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:
“Those things which now most engage the attention of men, as politics and the daily routine, are, it is true, vital functions of human society, but should be unconsciously performed, like the corresponding functions of the physical body.”
—Henry David Thoreau (1817–1862)
“There is no such thing as a language, not if a language is anything like what many philosophers and linguists have supposed. There is therefore no such thing to be learned, mastered, or born with. We must give up the idea of a clearly defined shared structure which language-users acquire and then apply to cases.”
—Donald Davidson (b. 1917)
