Developers can customize by configuring PageSetup aspects for the resultant fixed-layout formats including page numbers to be rendered, resultant page size or setting the JPEG compression for the embedded images.

Render HTML as fixed-layout formats - Java

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

Manipulation of ePub and MHTML Files

The library is capable of loading ePub and MHTML files to perform various operations including the conversion to fixed-layout and raster image formats.

HTML Nodes Navigation

API supports navigation through the HTML file either by XPath,  elements or CSS selector queries and one can insert, extract, remove or replace nodes easily.

Extract all nodes of type anchor - Java

// instance creation of HTMLDocument and loading HTML from URL
HTMLDocument dct = new HTMLDocument("https://www.aspose.com");
// get all anchor type nodes 
NodeList nodelist = dct.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());
