I'd like to filter the content of a log of a pom.xml file using a regex.
I created it on regexr and it works using PCRE; this is my regex:
commit \K[a-z0-9]*(?=[\s\S]*\+.*<version>1.2.0)
I then tried to run with the following commands:
git log --full-history -p pom.xml | grep -P "commit \K[a-z0-9]*(?=[\s\S]*\+.*<version>1.2.0)"
and
git log --full-history -p pom.xml | perl -nle 'print \$1 if /commit \K[a-z0-9]*(?=[\s\S]*\+.*<version>1.2.0)/'
but neither of them worked (nothing seems to match).
I'm surely missing something, but I cannot figure out what.
EDIT:
To clarify, this is an example of git log:
commit a1357f4e1cb2c34aa1a1357f4e1cb2c34aa1471f

I want to pick the hash of the commit where version changed to a certain value (1.2.0 in the regex I wrote).
Obviously, this being the log of all the commits done on a certain repository, there may be more than one commit as well.
Using the aforementioned regex on this input should output the commit hash:
a1357f4e1cb2c34aa1a1357f4e1cb2c34aa1471f
This is what actually happens using regexr.
