InDesign GREP Help Two...

If you want to apply the character style to all link sources that are not page items, it's easy:

cstyle = app.documents[0].characterStyles.item ('myStyle');
sources = app.documents[0].hyperlinkTextSources.everyItem().getElements();
for (i = sources.length-1; i >= 0; i--) {
  s[i].appliedCharacterStyle = cstyle;
}

because it targets all hyperlink text sources. But if it should be restricted to e.g. URL sources, it gets more complicated.

LOL Peter: you beat me by 7 seconds! 😂

Hi @JonathanJacqu28834810rfuu:

InDesign can do that for you without GREP as you add your URLs.

You don't need any Grep. When you create a hyperlink you can set a character style in the interface: 

And when you create a hyperlink in a script, you can apply a character style when you create the hyperlink source.
