Isolate first line of text using RegEx

@tlabelleacc,

It is not clear to me whether the so called clusters are in separate files or can be found within a file.

If it is the latter, I think I would first break up the text by searching for a dubble newline. This can be done using an AttributeSplitter and a ListExploder.

Second, when I look at the texts that are marked bold, I see no white spaces or other similar characters. So you could use a RegEx syntax like ^(.*)?\\s to get the first line or, if you don't want to use RegEx, just repeat the previous step and search for a single newline character and put the first list item in a new attribute. That would probably do the trick as well.

Though I'm not @Takashi, I can only wish to become a grandmaster like him, I do hope it helps you forward.

The AttributeSplitter would create over 6000+ lists as my text file has over 3000 clusters...Unfortunately the RegEx did not return anything through the RegAttributeSplitter?

Can you provide a sample of the text file itself? My first thought would be to read the text file line by line and use adjacent attribute handling to isolate the lines you want.

If the first line always starts with 'WGS84-' and other lines don't, simply you can use a Tester with the "Begins With" operator to isolate the first line.
