XML preguntas y respuestas de entrevista

Question: Why should I use XML?

• XML can be used to describe and identify information accurately and unambiguously, in a way that computers can be programmed to understand (well, at least manipulate as if they could understand).
• XML allows documents which are all the same type to be created consistently and without structural errors, because it provides a standardised way of describing, controlling, or allowing/disallowing particular types of document structure. [Note that this has absolutely nothing whatever to do with formatting, appearance, or the actual text content of your documents, only the structure of them.]
• XML provides a robust and durable format for information storage and transmission. Robust because it is based on a proven standard, and can thus be tested and verified; durable because it uses plain-text file formats which will outlast proprietary binary ones.
