New code should strongly consider {{#invoke:string|replace}} or {{#invoke:MultiReplace|main}}. For backward compatibility, both the input and pattern string are trimmed of surrounding whitespace before processing begins. This means you cannot remove three instances of "the " from "the the the thing"; instead you will remove one instance of "the".
Space normalization is a related string manipulation where in addition to removing surrounding whitespace, any sequence of whitespace characters within the string is replaced with a single space. Space normalization is performed by the function named Trim() in spreadsheet applications (including Excel , Calc , Gnumeric , and Google Docs ), and ...
This template trims leading and trailing (but not interior) whitespace from a string. The string should be passed as the first unnamed parameter. The parameter must be named |1= if its value contains a = character. You may substitute this template—that is, if this template is used as {}, the resulting wikicode is "clean".
The template trims matched pairs of leading and trailing single and double quotes from a string. Template parameters Parameter Description Type Status String 1 The string to be trimmed String required See also {{ trim }}
For example, double (or more) spaces within text are collapsed to a single space, and spaces which appear on either side of the "=" that separates an attribute name from its value have no effect on the interpretation of the document. Element end tags can contain trailing spaces, and empty-element tags in XML can contain spaces before the ...
In CSV implementations that do trim leading or trailing spaces, fields with such spaces as meaningful data must be quoted. 1997,Ford,E350," Super luxurious truck "Double quote processing need only apply if the field starts with a double quote. Note, however, that double quotes are not allowed in unquoted fields according to RFC 4180.
Any string containing only whitespace or no characters at all will be treated as false. Undefined parameter values are tricky: if the first positional parameter was not defined in the template call, then {{{1}}} will evaluate to the literal string "{{{1}}}" (i.e., the 7-character string containing three sets of curly braces around the number 1 ...
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
