Extract hyperlinks from document page Leave feedback
GroupDocs.Parser provides the functionality to extract hyperlinks from document page by the getHyperlinks(int) method:
Iterable<PageHyperlinkArea> getHyperlinks(int pageIndex);
This method returns a collection of PageHyperlinkArea object:
| Member | Description |
|---|---|
| getPage | The page that contains the text area. |
| getRectangle | The rectangular area on the page that contains the text area. |
| getText | The hyperlink text. |
| getUrl | The hyperlink URL. |
Here are the steps to extract hyperlinks from the document page:
- Instantiate Parser object for the initial document;
- Check if the document supports hyperlink extraction;
- Call getHyperlinks(int) method with the page index and obtain collection of PageHyperlinkArea objects;
- Iterate through the collection and get a hyperlink text and URL.
The following example shows how to extract hyperlinks from the document page:
// Create an instance of Parser class
try (Parser parser = new Parser(Constants.HyperlinksPdf)) {
// Check if the document supports hyperlink extraction
if (!parser.getFeatures().isHyperlinks()) {
System.out.println("Document isn't supports hyperlink 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 pageIndex = 0; pageIndex < documentInfo.getPageCount(); pageIndex++) {
// Print a page number
System.out.println(String.format("Page %d/%d", pageIndex + 1, documentInfo.getPageCount()));
// Extract hyperlinks from the document page
Iterable<PageHyperlinkArea> hyperlinks = parser.getHyperlinks(pageIndex);
// Iterate over hyperlinks
for (PageHyperlinkArea h : hyperlinks) {
// Print the hyperlink text
System.out.println(h.getText());
// Print the hyperlink URL
System.out.println(h.getUrl());
System.out.println();
}
}
}
