@jishnupnair1996 Whats the result you need from above text file?

[quote=“jishnupnair1996, post:3, topic:95057”]

11,979.0\r\n0\r\n165.00 12,144.00 599.00 0.00 0.00 12,743.00

(?<=Grand Total)(.*?\n*?)(?=Original|1\.\s{0,1}Air)

Sorry this is the code

@jishnupnair1996 after “original” there is no “Air” word in your text.

some pdf files it may come
thats why i put it as an option

@jishnupnair1996 Try below Regex.

“(?<=Grand Total)(.?\n?)(?=Original(|1.)?\s?(Air)?)”


Sorry it wont work.

output is like this



Use .Groups to get the output.


RPO(0).Groups(1).Value.tostring (where RPO is your vairable and 0 is it’s index and 1 is the group number)

Hi @jishnupnair1996,

Please assign, string str= System.Text.RegularExpressions.Regex.Match(your_string,"((?<=Grand Total)[\s\S]+?(?=Original))").ToString.Replace("\r\n"," ")


Hi @jishnupnair1996,

If you want to extract the text between “Grand Total” and “Air” , if the string “Original” is not present, please assign str = System.Text.RegularExpressions.Regex.Match(str,"(?<=Grand Total)[\s\S]+?((?=Original)|(?=(1.\sAir)))").ToString.Replace("\r\n"," ")

Warm regards,

@jishnupnair1996 I checked same regex with your input and it is giving correct output.

Thanks @nimin
it worked well…

can you please explain the regex code also. it may help me to study more about regex

sorry it is not working in my case

Hi @jishnupnair1996,

(?<=Grand Total)[\s\S]+?((?=Original)|(?=(1.\sAir)))

(?<=xxx) and (?=xxx) are look behind and look ahead tokens, which searches for patterns after (?<=xxx) and before (?=xxx) without including the string ‘xxx’ in the result.
In between those strings, we need to capture everything. If we use .* it will skip line break. so [\s\S]+ helps to capture one or more occurrence of any white space characters(\s including [\r\n\t\f\v ]) and any non whitespace characters(\S) in the result. "|" operator acts as a logical OR condition.
I hope you got it now.:slightly_smiling_face:

Warm regards,
