How to XML in VB.NET

XML, standing for Extensible Markup Language, serves as a versatile and widely used tag-based language in various domains. Its primary purpose lies in facilitating the seamless transfer and storage of data across diverse applications. Similar to HTML, XML falls under the umbrella of SGML, or Standard Generalized Markup Language, which serves as a foundational standard for defining markup languages.

Platform independence

One of the notable advantages of XML is its platform independence, enabling information formatted in XML to be effortlessly utilized across different operating systems and computing platforms. This characteristic allows for the seamless exchange and interoperability of data between various software systems, regardless of the underlying technologies and infrastructures.


XML boasts a self-describing nature, which means that it not only encapsulates data but also encapsulates the rules and metadata required to interpret and comprehend the information it contains. This self-describing aspect makes XML highly transparent and intuitive, enabling both humans and machines to easily understand the structure, content, and meaning of the data represented in XML format.

XML files

XML files are structured using tags that enclose data within a start tag and an end tag. These tags serve as containers for specific information. For instance, let's consider the creation of an XML tag called "Header." In this case, the start tag would be represented as "<Header>", while the end tag would be represented as "</Header>". Any desired information can be placed between these tags to populate the "Header" section.

Tag-based structure

This tag-based structure is a fundamental aspect of XML files, allowing for the organization and representation of data in a hierarchical manner. The start and end tags delimit the boundaries of the data associated with a particular tag, ensuring clear differentiation between different sections or elements within the XML file.

< Header > Header Content Here < /Header >

While creating an XML file , some important points have to remember :

* XML is case sensitive

ex: < Header > is not same as < HeadeR > * Tags must be closed in the reverse order that they were opened

ex : < first-tag >< second-tag > Data here < /second-tag > < /first-tag >

Sample XML File


XML file format

XML file format is extensively supported by the .NET technology stack. The robust .NET Framework offers a comprehensive set of classes and functionalities specifically designed for performing various operations on XML formatted files. These classes reside within namespaces such as System.Xml, System.Xml.Schema, System.Xml.Serialization, System.Xml.XPath, and System.Xml.Xsl. Notably, XML serves as the internal storage format for datasets in ADO.NET.

Creating an XML file

Creating an XML file is a straightforward process that can be accomplished using any text editor. XML files possess the unique characteristic of being human-readable, making it easy for developers and users to comprehend their structure and contents. Simultaneously, XML files are also machine-readable, allowing for seamless data processing and interoperability between different software applications.
