Extract formatted text from document page Leave feedback
GroupDocs.Parser provides the functionality to extract formatted text from document page by the GetFormattedText(int, FormattedTextOptions) method:
TextReader GetFormattedText(int pageIndex, FormattedTextOptions options);
Methods return an instance of TextReader class with the extracted text. FormattedTextOptions has the following constructor:
FormattedTextOptions(FormattedTextMode mode);
FormattedTextMode enumeration has the following members:
| Member | Description |
|---|---|
| Html | Html format. |
| Markdown | Markdown format. |
| PlainText | Plain text format. |
Here are the steps to extract a HTML formatted page text from the document:
- Instantiate Parser object for the initial document;
- Check if formatted text extraction is supported for the document;
- Instantiate FormattedTextOptions with HTML text mode;
- Call GetFormattedText(int, FormattedTextOptions) method with the page index and obtain TextReader object;
- Read a text from reader.
The following example shows how to extract a document page text as Markdown text:
// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
// Check if the document supports formatted text extraction
if (!parser.Features.FormattedText)
{
Console.WriteLine("Document isn't supports formatted text extraction.");
return;
}
// Get the document info
IDocumentInfo documentInfo = parser.GetDocumentInfo();
// Check if the document has pages
if (documentInfo.PageCount == 0)
{
Console.WriteLine("Document hasn't pages.");
return;
}
// Iterate over pages
for (int p = 0; p < documentInfo.PageCount; p++)
{
// Print a page number
Console.WriteLine(string.Format("Page {0}/{1}", p + 1, documentInfo.PageCount));
// Extract a formatted text into the reader
using (TextReader reader = parser.GetFormattedText(p, new FormattedTextOptions(FormattedTextMode.Html)))
{
// Print a formatted text from the document
// We ignore null-checking as we have checked formatted text extraction feature support earlier
Console.WriteLine(reader.ReadToEnd());
}
}
}
