Re: Witango-Talk: @REPLACE

Just sent a demo to witango customer support. The @replace works fine with strings that originate in witango. My problem is that strings that come from documents that are read from files, it does not do well. Since the documents were originally written by witango on OS X - on a box that doesn't have OS9 even (xserve), it's puzzling that the character set would be something from the previous OS. I don't know why this doesn't work, just that it doesn't.

Roland,
Can you try the following code:

<@ASSIGN request$mystring "The quick brown fox jumps over the lazy dog.">
<@ASSIGN request$myStr1 "<@SUBSTRING STR='<@VAR request$mystring>' START='11' NUMCHARS='5'>">
<@ASSIGN request$myStr2 "red-brown and white">
<@ASSIGN request$EmptyStr "">
Original String:<@VAR request$mystring> 
Str1:[<@VAR request$myStr1>] 
Str2:[<@VAR request$myStr2>] 
 
Paint the Fox 
<@REPLACE STR="<@VAR request$mystring>" FINDSTR="<@VAR request$myStr1>" REPLACESTR="<@VAR request$myStr2>"> 

Clean the Fox 
<@REPLACE STR="<@VAR request$mystring>" FINDSTR="<@VAR request$myStr2>" REPLACESTR="<@VAR request$myStr1>"> 

Colourless Fox 
<@REPLACE STR="<@VAR request$mystring>" FINDSTR="<@VAR request$myStr1>" REPLACESTR="<@VAR request$EmptyStr>"> 

Do you get this result:

Original String:The quick brown fox jumps over the lazy dog.
Str1:[brown]
Str2:[red-brown and white]

Paint the Fox
The quick red-brown and white fox jumps over the lazy dog.
Clean the Fox
The quick brown fox jumps over the lazy dog.
Colourless Fox
The quick fox jumps over the lazy dog.

If you do not get the same results can you use this code to produce a test case which highlights your problem and send it to us off-list.

Following on from what Ben suggested, one area where you may find issues with @replace is on OS X. ?With the change to OS X Apple changed the character encoding of the OS so the witango server uses the standard Latin-1 character encoding of OS X while T2K used the MacRoman encoding of OS 9. ?If the string you are searching was encoded as MacRoman or came from a datasource that has had data inserted as MacRoman the characters may not match if they are above ascii 127. ?This would appear as a problem with @REPLACE when in fact it is an issue with the data. ?Look at some of your strings in an editor and look for byte values above 127. ?You should then be able to determine what the strings encoding was.
