// if needed override tag that you don't want to parse to DummyTagProcessor
htmlTagProcessorFactory.addProcessor("img", new DummyTagProcessor());
htmlTagProcessorFactory.addProcessor("link", new DummyTagProcessor());
// Create a fresh configuration and set needed configuration objects.
XMLWorkerConfigurationImpl config = new XMLWorkerConfigurationImpl();
// Attach the default CSS to a new CSSResolver
CssFile defaultCSS = new XMLWorkerHelper().getDefaultCSS();
StyleAttrCSSResolver cssResolver = new StyleAttrCSSResolver();
cssResolver.addCssFile(defaultCSS);
// attach more CSS files if needed
cssResolver.addCssFile(otherCssFile);
// set the TagProcessorFactory
config.tagProcessorFactory(htmlTagProcessorFactory).cssResolver(cssResolver)
		.acceptUnknown(true);
// create a document
final Document doc = new Document();
doc.setPageSize(PageSize.A4);
// create writer
PdfWriter writer = PdfWriter.getInstance(doc, outputStream);
writer.setPageEvent(new WatermarkEvent());
// set margins for first page
float margin = CssUtils.getInstance().parsePxInCmMmPcToPt("8px");
doc.setMargins(margin, margin, margin, margin);
// OPEN the document !
doc.open();
config.document(doc).pdfWriter(writer);
// create the worker
final XMLWorker worker = new XMLWorkerImpl(config);
// attach an ElementHandler
worker.setDocumentListener(new ElementHandler() {
	public void addAll(final List<Element> arg0) throws DocumentException {
		for (Element e : arg0) {
			doc.add(e);
		}
	}
	public void add(final Element e) throws DocumentException {
		doc.add(e);
	}
});
// Set the worker in the parser and start parsing
XMLParser p = new XMLParser(worker);
p.parse(new StringReader(content));
writer.close();

Source: https://github.com/itext/itextpdf/blob/develop/xmlworker/src/test/resources/com/itextpdf/tool/xml/examples/css/div/complexDiv01/complexDiv_files/sh088.htm

Manages user IDs, including updating, setting, getting, and checking their validity. It handles anonymous users and ensures ID consistency.

```javascript
(function(f,g,k){var e,m=f,o=f.util,d="0000000000000000",h=0;function j(a){if(a==="anonymous"){return true;}return o.ivc(a);}function l(){var q=m.cookie.rck("uid"),r=!!_atc.xck,a,p=m.cookie.cww();if(!h){if(q&&j(q)){m.uf=0;if(q==="anonymous"){q=d;m.uf=2;}if(p){if(q==d){a=new Date();a.setYear(a.getFullYear()+10);}m.cookie.sck("uid",q,0,0,a);}else{q="x";}}else{if(q||q===""){m.uf=2;}else{m.uf=1;}if(p){q=o.cuid();m.cookie.sck("uid",q);}else{q="x";}}h=1;}m.uid=q;if(q){m.dat.uid=q;}}function i(a){try{var q=((m.bro.ie8||m.bro.ie9)&&window.external&&window.external.InPrivateFilteringEnabled()===true);}catch(p){}if(q||m.uid==="anonymous"||m.uid==="0000000000000000"||(navigator.doNotTrack&&navigator.doNotTrack!="unspecified"&&navigator.doNotTrack!="no")){
_atc.xck=1;
m.uid="0000000000000000";
return 1;
}
return 0;
}
function n(a){m.uid=a;i();}
function b(){var a=m.uid;
return a&&j(a)?"&uid="+_euc(m.uid):"";}
function c(){var a=m.uid;
return a&&j(a)?a:"x";}
if(!f.cookie){f.cookie={};}
f.cookie.uid={update:l,set:n,get:c,toKV:b,isValid:j,check:i};
})(window,window.api,window);
