Replace only exact phrase

[IchBistTod]

Okay I want to replace only an exact phrase in a string.

Example:

"dog ate dog2"

When I want to just replace "dog" with "the dog" I get

"the dog ate the dog2"

when I want.

"The dog ate dog2"

So it will only replace if the whole word matches.

Do you understand what I am saying?

Thanks for help.

Try this :

$text1 = 'dog ate dog2'
$replaced = StringReplace ($text1,'dog','the dog',1)
ConsoleWrite ($replaced)

Try this :

$text1 = 'dog ate dog2'
$replaced = StringReplace ($text1,'dog','the dog',1)
ConsoleWrite ($replaced)

Not acceptable. Sorry.

Text may need to be replaced more than 1 time.

like

"Dog ate dog2 and dog was happy"

then needs to be

"The dog ate dog2 and the dog was happy"

You see better now what I am meaning?

[JRowe]

$text1 = 'dog ate dog2 and dog died of indigestion, dawg.'
$replaced = StringRegExpReplace($text1, "(dog )|( dog )", " the dog ")

ConsoleWrite($replaced)

Something like that. You might have to do two passes.

StringReplace and StringRegExpReplace both work with whitespace. You could refine the regex to work with beginning of the string, and to exclude partial matches inside strings like bulldog and hotdog, if they exist.

this will be acceptable

$text1 = ' dog ate dog2 and dog died of indigestion, dawg. Hotdog bulldog.'
$replaced = StringRegExpReplace($text1, "( dog )", " the dog ")

ConsoleWrite($replaced&@CRLF)

as in my code nothign needs replace that is the very first word.

thank you.

I actually make it work this way.

But how would I make it so it only replace exact word like

test

test1

replace with

aha

and have

aha

test1

not

aha

aha1

$sReplaced = StringRegExpReplace($sStr, "(?i)\btest\b", "aha")

[IchBistTod]

$sReplaced = StringRegExpReplace($sStr, "(?i)\btest\b", "aha")

Edit:

With a few modifcation, it does work perfect =]/
