Render HTML as fixed-layout formats - Java

// load the file to be rendered
HTMLDocument html = new HTMLDocument(dir + "template.html");
// render to PDF & XPS
HtmlRenderer renderer = new HtmlRenderer();
renderer.render(new PdfDevice(new PdfRenderingOptions(), dir + "output.pdf"), html);
renderer.render(new XpsDevice(new XpsRenderingOptions(), dir + "output.xps"), html);

The conversion process is highly customizable, allowing you to configure PageSetup aspects for the resultant fixed-layout formats, that is; you can specify the page numbers to be rendered, tweak the resultant page size or set the JPEG compression for the embedded images.

Extract all nodes of type anchor - Java

HTMLDocument document = new HTMLDocument("https://www.aspose.com");
// get all nodes of type anchor
NodeList nodelist = document.getDocumentElement().querySelectorAll("a");
// display anchor text & href values for all nodes
for (Node node : nodelist)
{
    HTMLAnchorElement anchor = (HTMLAnchorElement)node;
    System.out.println("Text: " + node.getTextContent() + " Href: " + anchor.getHref());
}
