String manipulation question

CADcasualty
CADcasualty over 6 years ago

I have a procedure that returned a string into a variable named myString:

myString="abc\\ndef"

I want to take myString and scan for the "\\n" part and change it to "\n" and copy the result into myNewString so that I end up with:

myNewString = "abc\ndef"

The intent here is to print myNewString and have it appear as 2 lines of text ("abc" and "def") - I'm sure this is simple, but for the life of me I can't figure it out :-(.

    Hi,

    The second item is easy enough but I haven't got time to wrestle with the first - you will most likely need "\\\\" to find the "\\" pattern, and then need some substitution, both of these using the pcre* functions.

    parseString(myNewString "\n")
    => ("abc" "def")

    Best regards,

    Lawrence.

    Hi,

    Can you try this one:

    (pcreExecute (pcreCompile "(.*)\\\\n(.*)" ) myString)
    (pcreSubstitute "\\1\\2" )

    Or simpler, just do:

    badReturn=pcreCompile("\\\\n")
    myNewString=pcreReplace(badReturn myString "\n" 0)

    Regards,

    Andrew.

    Wow - thanks everybody! The pcre stuff solved my problem. I did try the parseString thing beforehand but it messed things up when the random text either side of the \n contained the character "n"
