Extract formatted text from document page Leave feedback
GroupDocs.Parser provides the functionality to extract a formatted text from document page by the getFormattedText(int, FormattedTextOptions) method:
TextReader getFormattedText(int pageIndex, FormattedTextOptions options);
The method returns an instance of TextReader class with an 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. |
TextReader class extends java.io.Reader and adds the following members:
| Member | Description |
|---|---|
| readLine | Reads a line of characters from the text reader and returns the data as a string. |
| readToEnd | Reads all characters from the current position to the end of the text reader and returns them as one string. |
Here are the steps to extract a HTML formatted page text from the document:
- Instantiate Parser object for the initial document;
- Instantiate FormattedTextOptions with HTML text mode;
- Call getFormattedText(int, FormattedTextOptions) method with the page index and obtain TextReader object;
- Check if reader isn’t null (formatted text extraction is supported for the document);
- 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
try (Parser parser = new Parser(Constants.SampleDocx)) {
// Check if the document supports formatted text extraction
if (!parser.getFeatures().isFormattedText()) {
System.out.println("Document isn't supports formatted text extraction.");
return;
}
// Get the document info
IDocumentInfo documentInfo = parser.getDocumentInfo();
// Check if the document has pages
if (documentInfo.getPageCount() == 0) {
System.out.println("Document hasn't pages.");
return;
}
// Iterate over pages
for (int p = 0; p < documentInfo.getPageCount(); p++) {
// Print a page number
System.out.println(String.format("Page %d/%d", p + 1, documentInfo.getPageCount()));
// Extract a formatted text into the reader
try (TextReader reader = parser.getFormattedText(p, new FormattedTextOptions(FormattedTextMode.Markdown))) {
// Print a formatted text from the document
// We ignore null-checking as we have checked formatted text extraction feature support earlier
System.out.println(reader.readToEnd());
}
}
}
