First of all I'd like to thank everyone that helps. I'm a complete beginner at scripting and appreciate all your help.
I'm basically using GREP expressions to find patterns in a document and apply a Character Style which has already been made. This Character style was not made using script, but just in InDesign when making and setting up the template.
var myDoc = app.activeDocument; //Clear the find/change grep preferences.
app.findGrepPreferences = NothingEnum.nothing;
app.changeGrepPreferences = NothingEnum.nothing; //Set the find options.
app.findChangeGrepOptions.includeFootnotes = false;
app.findChangeGrepOptions.includeHiddenLayers = false;
app.findChangeGrepOptions.includeLockedLayersForFind = false;
app.findChangeGrepOptions.includeLockedStoriesForFind = false;
app.findChangeGrepOptions.includeMasterPages = false; //GREP Expression for finding all HEADERS
app.findGrepPreferences.findWhat = ".+\n"; //Applying formatting changes to put into All Caps, Bold and changing the font size to 12 pt.
app.changeGrepPreferences.capitalization = Capitalization.allCaps;
app.changeGrepPreferences.fontStyle = "Bold";
app.changeGrepPreferences.pointSize = "12";
myDoc.changeGrep(); //Clear the find/change preferences after the search.
app.findGrepPreferences = NothingEnum.nothing;
app.changeGrepPreferences = NothingEnum.nothing;
This is how I currently have it. I will manually define the changes to the text. The problem is, each template uses a different set of fonts and not all of them use Bold e.g. Sabon can use CE Bold.
I would like to learn how to apply a Character Style and have tried looking around but nothing seems to work.
Any help would be much appreciated.
Thanks.
