Converting Specific Data Segments from a .dat File to CSV Format with Timestamps

I have a .dat file containing data segments structured in a format similar to the one below:

This dataset contains multiple segments similar to the provided snippet, each representing a 10-minute interval of records between each $.$

I need assistance in converting this data into a CSV file named 'output.csv' with a specific format:

1. The first row contains headers specified as below.
2. Subsequent rows should contain:

• Timestamp in YYYY-MM-DD HH:MM:SS format extracted from the XML.
• Wind speeds at different altitudes (200m to 30m).
• Wind directions at different altitudes (200m to 30m).

For example, for a given input, the desired output CSV would resemble:

Timestamp, ALT200_Speed, ALT190_Speed, ..., ALT30_Speed, ALT200_Dir, ALT190_Dir, ..., ALT30_Dir2023-12-07 00:00:00, 299, 288, ..., 29, 46, 46, ..., 732023-12-07 00:00:10, 598, 599, ..., 591, 39, 39, ..., 36

I seek guidance or a code solution in Python or any other suitable language to efficiently process this large dataset and generate the desired output CSV containing the specified information.

Read .dat file and extract relevant data segments

Loop through the file, identify and extract segments containing wind data between $ symbol

Process each segment to extract timestamps, wind speeds, and directions

Generate 'output.csv' with appropriate headers and write data

Write each timestamp, wind speeds, and directions to the CSV file in the specified format
