Re: Regex replacement item for entire line?

[David Rostenne]

Hi Roland,

The solutions proposed all work.. but they require that the regex pattern 
matches the entire line first. i was being lazy and hoping for a way to grab 
the entire line without matching it first.

Cheers,

Dave

Re: Regex replacement item for entire line?

[Roland Küffner]

Hi,
Bruce Van Allen has alredady provided a solution - so, just out of
curiosity: I was wondering why you were searching for a replacement for the
"&" in the replacement string? It does exactly what you want and it is a
single character. It's hard to get that simpler or more elegant. But maybe
I'm missing a thought.

Surround the whole pattern with parentheses. That will then be 
the capture contained in \1. You will then have to increment 
each other capture by 1.


Original:
http://ftp.newedinburgh.ca/wp-content/uploads/2019/09/1976_04-April-New-Edinburgh-News_web.pdf

Pattern:
(.+?/2019/[019]+/([0-9]+)[_.]([0-9]+)-([a-zA-Z]+).*\n)

Replacement:
\4 \2, NEN PDF, \2/\3/01, \1

Result:
April 1976, NEN PDF, 1976/04/01, 
http://ftp.newedinburgh.ca/wp-content/uploads/2019/09/1976_04-April-New-Edinburgh-News_web.pdf

Note that the above pattern includes the end of line ("\n"); if 
you don't want that, move the closing parenthesis to before the "\n".

Re: Regex replacement item for entire line?

[ThePorgie]

I was looking at this again and I think I now understand what you're asking 
forYou don't want to have to write the regex to find the text before 
what you're wanting to put into your delimited result, but you also would 
like it to put the result in front of the whole string. Have I got that 
right? If so, I don't think you can do that with a regex...err, should I 
say "I certainly don't know how to pull that one off".

I was hoping for an alternative to the & in the replacement strung that means

Re: Regex replacement item for entire line?

[ThePorgie]

Would something like this be what you're looking for?

.+?/2019/[019]+/([0-9]+)[_.]([0-9]+)-([a-zA-Z]+).* 

This will give you the same result with your replacement string.

\3 \1, NEN PDF, \1/\2/01, & 

The ".+?" tells the expression to find everything till the rest of the 
expression that remains matches. If anything is off in the rest of the 
expression it won't find a result in the string being searched.

Is that what you're looking for?

Re: Regex replacement item for entire line?

[Kerri Hicks]

If the URL is always exactly the same up to the point of the date that
you're capturing now (as it appears it must be for the expression to
match), you could create a capture group of the first 51 characters
(assuming I counted them right), and then use a backreference to that. I'm
not sure that would be better in any way, but it would be a shorter regex.

Regex replacement item for entire line?

[David Rostenne]

Hi folks,

I have a regex that takes a url apart and makes me a csv of the components:

Regex:
http://ftp\.newedinburgh\.ca/wp-content/uploads/2019/[019]+/([0-9]+)[_.]([0-9]+)-([a-zA-Z]+).*

and the replacement:
\3 \1, NEN PDF, \1/\2/01, &

which gives, for example:
April 1976, NEN PDF, 1976/04/01, 
http://ftp.newedinburgh.ca/wp-content/uploads/2019/09/1976_04-April-New-Edinburgh-News_web.pdf

I am wondering if there is a way to leave the http…2019 out of the regex and, 
instead of the & (which matches entire regex selection) in the replacement, use 
something else to represent the entire source line.

As you can see i’ve found a solution.. but I am always curious to see if there 
is a simpler way.

Cheers,

Dave
