Hi. this piece work fine, but when a field occupies more than one line jump. Ej. the field AKA jump and no store the Year

Content .txt info is:
Original title
Yang Jia Jiang
AKA
Duong Gia Tuong
Saving General Yang
Year
2016

while let (Some(key), Some(value)) = (lines.next(), lines.next()) {
  if key.contains("Original Title"){
      original_title = value;
  } else if key.contains("AKA") {
      aka = value;
  } else if key.contains("Year") {
      year = value;
  }
}

Any suggestion ? Thanks

Any idea like this:

 while let (Some(key) = (lines.next()) {
                        if key.contains("Original title"){
                            lines.next();
                            original_title = key;
                        } else if key.contains("AKA") {
                            lines.next();
                            aka = key;
                        } else if key.contains("Year") {
                            lines.next();
                            year = key;
                        }
                    }

You can call lines.next() inside the loop.

while let (Some(key), Some(value)) = (lines.next(), lines.next()) {
  if key.contains("Original Title"){
      original_title = value;
  } else if key.contains("AKA") {
      aka = value;
      // ignore the next line
      let _ = lines.next();
  } else if key.contains("Year") {
      year = value;
  }
}

aka: Di Renjie: Shen du long wang

Not work in, more than two aliases. in field AKA

Had to grab the example code from one of your previous topics, but here is a playground link with a snippet showing how I would extend the code to make it work with multiple AKAs where we would skip all but the first AKA and only store that. Hope that helps.

Thanks.
solution for now. :woozy_face:

                    for line in lines {
                        if line.contains("Original title") {
                            original_title = find(&reader, &line).unwrap().trim();
                        } else if line.contains("AKA") {
                            aka = find(&reader, &line).unwrap().trim();
                        } else if line.contains("Year") {
                            year = find(&reader, &line).unwrap().trim();
                        }

                    }
