Answer 1

Try this regex:

([az ]+?)\\s+(\\d+)\\s+([az]+)\\s+([\\d-\\/]+)\\s+([\\w ]+)

Explanation:

• ([az ]+?) - match 1+ occurrences(as few as possible) of a letter or a space and capture it as Group1
• \\s+ - matches 1+ occurrences of a whitespace character
• (\\d+) - match 1+ occurrences of digits and capture as Group2
• \\s+ - matches 1+ occurrences of a whitespace character
• ([az]+) - match 1+ occurrences of a letter and Capture as Group 3
• \\s+ - matches 1+ occurrences of a whitespace character
• ([\\d-\\/]+) - match 1+ occurrences of a digit or - or / and capture it as Group4
• \\s+ - matches 1+ occurrences of a whitespace character
• ([\\w ]+) - match 1+ occurrences of a word-character or a space and capture as Group5

Note that I have used the g , i , m flags for Global matches, Case-insensitive and Multiline respectively.
