Extract metadata from EPUB eBook
To extract metadata from EPUB e-books GetMetadata method is used. This method allows to extract the following metadata:
| Name | Description |
|---|---|
| title | The title of the e-book. |
| subject | The subject of the e-book. |
| author | The name of the e-book’s author. |
| language | The language of the e-book. |
| published-date | The published date of the e-book. |
| description | The description of the e-book. |
| publisher | The publisher of the e-book. |
| copyrights | The copyrights of the e-book. |
Here are the steps to extract metadata from EPUB e-book:
- Instantiate Parser object for the initial e-book;
- Call GetMetadata method and obtain collection of document metadata objects;
- Iterate through the collection and get metadata names and values.
GetMetadata method returns null value if metadata extraction isn’t supported for the document. For example, metadata extraction isn’t supported for Zip archive. Therefore, for Zip archive GetMetadata method returns null. If EPUB e-book has no metadata, GetMetadata method returns an empty collection.
The following example demonstrates how to extract metadata from EPUB e-book:
// Create an instance of Parser class
using(Parser parser = new Parser(filePath))
{
// Extract metadata from the e-book
IEnumerable<MetadataItem> metadata = parser.GetMetadata();
// Iterate over metadata items
foreach(MetadataItem item in metadata)
{
// Print the item name and value
Console.WriteLine(string.Format("{0}: {1}", item.Name, item.Value));
}
}
