    I have a one file and it looks like this.
    |OldCname|NewCname|OldADD|NewADD|OldPhone|newPhone|
    |A|A|123|124|5551212|55151212|

    --This is an example. The first row has the names of the columns.
    -- all rows after have data. All COLUMNS are seperated by the same seperation character. here it is the -> |
    if you count the (( # of '|' )-1)/2 you get 3 which is how many compares for each row.
    I want to compare each pair. The columns are of varying length. This is why I am using the seperator ( old|new) .
    I would like an an output file that spells out each difference for each line. No output for matches.
    For example in the output file.
    I would see
    Line 1: OldCname -> 123, NewCname -> 124
    Line 1: OldPhone -> 5551212, NewPhone -> 5511212
    ...... for any non matched pair on a line.


    and so on for each line that do not have a match for any pair. The number of old/new pairs can be long and is variable, but always in pair groups.
    The three variables I see are the
    Seperator, number of pairs and the output file to store the diff info.

    Any help would be appreciated.

      Here is the simple script which should do the task quickly.

      Code: Select all

      if (UltraEdit.document.length > 0) {   // Is any file currently opened?
      
         // Define the environment for the script.
         UltraEdit.insertMode();
         UltraEdit.columnModeOff();
      
         // Select entire file content.
         UltraEdit.activeDocument.selectAll();
         if (UltraEdit.activeDocument.isSel()) {  // Is active file not an empty file?
      
            // Determine line termination.
            var sLineTerm = "\r\n";
            if (UltraEdit.activeDocument.lineTerminator == 1) sLineTerm = "\n";
            else if (UltraEdit.activeDocument.lineTerminator == 2) sLineTerm = "\r";
      
            // Get all lines into an array of strings.
            var asLines = UltraEdit.activeDocument.selection.split(sLineTerm);
            UltraEdit.activeDocument.top();       // Cancel the selection.
      
            var asHeaders = asLines[0].split("|");
            if (asHeaders != null) {
               // If last header string is an empty string because the
               // line ended with |, remove this string from the array.
               if (asHeaders[asHeaders.length-1].length == 0) asHeaders.pop();
               // Remove also the first string if it is an empty
               // string because the line started with separator |.
               if (asHeaders[0].length == 0) asHeaders.shift();
      
               // Remove the last line string if it is an empty string
               // because last line of active file has a line termination.
               if (asLines[asLines.length-1].length == 0) asLines.pop();
      
               // Use clipboard 9 for output data.
               UltraEdit.selectClipboard(9);
               UltraEdit.clearClipboard();
      
               // Process all data lines.
               for (var nLineNum = 1; nLineNum < asLines.length; nLineNum++) {
      
                  // Uncomment next line if empty lines could be present in file.
                  // if (asLines[nLineNum].length == 0) continue;
      
                  // Get the | separated elements of this line.
                  var asElements = asLines[nLineNum].split("|");
      
                  // Remove first and last string if empty strings.
                  if (asElements[asElements.length-1].length == 0) asElements.pop();
                  if (asElements[0].length == 0) asElements.shift();
      
                  // Compare the pairs of elements of current line.
                  for (var nElementNum = 0; nElementNum < asElements.length; nElementNum += 2) {
      
                     // Are the two strings identical (case sensitive), continue with next pair.
                     if (asElements[nElementNum] == asElements[nElementNum+1]) continue;
      
                     // The strings are different. Append the output to user clipboard 9.
                     UltraEdit.clipboardContent += "Line "+nLineNum+": "+asHeaders[nElementNum]+" -> "+asElements[nElementNum]+", "+
                                                   asHeaders[nElementNum+1]+" -> "+asElements[nElementNum+1]+"\r\n";
                  }
               }
               // Are not identical element strings found which should be output to a file?
               if (UltraEdit.clipboardContent.length) {
                  UltraEdit.newFile();
                  // Make sure that line terminator type is DOS as the lines in clipboard.
                  UltraEdit.activeDocument.unixMacToDos();
                  UltraEdit.activeDocument.paste();
                  UltraEdit.activeDocument.top();
                  UltraEdit.clearClipboard();
               }
               else {
                  UltraEdit.messageBox("All pairs are identical!");
               }
               UltraEdit.selectClipboard(0);
            }
         }
      }
