Getting cleaned HTML in text from HtmlCleaner

Question

I want to see the cleaned HTML that we get from HTMLCleaner. I see there is a method called serialize on TagNode, however don't know how to use it. Does anybody have any sample code for it?

Thanks Nayn

Answer 1

Here's the sample code:

HtmlCleaner htmlCleaner = new HtmlCleaner();

TagNode root = htmlCleaner.clean(url);

HtmlCleaner.getInnerHtml(root);

String html = "<" + root.getName() + ">" + htmlCleaner.getInnerHtml(root) + "</" + root.getName() + ">";

Use a subclass of org.htmlcleaner.XmlSerializer, for example:

// get the element you want to serialize
HtmlCleaner cleaner     = new HtmlCleaner();
TagNode     rootTagNode = cleaner.clean(url);

// set up properties for the serializer (optional, see online docs)
CleanerProperties cleanerProperties = cleaner.getProperties();
cleanerProperties.setOmitXmlDeclaration(true);

// use the getAsString method on an XmlSerializer class
XmlSerializer xmlSerializer = new PrettyXmlSerializer(cleanerProperties);
String        html          = xmlSerializer.getAsString(rootTagNode);
