A list for people interested in developing the OVAL language.
View all threadsI'm writing some content, and obtaining data from textfilecontent54 subexpression, and it has some undesirable data that I'd like to quickly replace with the "correct" data, before using in another object. I was thinking that I might be able to replicate the functionality of a 'replace' with a combination of a split and concat, but after looking at other samples of concat, I don't think I'm going to end up with a single string.
If anyone has any methods in OVAL to replace a substring and make a new string I'd appreciate it. I'm hoping to be flamed, that I missed something trivial, so feel free to blast away.
I'm parsing the deployment.config file in Java 8 to see what the path is to the https://protect-us.mimecast.com/s/lhvZCXDXgmCVPRmU66CfK?domain=deployment.properties file is, but they intentionally use forward slashes instead of backslashes on Windows. While using forward slashes in Windows filepaths may work, I didn't wasn't to assume it would work as expected in all SCAP tools, as a valid Windows path.
Input:
C:/Windows/Sun/Java/Deployment/deployment.properties
Desired Output:
C:\Windows\Sun\Java\Deployment\deployment.properties
If I split my original string with /, I suspect I'll get back a variable with
C:
Windows
Sun
Java
Deployment
https://protect-us.mimecast.com/s/lhvZCXDXgmCVPRmU66CfK?domain=deployment.properties
If I then concat each with \ I'll end up with
C:\
Windows\
Sun\
Java\
Deployment\
https://protect-us.mimecast.com/s/7ZZ8CYEYjoSEWq5sGbzOQ?domain=deployment.properties (which I don't want either...)
Then I'm unsure if or how to glue my multiple element variable back to a single string.
So, just checking to see if I'm offtrack or if a regex replace substring function would be useful in OVAL?
Thanks,
Jack Vander Pol
Hi Jack,
I was going to suggest: "why not use the ReplaceFunctionType" … but then I discovered there simply is no such thing! I feel like someone proposed this before, but perhaps I only dreamed it.
I can’t think of any other way to achieve what you want to do. Do you want to write up a proposal for a new function?
Best regards,
