Once the user has entered the URL they want to add to the form. You can use the loadXML function to implement some special text in a label...
var linkValue = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><exData contentType=\"text/html\" xmlns=\"http://www.xfa.org/schema/xfa-template/2.8/\"><body xmlns=\"http://www.w3.org/1999/xhtml\" xmlns:xfa=\"http://www.xfa.org/schema/xfa-data/1.0/\" xfa:APIVersion=\"Acroform:2.7.0.0\" xfa:spec=\"2.1\"><p style=\"font-weight:bold;text-decoration:none;letter-spacing:0in\">The new link the user have entered is:<a href=\"" + textfield.rawValue + "\">textfield.rawValue</a></p></body></exData>";
this.resolveNode("lblURL").value.exData.loadXML(linkValue, 1, 1);
