Search for a string in Data Merge, then change the font color

Question

I'm working on a postcard-style invitation with the addresses on the back. So far, I've finished the invitation and the mail-side template with a Data Merge to a CSV file successfully. Now, as part of my design, I want all of the letter "b"s on the mail-side template (Data Merge) to be yellow. Using JavaScript is this possilbe? This is what I have so far, but something is wrong:
     app.findTextPrefences = NothingEnum.NOTHING as FindTextPreference;
     app.changeTextPrefences = NothingEnum.NOTHING as ChangeTextPreference;
     var myColor:Color = myDocument.colors.add();
     myColor.model = ColorModel.PROCESS;
     myColor.space = ColorSpace.CMYK;
     myColor.colorValue = [0, 0, 100, 16];
     app.findChangeTextOptions.caseSensitive = false;
     app.findChangeTextOptions.includeFootnotes = false;
     app.findChangeTextOptions.includeHiddenLayers = false;
     app.findChangeTextOptions.includeLockedLayersForFind = false;
     app.findChangeTextOptions.includeLockedStoriesForFind = false;
     app.findChangeTextOptions.includeMasterPages = false;
     app.findChangeTextOptions.wholeWord = false;
     app.findTextPrefences.findWhat = "b";
     app.changeTextPrefences.fillColor = myColor;
     app.findTextPrefences = NothingEnum.NOTHING as FindTextPreference;
     app.changeTextPrefences = NothingEnum.NOTHING as ChangeTextPreference;

Answer 1

Hi,
After setting preferences you need to call changeText() method, like
myDoc.changeText();
or
myStory.changeText();
But this is a static solution.
You could use a dinamic solution by define a proper characterStyle and take advantage of nestedGrepStyle in style applied to this part of your design.
So each character "b" could be applied with your characterStyle automatically, no need to run a script.
