How to remove backslash , \n , " characters from given line

San

Hello,

I am reading a file and looking for a line as follows :

myFile=infile("/sample/file.txt")

while(gets(line myFile)

     if(rexMatchp("IPTECH" line) then myLine=line)

output is :

"INCLUDE \"$IPTECH/123/calibre_lvs/deckfile.txt\"\n"  

Now I just want

"$IPTECH/123/calibre_lvs/deckfile.txt"  

I tried different functions for rexMatchp , rexReplace etc but no success.

Please guide me through this.

Thanks

Sanket

    If you're using IC61X I'd recommend using the PCRE functions:

    pattern=pcreCompile("^[^\"]*\"([^\"]*)\"")
    pcreExecute(pattern line) => t

    pcreSubstitute(pattern "\\1") => 
    "$IPTECH/123/calibre_lvs/deckfile.txt"

    If you are using IC5141 you'd have to use rex functions instead (which are more limited).

    rexCompile("^[^\"]*\"\\([^\"]*\\)\"")
    rexExecute(line) => t
    rexSubstitute("\\1") =>
    "$IPTECH/123/calibre_lvs/deckfile.txt"

    Note that the pattern for rexCompile is slightly different - the grouping parentheses have to be escaped (hence the double backslash before them).

    A textual description of the pattern is beginning of the line (^) followed by any number of characters other than quote ([^\"]*), followed by a quote, followed by a group (surrounded by parentheses) which is any number of characters other than quote - followed by another quote.

    The \\1 in the "Substitute" function recalls the matched pattern in the first group.

    Regards,

    Andrew.
