What is XML format?
XML is also known as Extensible MarkupLanguage (roughly translated as extended markup language). This is a markup language that functions to transmit data and describe various types of data.
The effect of XML files
The main purpose of XML is to simplify data sharing between different platforms and systems, especially those connected to the Internet. Therefore, XML has a great effect in sharing and exchanging data between systems.
Characteristics of XML
- XML is used for structured data.
- Visually, XML is quite similar to HTML.
- Although it is text, XML is not readable.
- XML is usually very long.
- XML is considered a bridge to bring HTML to XHTML.
- XML is a module.
- XML is also considered the basis for RDF and the Semantic Web.
- XML is copyright free, platform independent and very well supported.
Advantages of XML
- The biggest advantage of XML is its independence (independent data). This is easy to understand, because XML is used to describe data in text, so most software or normal programs can read them.
- XML can read and analyze data sources quite easily, so it is used with the main purpose of exchanging data between different programs and systems.
- Can create an XML file with no effort.
- XML is used for the Remote Procedure Calls to serve website services.
Cons of XML
The error rate when using XML to transfer data is up to 5%, even 7%. This number is not too high, but in fact, people still need to consider before using it to exchange information.

- Content : The main content of the card.
- </nodename> : The closing tag, the name, the content of this tag and the opening tag must match.
