Best Practice - Read file, edit contents, write new file

Hello all,

I am after some best practice advise relating to reading a text file, replacing some information and then writing the data to a new file.

As an example, my source file contains:



com.iplanet.services.debug.level=message

com.iplanet.services.debug.directory=c:/Path/To/Debug



com.iplanet.am.naming.url=https://naming.com/url

com.iplanet.am.naming.ignoreNamingService=true



com.iplanet.am.server.protocol=https

com.iplanet.am.server.host=naming.com

com.iplanet.am.server.port=443



com.iplanet.am.notification.url=http://localserver.com:3700/LocalService/service.svc



com.iplanet.am.cookie.name=iPlanetDirectoryPro

com.iplanet.am.cookie.encode=true



com.iplanet.am.jssproxy.trustAllServerCerts=true



com.iplanet.am.version=6.1



com.iplanet.security.SecureRandomFactoryImpl=com.iplanet.am.util.SecureRandomFactoryImpl

com.iplanet.security.SSLSocketFactoryImpl=netscape.ldap.factory.JSSESocketFactory

com.iplanet.security.encryptor=com.iplanet.services.util.JCEEncryption



com.sun.identity.webcontainer=IAS7.0
I need to change the line:

com.iplanet.services.debug.directory=c:/Path/To/Debug
to be

com.iplanet.services.debug.directory=c:/NewPath/Somewhere/Else
and 

com.iplanet.am.notification.url=http://localserver.com:3700/LocalService/service.svc
to 

com.iplanet.am.notification.url=http://localserver.com:3700/NewName/service.svc
I originally started of with something like this:



ClearErrors

FileOpen $0 "${sourcefile}" r

FileRead $0 $1

FileClose $0



${WordReplace} $1 "c:/Path/To/Debug" "c:/NewPath/Somewhere/Else" "E+" $R0

${WordReplace} $R0 "/LocalService/" "/NewName/" "E+" $R1



ClearErrors

FileOpen $0 "${targetfile}" w

FileWrite $0 $1

FileClose $0
However this resulted in some weird results (the target file only contained the first line of the source file)

So after hunting around the wiki I haven't found a definitive way of doing this. So can anybody point me in the right direction.

EDIT : After some further hunting, I came across the following:



Which seems to work. All I need to do is copy the source for to the target location and then use these functions to make the edits.

use ReadIniStr to read the path as it will be easier. then use Copy to copy the file(s) to the target location and then use WriteIniStr to change it in the file.

You cannot use ReadINIStr if there are no section headers. Use ConfigWrite instead.

I did try config write however one of the changes I needed to work it would have required some workarounds.

In summary this line in the source file:

[code]
com.iplanet.am.notification.url=http://localserver.com:3700/NewName/service.svc
[code]

The "localserver.com" is unique for every install, so I need to keep that and only change the "/NewName/" part. So I would have had to use configread, then do string replacement, then a config write. Due to this, in the end it was easier to use the item in the edit. Unless of course there is a "gotcha" somewhere that I haven't spotted.

i have the same problem, i uused configread and configwrite, and he changed the first entry, he fond. but the entry i want to change, can be more then one times in the File. And he should be change every entry.

How can i change the other entrys, or why he change only one entry?

ok now i have exactly the same Problem and cant use writeinistr, because i have no [Sections]

and if i use Configwrite, he adds it at the end of the File. but i want to replace a substring 



  ... test@"Database name" ...
i want change the database name.
