detect certain letters in the first row of a text layer

[Filip Vandueren]

Hi Detlef, here’s a method using regular expressions.

I suppose that with the first Row, you mean the first line that is explicitly ended by a line-break, not a line that is automatically wrapped by a textbox ?

firstline = thisComp.layer("txt").text.sourceText.split("\r")[0];
booleanResult = /Ä|Ö|Ü/.test(firstline);

Yes, that’s what I meant. Works perfectly! Thank you very much! One additional question: what should the syntax look like for the last line?

[Filip Vandueren]

something like this:

lines = thisComp.layer("txt").text.sourceText.split("\r");
firstline = lines[0];
lastline = lines[lines.length-1];
booleanResult = /Ä|Ö|Ü/.test(lastline);
