Seemingly, Ty-Ty, you’re asking for three different points :

• A : How to delete some structured data, located at each beginning of line ?

• B : How to delete some structured data, located at each end of line ?

• C : How to add a string at each end of line ?

Just note that the points B and C may be replaced with :

• D : How to replace some structured data, at each end of line, by a literal string

So, let’s imagine your initial list, opened in Notepad++ :

  *363780  willtall@gmail.com:xenogears
  *363781  kaansoulp@gmail.com:kaan1976
  *363782 angelica.valila@gmail.com:pissis69 
  *363782 angelica.valila@gmail.com:pissis69
  *363784 twsnyderman@yahoo.com:sdchbltmvp
  *363785 shaunamiekley@gmail.com:lfhs929
  *363786 kynajo@gmail.com:jehovah1
  *363787 stynrynn@gmail.com:satya96
  *363788 haleyottley@gmail.com:haley0ttley
  *363789 pandemonium.jones@gmail.com:odder7471
  *363790 marielle_koudijs@hotmail.com:Larissa18
  *363791 robnoice@gmail.com:robtb303
  *363792 willtall@gmail.com:xenogears
  *363793 kaansoulp@gmail.com:kaan1976
  *363794 angelica.valila@gmail.com:pissis69
  *363795 megsellig@gmail.com:bhyc9999
  *363796 twsnyderman@yahoo.com:sdchbltmvp
  *363797 shaunamiekley@gmail.com:lfhs929
  *363798 kynajo@gmail.com:jehovah1
  *363799 stynrynn@gmail.com:satya96

Obviously, we can deduce that :

• The part to delete, at the beginning, of each line ( Case A ) :

  • Begin by possible space characters, followed by a * symbol

  • Then followed by some digits ( 6 in our example ) and ends with possible space characters

• The part to delete, at the end, of eech line ( Case B ) :

  • Begin with the unique colon of each line, followed by all the remaining characters of each line

So, to achieve point A :

• Open the Replace dialog ( Ctrl + H )

• Type in the regex ^\x20*\*\d+\x20*, in the Find what: zone

• Leave the Replace with: zone EMPTY

• Check the Wrap around and Regular expression options

• Click on the Replace All button

Notes :

• The ^ symbol means the beginning of line location

• Then, the syntax \x20* represents a string, possibly empty, of space characters

• The form \* try to match a literal star character. It must be escaped, due to its special meaning in regexes

• And \d+ stands for a non-empty range of consecutive digits

• Again, \x20* matches a string, possibly empty, of space characters, before each e-mail address

To achieve point B :

• Open the Replace dialog ( Ctrl + H )

• Type in the regex :.+, in the Find what: zone

• Leave the Replace with: zone EMPTY

• Check the Wrap around and Regular expression options

• Click on the Replace All button

Notes :

• First, the : matches a literal colon symbol

• Then the syntax .+ represents any non-empty range of characters, located after the colon, till the end of each line

But, you may combine all these search-replacements, in an unique regex

Therefore, to achieve points A and D, at the same time, use the regexes, below :

SEARCH ^\x20*\*\d+\x20*|(:.+)

REPLACE ?1\x20\x20\x20\x20\x20\x20Love

Notes :

• The search regex is just an alternative between the two regexes, discussed above

• The second regex (:.+) is surrounded by round parentheses, to be stored as group 1

• In replacement, the form ?1....... means :

  • If group 1 exists, just replace the colon and all text, located after, by six space characters, followed by Love

  • If group 1 does not exist, delete all text, before each e-mail address, as the ELSE part of this conditional replacement is absent !

So, after a click on the Replace All button, you should get the text below :

willtall@gmail.com      Love
kaansoulp@gmail.com      Love
angelica.valila@gmail.com      Love
angelica.valila@gmail.com      Love
twsnyderman@yahoo.com      Love
shaunamiekley@gmail.com      Love
kynajo@gmail.com      Love
stynrynn@gmail.com      Love
haleyottley@gmail.com      Love
pandemonium.jones@gmail.com      Love
marielle_koudijs@hotmail.com      Love
robnoice@gmail.com      Love
willtall@gmail.com      Love
kaansoulp@gmail.com      Love
angelica.valila@gmail.com      Love
megsellig@gmail.com      Love
twsnyderman@yahoo.com      Love
shaunamiekley@gmail.com      Love
kynajo@gmail.com      Love
stynrynn@gmail.com      Love

Remark : In the regexes, you may type a single space character, instead of the \x20 syntax ! But, that later form just suppresses any ambiguity !

Best Regards,

all solution would need regular expression to be checked and assume that the whole file
looks like your example.

let me start with the easiest first

find what:$
replace with: YOUR_TEXT

per default $ denotes the end marker of each line

next two’s will work until there are only VALID email addresses.
It won’t work if there is something like name space @ space domain.name

delete everything in front:

find what:(.+?)(?=\x20.+?@)
replace with:nothing - leave empty

?= is a lookahead which means you are searching for text only if it is
followed by a space(\x20) followed by anything (.+) but as less as possible (?) and a @

delete everything after the domain name

find what:@\<.+?\..+?\>\K.+
replace with:nothing - leave empty

The last one uses \K which means it only works if you press replace all.
Searching for @ next must start a word (\<) followed by anything as less as possible
followed by a dot (\.) literally followed by as less as possible but must end with a word.
\K ignores that it has matched anything so that the rest (.+) is the only one which gets reported
back as the match.

I know, not as detailed as guy038’s explanations but hopefully understandable.

Cheers
Claudia

   .......

I have a file as in the number of 5000 lines. My question is: How do I delete the numbers in front of each line for example :

  willtall@gmail.com:xenogears
  kaansoulp@gmail.com:kaan1976
  angelica.valila@gmail.com:pissis69 
 .....

If you want to delete the back of each line for example :

 *363780 willtall@gmail.com
 *363781 kaansoulp@gmail.com
 *363782 angelica.valila@gmail.com
  ......

And the last question: If I want to add at the back of each line for example:

*363780  willtall@gmail.com      Love ( Space is 6 times press Space )
*363781  kaansoulp@gmail.com      Love
*363782 angelica.valila@gmail.com      Love       
...... 

Seems like these are troublesome questions. I do not use these questions to assess your understanding. Exactly, I’m in a situation like this to solve. Looking forward to receiving your complete reply. Thank you

You want to use regular expression search and replace operations.

At the end of this post @guy038 points out where you can find information to help you do that.

You will have a lot more luck getting people interested in helping if you recreate part of your file here rather than how you described it. Just take part of your file and add four space to the start of each line and then paste it here. Then it will look like this and it will be much more understandable what you are starting with:

Of course you have to also describe what you want well, too. MAYBE you did that above, or maybe not (I find that my head hurts when I look at what you composed, so I can’t judge…)

actually I’m not sure if you want to delete the numbers or the xxxxx or both.
Provide some kind of before and after data, then it might me more clear.
