Functions Defined By XSLT
The following functions can occur in many XSLT attributes, such as xsl:value-of.select and xsl:for-each.select.
| Function | Description/ Syntax | Example |
|---|---|---|
| ceiling | The ceiling function returns the smallest integer that is equal to or is larger than the numeric value of the number argument. | ceiling(3.57) |
| concat | Concatenates two or more strings, which are listed in the parentheses | concat($fname,’ ‘, $lname) |
| count | The count function counts and returns the number of nodes in a node-set. | count(elements) |
| floor | The floor function returns the largest integer that is equal to or is smaller than the numeric value of the number argument. | floor(3.57) |
| normalize-space | Removes white-space from the beginning and end of the string | normalize-space($fname) |
| position | The position function returns the position number in the current node list of the node that is currently being processed by an xsl:for-each or xsl:apply-templates element. There are no arguments. | position |
| round | The round function rounds a number to its closest integer. | round(3.57) |
| string | The string function converts the value argument to a string. | string |
| string-length | The string-length function returns the number of characters in a string. The string argument is optional. If omitted, the default is to use the string value of the context node. | string-length(‘hello’) |
| substring | A segment within a variable value. Substring takes three parameters: the input variable, the first character to be selected, and the length of the resulting string | substring($dob,4,2) |
| substring-after | The substring-after function returns a portion out of the string specified in the string argument that occurs after the substring specified in the substring argument. | substring-after(‘In 1814 we took a little trip’, ‘we’) |
| substring-before | The substring-before function returns a portion out of the string specified in the string argument that occurs before the substring specified in the substring argument. | substring-before(‘In 1814 we took a little trip’, ‘we’) |
| sum | The sum function adds and returns the total value of a set of numeric values in a node-set or list of values. | sum(1,3,7,12) |
| translate | Takes the string in the value argument, replaces all occurrences of a string specified in the string1 argument with substitute characters specified in string2 argument and returns the modified string. | translate(‘colored armor’, ‘or’, ‘our’) |

Famous quotes containing the words functions and/or defined:
“Mark the babe
Not long accustomed to this breathing world;
One that hath barely learned to shape a smile,
Though yet irrational of soul, to grasp
With tiny finger—to let fall a tear;
And, as the heavy cloud of sleep dissolves,
To stretch his limbs, bemocking, as might seem,
The outward functions of intelligent man.”
—William Wordsworth (1770–1850)
“For a large class of cases—though not for all—in which we employ the word “meaning” it can be defined thus: the meaning of a word is its use in the language.”
—Ludwig Wittgenstein (1889–1951)
