Re^7: Regex Optional capture doesn't (updated)

More like a perverse obsession.

Thanks for your tip on "use re 'debug'".

It shows that the RE gets confounded by the <Unwanted> tag.
Removing that tag allows the regex to capture both items I want.

However, this is not an option while I'm parsing the log.

All power corrupts, but we need electricity.

my proposition from the edit here works for me with your data: `DB<132> p $x <blah1 phase="2" type="MyType" more_keys="Values" <Unwanted/> <SomeTa +gIwant><k1="v1"></SomeTagIwant> DB<133> $re = qr/\btype="([^"]+)".+?<(\w+TagIwant\b\|$)/ DB<134> print join "\|", $x =~ $re MyType\|SomeTagIwant` [download] update `DB<154> p $x <blah1 phase="2" type="MyType" more_keys="Values" <Unwanted/> <SomeTa +gIwant><k1="v1"></SomeTagIwant> DB<155> p $y <blah1 phase="2" type="MyType" more_keys="Values" <Unwanted/> DB<156> $re = qr/ \btype = "([^"]+)" .+?

Excellent - your "Update" one works ! The pre-update fails when the tag is absent. I saw this the same time as hauxex's working solution, below .. So I declare both winners ! Thanks. All power corrupts, but we need electricity.	[reply]
