The Java HTML API assists developers to write, read, modify, navigate and convert (X)HTML documents from within Java applications.

Aspose.HTML for Java API works as a headless browser that allows you to create or open existing HTML documents from various sources in order to perform manipulation operations such as remove and replace HTML nodes, save HTML documents, extract CSS from HTML, configure a document sandbox and more. You may navigate HTML documents by using various methods, such as, element traversal, document traversal, XPath queries, and CSS selector queries as well as manipulate HTML DOM via JavaScript, convert HTML file to images or fixed layout formats, and convert XHTML and EPUB files to other file formats.

Get Started

Aspose.HTML Java APIs are hosted at the Aspose Repository. You can easily use Aspose.HTML for Java API directly in your Maven projects with simple configurations. For the detailed instructions please visit Installing Aspose.HTML for Java from Aspose Repository documentation page.

Load HTML from a Remote Location

HTMLDocument document = HTMLDocument(new Url("template.html"));
// read children nodes and get length information
if (document.getBody().getChildNodes().getLength() == 0)
    System.out.println("No ChildNodes found...");
// print Document URI to console. As per information above, it has to be https://www.w3.org/TR/html5/
System.out.println("Print Document URI = " + document.getDocumentURI());
// print domain name for remote HTML
System.out.println("Domain Name = " + document.getDomain());
