DOM ERROR

[marco <m....@pisa.iol.it>]

Hi,
I have tried to use the DOM inside Xsp to do the Parsing of the Xml file
to which the Sheet style is associate. The part in which I do the
Parsing is the following:

<xsp:logic>
public void main () {
 String segno = request.getParameter("segnou");
 String scelta = request.getParameter("sceltau");
 try {

xspParser.parse("/usr/local/jakarta-tomcat/webapps/cocoon/prova31.xml");

  Document doc = xspParser.getDocument();
  analizza(doc);
 } catch (Exception e) {
  System.err.println("ERRORE NEL PARSING:"+e.getMessage() );
 }
}

public String analizza ( Document doc) {
 String err = "Non trovata nessuna corrispondenza";
 boolean trovato = false;
 Element elem = doc.getDocumentElement();
 NodeList nl = elem.getElementsByTagName("Segno");
 for ( int i=0; i&lt;nl.getLength(); i++) {
  Element segno = (Element)nl.item(i);
  NodeList nl1 = segno.getElementsByTagName("Zodiaco");
  Node zodiaco = nl1.item(0);
  if (
(((CharacterData)zodiaco.getFirstChild()).getData()).equals(segno))
trovato=true;
  if (trovato) {
   trovato=false;
   NodeList nl2 = segno.getElementsByTagName("Generale");
   Element generale = (Element)nl2.item(0);
   NodeList nl3 = generale.getElementsByTagName("Descrizione");
   Node descrizione = nl3.item(0);
   String s = (((CharacterData)descrizione.getFirstChild()).getData());
   return s;
  }
 }
 return err;
}

</xsp:logic>

Therefore I try to call the Main () function:

<xsl:when test="$sceltau='generale'">
<CORPO>
<xsp:expr>main()</xsp:expr>
</CORPO>
</xsl:when>

However the Cocoon returns me the following mistakes:

<h3 align="center">Error found handling the request.</h3>
<blockquote><pre>java.lang.Exception: XSP Java Compiler: Compilation

64: '}' expected.

    xspParentNode = xspCurrentNode;

Why?
Where are my errors?
Can I use DOM in a xsp page?
