Apache DTM Plaintext für css-Abfrage

Question

Ich schreibe einen XPath-Funktion Ausdruck, um Elemente durch CSS-Abfrage zu finden. Diese

ist, was ich habe:

import javax.xml.transform.TransformerException;  
import org.apache.xml.dtm.ref.dom2dtm.DOM2DTM; 
import org.apache.xpath.XPathContext; 
import org.apache.xpath.functions.FunctionOneArg; 
import org.apache.xpath.objects.XObject; 
import org.apache.xpath.objects.XString; 
import org.jsoup.Jsoup; 
import org.jsoup.nodes.Document; 
import org.jsoup.nodes.Element; 
import org.jsoup.select.Elements; 

public class CSSFinder extends FunctionOneArg { 
    @Override 
    public XObject execute(XPathContext c) throws TransformerException { 
     final DOM2DTM dtm = (DOM2DTM) c.getDTM(c.getContextNode()); 
     final Document parse = Jsoup.parse(dtm.toString()); // toString returns not html. 
     final Elements parents = parse.select(getArg0().toString()).first().parents(); 
     String xpath = "/"; 
     for (final Element parent : parents) { 
      xpath += "/*[" + parent.elementSiblingIndex() + "]"; 
     } 
     // replace this later... 
     return new XString("sc-login"); 
    } 
} 

Das Problem ist, dass toString nicht html zurückgibt. Wie bekomme ich das komplette geparste HTML?

die Lösung gefunden:

<clickElement xpath="wt:css('button.sc-login')" />

public class CSSFinder extends FunctionOneArg { 
    @Override 
    public XObject execute(XPathContext c) throws TransformerException { 
     final DOM2DTM currentNode = (DOM2DTM) c.getDTM(c.getContextNode()); 
     final Node root = currentNode.getNode(currentNode.getDocumentRoot(c.getContextNode())); 
     final Transformer transformer = TransformerFactory.newInstance().newTransformer(); 
     final ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); 
     transformer.transform(new DOMSource(root), new StreamResult(outputStream)); 
     try { 
      outputStream.close(); 
     } catch (final IOException e) { 
      e.printStackTrace(); 
     } 
     final Document parse = Jsoup.parse(outputStream.toString()); 
     final Element current = parse.select(getArg0().toString()).first(); 
     final Elements parents = current.parents(); 
     Collections.reverse(parents); 
     String xpath = ""; 
     for (final Element parent : parents) { 
      final int index = parent.elementSiblingIndex() + 1; 
      xpath += "/*[" + index + "]"; 
     } 
     xpath += "/*[" + (current.elementSiblingIndex()+1) + "]"; 
     return new XNodeSetForDOM((Node) XPathUtils.getByXPath(root, xpath).get(0), c.getDTMManager()); 
    } 
} 

ich die Funktion

XPathHelper.registerGlobalFunction("http://webtest.canoo.com", "css", CSSFinder.class); 

Und hier sind wir in canoo webtest gehen registrieren müssen
