XML stands for extensible markup language. It defines those set of rules that are used to encode a document that is readable by both human and machine. Its designs goals mainly focus on usability, generality and simplicity over internet but its wide use is for representing arbitrary data structures.
XML syntax has been used in many documents including RSS, XHTML etc. Its basic implementation has been seen in communication protocols, file configuration in Microsoft .Net framework. XML has also been a major part in implementation of registry for Apple. Its common use is for interchanging data over internet.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .XML file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .XML file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .XML file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .XML extension. Directly on this website you can find a solution of the most common problem with the .XML file – that you do not have on your computer the appropriate program to open the file.
