Hello,
I have a file hashname path generated in my tests as below. It has '/' for directory path, underscore and hyphens in random positions in file name. I want to replace this entire path using regular expression in my JPO.

What I have tried:

I tried

Java

getReplacementMap().put("regex:<[a-zA-Z0-9\\/]+[-_a-zA-Z0-9_-]+[^:]+>", "<HASHNAME>");

It is not replacing the below path and filename.

hashname: dc/c8/dcc8kixy0huy4ebs_agumhcu-qt_fcsvxn_9if3e13o.hen

Any ideas for regex?

You have a period (.) you're not accounting for? (I'm no expert)

Hi Gerry, the (.) is needed for the file extension.

The problem is not necessarily where you think it is.
Use tools to see what part of RegEx matches what part of string, you may find surprises.

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx: Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx: Regexper[^]

Thank you so much for all the links to tools and information. I will save for future.
I had tried this tool ((https://www.freeformatter.com/regex-tester.html) before trying in my JPO. But what worked in the tool didn't work in my JPO.

Solution 1

Check this solution. Find a string using regex with forward slashes in it[^]
Further, you can use this link to generate and test your regular expression. RegExr: Learn, Build, & Test RegEx[^]

Only a pleasure.

Solution 3

You can achieve your goal by simplifying it all -
Remove unnecessary angle brackets, simplify the character class for your directory and file name, still included the dot '.' in the character class for your file extension -

Java

getReplacementMap().put("regex:[a-zA-Z0-9_/]+[-_a-zA-Z0-9.-]+", "<HASHNAME>");

This one replaced the entire test output with <hashname>
I tried below and it worked!

getReplacementMap().put("regex:[a-zA-Z0-9]+/[a-zA-Z0-9]+/[a-zA-Z0-9_-]+[_-]+[a-zA-Z0-9_-]+[^.]+\\.[a-zA-Z0-9]+", "<hashname>");

Thank you Andre.

Solution 5

getReplacementMap().put("regex:[a-zA-Z0-9]+/[a-zA-Z0-9]+/[a-zA-Z0-9_-]+[_-]+[a-zA-Z0-9_-]+[^.]+\\.[a-zA-Z0-9]+", "<HASHNAME>");

Can you try this

getReplacementMap().put("regex:[^/]+/[a-zA-Z0-9_-]+[_-]+[a-zA-Z0-9_-]+[^.]+\\.[a-zA-Z0-9]+", "<HASHNAME>");

This gave a very close solution. The path gets generated every time, so obviously the directories will be different.
When I tried your regex, it substituted as below...

d7/<hashname>

The first dir name was not substituted. So I tried below which worked!!

getReplacementMap().put("regex:[a-zA-Z0-9]+/[a-zA-Z0-9]+/[a-zA-Z0-9_-]+[_-]+[a-zA-Z0-9_-]+[^.]+\\.[a-zA-Z0-9]+", "<hashname>");

Thank you so much Manish!
