Named after the fish: Zander. It's a small library to ease with parsing structured blocks of information within a 2-dimensional matrix of information. Typically you get this sort of information from report generators. You might still want to extract this information programmatically, thus the need for the fish.

When you have data in a structured format, but with different blocks of information. A very simple example is the following:

But the structure of the block layout might change from "page" to "page".

• Use _ to indicate that there should be an empty column
• Use "Some constant" or constant to indicate a column with a constant value
• Use @Value to indicate that you want the value on that column
• Use ( .. | .. ) to match any of

In order to match rows you supply the row specification with a name by postfixing with : title If you want the row to match many rows with the same format you add a '+' : : title+

How do you use this library to extract the information above? You use the parser builder:

using Zander;
...
 var parsed = new BlockEx( @" _          _ _ _ _ _ ""Report Title"" _  _  _  @Time @Page : report_title
                                ""Company AB"" _ _ _ _ _ _                _ _ _ _  _          : company
                                    @Text      _ _ _ _ _ _                _ _ _ _  _          : text+
                                  _         Id _  Value  Type _ _ ""Attribute 1"" _ ""Attribute 2"" _  _ : header
                                  _        @Id _ @Value @Type _ _ (@Attribute1|_) _ (@Attribute2|_) _  _ : row+
                    ")
                .Matches(arrayOfArrays);

This will give you structured information that will be easy to consume.
