    for (int i = 0; i < variables.length; i++) {
        // look if Javadoc tags have to be added
        TemplateVariable position = findVariable(buffer, variables[i]);
        if (position == null || position.getLength() > 0) {
            continue;
        }
        int[] offsets = position.getOffsets();
        for (int k = 0; k < offsets.length; k++) {

            IRegion lineInfo = doc.getLineInformation(line);
            int offset = lineInfo.getOffset();
            String str = doc.get(offset, lineInfo.getLength());
            if (Strings.containsOnlyWhitespaces(str) && nLines > line + 1 && removedLines.add(new Integer(line))) {
                int nextStart = doc.getLineOffset(line + 1);
                edit.addChild(new DeleteEdit(offset, nextStart - offset));
            }
        }
    }
    edit.apply(doc, 0);
    return doc.get();
}
