'Transform' with 'XPath'

Onk!

I am trying to add a XPath element to the XPATH transform but whatever I try, I get a "DOM005 Wrong document"  exception

This is what I try:

	//exclude SOAP 'Actor' from signature generation:
      Document doc= new DocumentImpl();
      Element xpathElem = doc.createElement("XPath");
      xpathElem.appendChild( doc.createTextNode("(xpath expression here)") );
	
	Transforms transforms = new Transforms(myDOMDocumentToSign);
	transforms.addTransform(Transforms.TRANSFORM_XPATH, xpathElem);
	>>>> will throw the exception.

Any idea?

Thx in advance.

P.S.: The XPath I try to add is:
" not (ancestor-or-self::node()[@SOAP:actor=&quot;urn:oasis:names:tc:ebxml-msg:actor:nextMSH&quot;] | ancestor-or-self::node()[@SOAP:actor=&quot;http://schemas.xmlsoap.org/soap/actor/next&quot;] )"

Hi Frank,

you create an Element using doc and want to insert it into 
myDOMDocumentToSign. That's the problem. You must simply say

Element xpathElem = 
myDOMDocumentToSign.createElementNS(Constants.NamespaceSpexNS, "XPath");
xpathElem.appendChild( myDOMDocumentToSign.createTextNode("(xpath 
expression > here)"));

(Please note that the xpathElement MUST be created in the XMLSignature 
Namespace.)

BTW, you don't have to do this by hand. Use 
org.apache.xml.security.transforms.params.XPathContainer instead:

XPathContainer xpath = new XPathContainer(myDOMDocumentToSign);
xpath.setXPath("(xpath expression > here)");
Transforms transforms = new Transforms(myDOMDocumentToSign);
transforms.addTransform(Transforms.TRANSFORM_XPATH, xpath.getElement());
