Namespaces in XML XML name space

Reading: Name space in x m l
Alias:
XML name space
Field:

When the plural languages which are defined with XML are handled in one document, the modifier which is used in order to avoid the fact that name of the element and attribute collides.

XML is metalanguage, it is possible to draw up various markup languages by the fact that the tag and attribute are defined in the document, DTD. These mean to use properly according to purpose, but it can also describe one document in plural markup languages. At that time, when the same tag name is defined with plural languages, when that tag appears in the document, whether it is something which is defined with some language the necessity to distinguish occurs. This time one by one to describe URI of DTD to the tag, because, it is redundant, being difficult, the language which you use (URI where DTD is put) with it defines the prefix meaning which corresponds at the forefront of the document, it distinguishes by adding that prefix meaning to the head in the tag. Between prefix meaning and tag name “: ” (The colon) with to divide, “<en: verb>” “<ja: Like verb>” you use.

NaN Non number

Full spelling: Not a Number
Field:
Programming > coding > NaN

It is used in field of programming, the special numeric representation which shows the fact that it stops being the result where the operational result is normal.

When division will be done with 0, exponent of negative number tries to be sought, as for the result infinity and it reaches the value which cannot be defined. In this kind of case, generating error depending upon language processing system, you discontinue the program, but there are times which return special numeric representation continue processing as the result. The expression which is used at that time is NaN.

Detecting error and exception, rather than describing coping method, whether or not the result NaN the one which is decided increases processing efficiency, there are times when description becomes simple. In addition, using NaN, furthermore doing operation, whether or not as for the result because it becomes NaN, after doing complicated processing, finally the result NaN inspecting, the description that it diverges processing, is possible.
