Hello, @isaac-goh, @peterjones and All,

Ah OK ! So, now, we have to find out something less restrictive, because :

The articles may contain digits or an underscore in their name
The quantities may contain the symbol :

In order that the regexes clearly recognize these two entities, I assume that the articles will always begin with an upper or lower letter !

So, from this INPUT text :

Orange123
50:00
20:00
apple234
30:00
20:00
10:00
pear456
50:00
20:00
21:00
10:00

The first regex S/R to use becomes :

SEARCH ^([\u\l]\w*\R)((?:[\d:]+(?:\R|(\Z)))+)
REPLACE $2(?3\r\n)$1 or $2(?3\n)$1 if you use Unix files

and gives :

50:00
20:00
Orange123
30:00
20:00
10:00
apple234
50:00
20:00
21:00
10:00
pear456

Then, the second regex S/R to use becomes :

SEARCH ^([\d:]+\R)(?=(?s:.*?)([\u\l]\w*)$)|^[\u\l]\w*\R
REPLACE ?1$2\x20$1

and gives the expected OUTPUT text :

Orange123 50:00
Orange123 20:00
apple234 30:00
apple234 20:00
apple234 10:00
pear456 50:00
pear456 20:00
pear456 21:00
pear456 10:00

Jut tell me if additional symbols must appear, apart from the : character, in the quantities !

Best Regards,

Yes additional symbols like underscore _ and additional colon : as shown below. Many thanks.

@Isaac-Goh ,

So what is the rule you use to decide which is the “header” line and which is the “other” lines? Is the rule “if it starts with a letter (uppercase or lowercase), it is a header line; if it starts with a number, it is an ‘other’ line”? Or something else.

You keep on changing what you expect. If you do not give a reasonable definition of what you want, you cannot expect that someone would get it right for you.

Hi, @isaac-goh, @peterjones and All,

Well. So :

The articles contain letters, may contain digits or an underscore in their name and begin with a letter
The quantities contains digits, may contain the : symbol and may have a trailing lower-case letter

In this case, use successively these two regex S/R, below :

SEARCH ^([\u\l]\w*\R)((?:[\d:]+\l?(?:\R|(\Z)))+)
REPLACE $2(?3\r\n)$1 or $2(?3\n)$1 if you use Unix files

and :

SEARCH ^([\d:]+\l?\R)(?=(?s:.*?)^([\u\l]\w*)$)|^[\u\l]\w*\R
REPLACE ?1$2\x20$1

Which will change the INPUT test :

Orange123_432
50:00:00:1e
20:00:00:1e
apple234_678
30:00:00:1a
20:00:00:1a
10:00:00:1a
pear456_321
50:00:00:1b
20:00:00:1b
21:00:00:1b
10:00:00:1b

into the expected OUTPUT text :

Orange123_432 50:00:00:1e
Orange123_432 20:00:00:1e
apple234_678 30:00:00:1a

Apology for my late reply as I am out of town for almost a week and need to scan thru more than 3000+ lines. This is what I have gathered as the possible longest lines.

@Isaac-Goh

So this isn’t a “data conversion service”.
The way it works is you get a couple of “freebies” and then that stops and you are expected to learn from what you have been given.
Of course you may ask questions about any small points, but in general you are expected to do your own work.
Also you may show what you’ve tried and explain how it wasn’t successful and ask for hints, but you may no longer ask for full solutions.

guy038

Hi, @isaac-goh, @peterjones, @alan-kilborn and All,

Of course, @alan-kilborn’s comments are pertinent and you should investigate a bit in regexes : refer to the USEFUL REFERENCES part at the end of the first post of @peterjones !

Now, out of curiosity, I wanted to know, why you asked me, again. Seemingly, my provided regexes did not match all your cases !

Oh…, everything is clear, now ! Really, @isaac-goh, you should have told me, from the very beginning that :

The header lines are a range of word characters \w, so digits, letters, whatever its case or underscore )
Each subsequent line is a range of hexadcimal digits [[:xdigit:]], separated with a colon char

This completly change the regexes, of course !

So from this INPUT text :

hq12orange1_HBA0_Max_123_PG1_FA1D30
21:00:00:0b:1f:c1:f6:ee
50:00:09:1a:50:06:1b:1f
10:00:00:10:ca:b1:60:94
H600_654342_3B_hq11apple6_HBA4
50:06:0b:50:12:45:fa:20
21:00:12:40:0d:c2:4b:75
VICTOR_200_BE_E3A1BC00_MAX_123_FA1D1
50:00:15:42:c1:32:21:1a
50:00:19:45:d1:06:14:04

with this first regex S/R :

SEARCH ^(\w+\R)((?:[[:xdigit:]:]+(?:\R|(\Z)))+)
REPLACE $2(?3\r\n)$1 or $2(?3\n)$1 if you use Unix files

It’ll gives you this text :

21:00:00:0b:1f:c1:f6:ee
50:00:09:1a:50:06:1b:1f
10:00:00:10:ca:b1:60:94

50:00:19:45:d1:06:14:04
VICTOR_200_BE_E3A1BC00_MAX_123_FA1D1

Then, with the second regex S/R, below :

SEARCH ^([[:xdigit:]:]+\R)(?=(?s:.*?)^(\w+)$)|^\w+\R
REPLACE ?1$2\x20$1

You’ll get the expected OUTPUT text :

hq12orange1_HBA0_Max_123_PG1_FA1D30 21:00:00:0b:1f:c1:f6:ee
