Dear Community,

here's my second question as a complete noob to programming. Having explored command line editing, I am now seeking help with an intricate regex pattern.

This is the issue. I have a large file (approx. 1 Gb). In the file the name in the attribute creationid and changeid have to be changed to a particular string.

Whenever I run the script and compare the files via diff command they turn out to be identical.

I checked my regex with the Tool Expresso, but I think Perl's regex works differently.

This is the string in question: 

<tu creationdate="12345Z" changedate="6789Z" creationid="John Doe" cha
+ngeid="" lang="de-DE">

[download]

changeid might also contain a name

This is the script I've been using in order to replace creationd id.  perl -pi.bak -e 's{creationid=".+?"}{creationid="Simon Simonsen"}g;' file.xml

I also tried s{creationid="([^<+])"} as alternative pattern

I appreciate any help on how to improve this script to work through this monstrous file

Thanks a mil in advance

C.
