Uses a regular expression (RE) to search a string for a pattern,
starting from a specified position. The search is
case-insensitive.
string.reFindNoCase( reg_expression=string, start=number, returnSubExpressions=boolean, scope=string, multiline=boolean )
Returns: any
| Argument |
Description |
|
reg_expression
string,
required
|
Regular expression for which to search. Case-insensitive.
|
|
start
number,
optional
|
A positive integer. Position in the string at which to start search. The default value is 1.
|
|
returnSubExpressions
boolean,
optional
|
True: if the regular expression is found, the first array
element contains the length and position, respectively,
If the regular expression contains parentheses that
group subexpressions, each subsequent array element
contains the length and position, respectively, of
the first occurrence of each group.
If the regular expression is not found, the arrays each
contain one element with the value 0.
False: the function returns the position in the string
where the match begins. Default.

|
scope
string,
optional
|
One: (Default)Returns the first value that matches the regex
All: Returns all values that match the regex
|
|
multiline
boolean,
optional
|
If true indicate the regular expression should treat input as having multiple lines.
This option affects the interpretation of the ^ and $ metacharacters.
When true the ^ metacharacter matches at the beginning of every line, and the $ metacharacter matches at the end of every line.
Additionally the . metacharacter will not match newlines when true.
