documents in XML?

XML Document forms the full struture of xml formatted data composed with prolog and root element nested with other elements.There would be only one root element, where root element encloses many other elements inside the final inner element holds the data. XML Document can be divided as three components. Learn more..

 

What are the Elements in XML?

XML Element is the main component which holds the data from start tag till end tag. XML document consists one or more elements enclosed in root element. Elements naming represent the self-explanatory form of data inside it. Elements contains attributes which are used to specify additional information about the element. Learn more..

 

What are the entities in XML?

The Document entity is the starting point of XML processor and it is the symbolic representation of information. There are certain rules that both in HTML and XML to not to use few symbols as content or data which requires to indicate them differently.The Syntax of an entity starts with ampersand (&) then name of the symbol and ending with semicolon. Learn more..

 

Understanding Tags in XML:

XML tags are the starting and ending points of an element. They are basic things to know before we are writing a XML code. For every starting tag there should be an ending tag in the correct order. Learn more..

 

Understanding Attributes in XML:

XML attributes are parameters with key-value pair syntax in an element. An element can have multiple attributes. If you have basic understanding about HTML you might have experienced the attributes like id=”class=” . In the same way the XML will have attributes in an element. Learn more..

 

Understanding Comments in XML:

XML Comment is used to mention the brief description or the small note about the XML code. Even though the elements are self-descriptive, we may require the comment at some places. There is no difference between HTML comments and XML comments syntax. Both will have same syntax. Learn more..

 

Understanding Prolog in XML?

XML Prolog is the component added in the beginning of an XML document. Otherwise, we can say that whatever it appears before the document’s root element can be considered as Prolog. XML Prolog includes XML declaration, DOCTYPE and comments, processing instructions too. Learn more..

 

Understanding Nesting in XML:

XML Nested elements means the element within the element. The structure starts with root element within that another element that follows accordingly. Root element is the most outer element. Inside the root element, all the other elements mentioned can have the inner elements. Learn more..

 

How to determine validation in XML?

XML validation involves in to determine if the XML document is valid and well-formed. Here, we need understand that even a word document may contain errors while typing the information. Validating a word document involves in ensuring that the information entered in the document is grammatically correct with right alignment of paragraphs. In XML document, we need to validate if it well-formed and valid. Learn more..

 

How to determine Processor in XML?

XML processor generally represented as XProc which processes the XML documents. Sometimes it is called XML promise. usually, every code needs to compiled or interpreted by processor in the background.In the same way for XML documents Xproc will be the single processing model for all XML documents. Learn more..

 

How to determine Namespaces in XML?

XML namespaces are generally used for naming the elements and attributes uniquely. They are defined in W3C recommendation.In XML, the data enclosed with in elements and those elements naming sometimes may match with reserved words like body, head in XHTML. Learn more..

 

Understanding Tree in XML:

XML family tree structure depicts the ancestor or descendant elements, parent elements, child elements and we can segregate them as branches also for our understanding. Anyhow, there should be one root parent element for any other child elements and parent elements nested inside. Learn more..

 

Understanding Ancestor in XML:

XML family tree can understand better with some relations between elements hierarchy. We know that elements within the elements is the regular structure of XML which consists one root element for all. Every inner element will have one or more outer elements which can be identified as Ancestors. Learn more..

 

Understanding Descendant in XML:

In the XML family tree , descendant can be identified as the inner element of every outer elements in the hierarchy. For suppose, if we have 2 elements called element A , element B and if the element A is the outer element of element B, then element B will be called as descendant of element A. Learn more..

 

Understanding Parent in XML:

In the XML family tree , parent can be identified as the outer element of any other inner elements in the hierarchy. For suppose, if we have 2 elements called element A , element B and if the element A is the outer element of element B, then element A will be called as Parent of element B. Learn more..

 

Understanding Child in XML:

In the XML family tree , child can be identified as the inner element of any other outer element in the hierarchy.For suppose, if we have 2 elements called element A , element B and if the element A is the outer element of element B, then element B will be called as child of element A. Learn more..

 

What are Sibling in XML?

In the XML family tree , sibling can be identified as the element which is in the same hierarchy of any other element in the XML document. For suppose, if we have 3 elements called element A , element B, element C and if the element A is the outer element of both element B and element C then element C will be called as sibling of element B.
