StrReplace

Replaces the specified substring with a new string.

ReplacedStr := StrReplace(Haystack, Needle , ReplaceText, CaseSense, &OutputVarCount, Limit)

Parameters

Haystack

Type: String

The string whose content is searched and replaced.

Needle

Type: String

The string to search for.

ReplaceText

Type: String

If blank or omitted, Needle will be replaced with blank (empty), meaning it will be omitted from the return value. Otherwise, specify the string to replace Needle with.

CaseSense

Type: String or Integer (boolean)

If omitted, it defaults to Off. Otherwise, specify one of the following values:

On or 1 (true): The search is case-sensitive.

Off or 0 (false): The search is not case-sensitive, i.e. the letters A-Z are considered identical to their lowercase counterparts.

Locale: The search is not case-sensitive according to the rules of the current user's locale. For example, most English and Western European locales treat not only the letters A-Z as identical to their lowercase counterparts, but also non-ASCII letters like Ä and Ü as identical to theirs. Locale is 1 to 8 times slower than Off depending on the nature of the strings being compared.

&OutputVarCount

Type: VarRef

If omitted, the corresponding value will not be stored. Otherwise, specify a reference to the output variable in which to store the number of replacements that occurred (0 if none).

Limit

Type: Integer

If omitted, it defaults to -1, which replaces all occurrences of the pattern found in Haystack. Otherwise, specify the maximum number of replacements to allow. The part of Haystack to the right of the last replacement is left unchanged.

Return Value

Type: String

This function returns the replaced version of the specified string.

Remarks

The built-in variables A_Space and A_Tab contain a single space and a single tab character, respectively. They are useful when searching for spaces and tabs alone or at the beginning or end of Needle.

RegExReplace, InStr, SubStr, StrLen, StrLower, StrUpper

Examples

Removes all CR-LF pairs from the clipboard contents.

A_Clipboard := StrReplace(A_Clipboard, "`r`n")

Replaces all spaces with pluses.

NewStr := StrReplace(OldStr, A_Space, "+")

Removes all blank lines from the text in a variable.

Loop
{
    MyString := StrReplace(MyString, "`r`n`r`n", "`r`n",, &Count)
    if (Count = 0)  ; No more replacements needed.
        break
}
