How to Replace:Characters with Newline

How to replace a character by a newline in Vim

Use \r instead of \n.

Substituting by \n inserts a null character into the text. To get a newline, use \r. When searching for a newline, you’d still use \n, however. This asymmetry is due to the fact that \n and \r do slightly different things:

\n matches an end of line (newline), whereas \r matches a carriage return. On the other hand, in substitutions \n inserts a null character whereas \r inserts a newline (more precisely, it’s treated as the input CR). Here’s a small, non-interactive example to illustrate this, using the Vim command line feature (in other words, you can copy and paste the following into a terminal to run it). xxd shows a hexdump of the resulting file.

echo bar > test
(echo 'Before:'; xxd test) > output.txt
vim test '+s/b/\n/' '+s/a/\r/' +wq
(echo 'After:'; xxd test) >> output.txt
more output.txt

Before:
0000000: 6261 720a                                bar.
After:
0000000: 000a 720a                                ..r.

In other words, \n has inserted the byte 0x00 into the text; \r has inserted the byte 0x0a.

Replace newlines with literal \n

This should work with both LF or CR-LF line endings:

sed -E ':a;N;$!ba;s/\r{0,1}\n/\\n/g' file

Find and replace with a newline in Visual Studio Code

In the local searchbox (ctrl + f) you can insert newlines by pressing ctrl + enter.

If you use the global search (ctrl + shift + f) you can insert newlines by pressing shift + enter.

If you want to search for multilines by the character literal, remember to check the rightmost regex icon.

In previous versions of Visual Studio code this was difficult or impossible. Older versions require you to use the regex mode, older versions yet did not support newline search whatsoever.

Regex how to replace 'string' with a new line but keep the 'string'

\<([^>]*)\>

This regex will capture the text between < and > into a capture groups, which you can then reference again and put a newline between them.

\1\n

EDIT:

In PowerShell

PS C:\Users\shtabriz> $string = "<'sample text'><'sample text 2'>"
PS C:\Users\shtabriz> $regex = "\<([^>]*)\>"
PS C:\Users\shtabriz> [regex]::Replace($string, $regex, '$1'+"`n")
'sample text'
'sample text 2'

How to replace a new line character in Javascript?

"\n" is a newline character. You're replacing them with what's already there, leaving the String unchanged. If you want the actual characters \ and n, you need to mask the backslash \\n and insert that.

I don't have access to your pdf file, so I processed one on my system. I also don't know if you need to remove all new lines or just double new lines. The code below remove double new lines, which makes the output more readable.

Please let me know if this works for your current needs.

from tika import parser

filename = 'myfile.pdf'

# Parse the PDF
parsedPDF = parser.from_file(filename)

# Extract the text content from the parsed PDF
pdf = parsedPDF["content"]

# Convert double newlines into single newlines
pdf = pdf.replace('\n\n', '\n')

# Do something with the PDF

print (pdf)
