Boolean - class com.japisoft.xpath.function.basic.Boolean.
function converts its argument to a boolean as follows:
a number is true if and only if it is neither positive or negative zero nor NaN
a node-set is true if and only if it is non-empty
a string is true if and only if its length is non-zero
an object of a type other than the four basic types is converted to a boolean in a way that is dependent on that type
Boolean() -
Constructor for class com.japisoft.xpath.function.basic.Boolean
C
Ceiling - class com.japisoft.xpath.function.basic.Ceiling.
function returns the smallest (closest to negative infinity) number that is not less than the argument and that is an integer
Ceiling() -
Constructor for class com.japisoft.xpath.function.basic.Ceiling
Lang - class com.japisoft.xpath.function.basic.Lang.
The lang function returns true or false depending on whether the language of the context node as specified by xml:lang
attributes is the same as or is a sublanguage of the language specified by the argument string.
Lang() -
Constructor for class com.japisoft.xpath.function.basic.Lang
Last - class com.japisoft.xpath.function.basic.Last.
Return a number equal to the context size from the expression
evaluation context.
Last() -
Constructor for class com.japisoft.xpath.function.basic.Last
function returns the argument string with whitespace normalized by stripping leading
and trailing whitespace and replacing sequences of whitespace characters by a single
space.
Not() -
Constructor for class com.japisoft.xpath.function.basic.Not
Number - class com.japisoft.xpath.function.basic.Number.
function converts its argument to a number as follows:
a string that consists of optional whitespace followed by an optional minus sign followed by a Number followed by whitespace is
converted to the IEEE 754 number that is nearest (according to the IEEE 754 round-to-nearest rule) to the mathematical value
represented by the string; any other string
is converted to NaN boolean true is converted to 1; boolean false is converted to 0
a node-set is first converted to a string as if by a call to the string function and then converted in the same way as a string argument
an object of a type other than the four basic types is converted to a number in a way that is dependent on that type
function returns the substring of the first argument starting at the position specified in the second argument with length specified in the third argument.
The substring-after function returns the substring of the first argument string that follows the first occurrence of the second argument string in the first argument string, or the empty string if the first argument string does not contain the second argument string.
function returns the substring of the first argument string that precedes the first
occurrence of the second argument string in the first argument string, or the empty string if the first argument string
does not contain the second argument string.
returns the first argument string with occurrences of characters in the second argument
string replaced by the character at the corresponding position in the third argument string.
