How To Convert A Jsoup Document To A W3c Document?

I have build a Jsoup Document by parsing a in-house HTML page, public Document newDocument(String path) throws IOException { Document doc = null; doc = Jsoup.connect(path)

Solution 1:

Alternatively, Jsoup provides the W3CDom class with the method fromJsoup. This method transforms a Jsoup Document into a W3C document.

DocumentjsoupDoc= ...
W3CDomw3cDom=newW3CDom();
org.w3c.dom.Documentw3cDoc= w3cDom.fromJsoup(jsoupDoc);

UPDATE:

• Since 1.10.3 W3CDom is no longer experimental.
• Up to Jsoup 1.10.2 W3CDom class is still experimental.

Solution 2:

To retrieve a jsoup document via HTTP, make a call to Jsoup.connect(...).get(). To load a jsoup document locally, make a call to Jsoup.parse(new File("..."), "UTF-8").

The call to DomBuilder is correct.

When you say,

I used an available library DOMBuilder for this but when parsing I get org.w3c.dom.Document as null.

I think you mean, "I used an available library, DOMBuilder, for this but when printing the result, I get [#document: null]." At least, that was the result I saw when I tried printing the w3cDoc object - but that doesn't mean the object is null. I was able to traverse the document by making calls to getDocumentElement and getChildNodes.

publicstaticvoidmain(String[] args) {
    DocumentjsoupDoc=null;

    try {
        jsoupDoc = Jsoup.connect("http://stackoverflow.com/questions/17802445").get();
    } catch (IOException e) {
        e.printStackTrace();
    }

    org.w3c.dom.Document w3cDoc= DOMBuilder.jsoup2DOM(jsoupDoc);
    Elemente= w3cDoc.getDocumentElement();
    NodeListchildNodes= e.getChildNodes();
    Noden= childNodes.item(2);
    System.out.println(n.getNodeName());
}
