What is the main difference between XML and HTML?
The key difference between HTML and XML is that HTML displays data and describes the structure of a webpage, whereas XML stores and transfers data. XML is a standard language which can define other computer languages, but HTML is a predefined language with its own implications.
What are the properties of GML?
GML 1.0 defines Simple Properties such as strings, numbers, and Boolean values, and Geometric Properties such as points and lines. GML 1.0 was a major initiative in the geospatial domain, but more importantly, it served as a stepping stone towards the development of a more robust language.
What are GML coordinates?
Coordinates in GML represent the coordinates of geometry objects. Coordinates can be specified by any of the following GML elements: GML has multiple ways to represent coordinates.
Where is GML used?
The GML format is often used for webservice data calls (API). For geographical purposes we recommend using a GML or a KML. AN XML is a good format language for just data purposes.
Can XML replace HTML?
No. XML itself does not replace HTML: instead, it provides an alternative which allows you to define your own set of markup elements. HTML is expected to remain in common use for some time to come, and a Document Type Definition for HTML is available in XML syntax as well as in original SGML.
Why is XML better than HTML?
XML provides framework to define markup languages. HTML can ignore small errors. XML does not allow errors. HTML is not Case sensitive.
