Select data on a partcular basis and check for errors

Hi all,

In my project i have to split a string from a text on a basis and check for error existence…

NB: The text data shown here is a table extracted from pdf in the form of text.

The Text is

SAC Code Taxable\r\nValue\r\nNonTaxable\r\n/Exempted\r\nValue\r\nTotal\r\nIGST\r\nTax % Amount\r\nCGST\r\nTax % Amount\r\nSGST/UGST\r\nTax % Amount\r\nTotal(Incl\r\nTaxes)\r\nAir Travel and related charges 996425 4,790.00 0.00 4,790.00 0.00 0.00 2.50 119.75 2.50 119.75 5,029.50\r\nMeal 996425 212.00 0.00 212.00 0.00 0.00 9.00 19.08 9.00 19.08 250.16\r\nAirport Charges 0.00 236.00 236.00 0.00 0.00 0.00 0.00 0.00 0.00 236.00\r\n:

From this text i want to split the string of numbers starts after “Air Travel and related charges” and ends with the next newline (\r\n).
Then i have to check that whether the elements after newline is alphabets (A-Z/a-z);
if it is alphabets
then check that if there is any alphabets present inside the selected string
Else
then split the string on the next newline.

The Splited string should be like this:
“996425 4,790.00 0.00 4,790.00 0.00 0.00 2.50 119.75 2.50 119.75 5,029.50”
