[jira] Commented: (XMLBEANS-200) XmlObject node copy yields IllegalArgumentException: DocumentWrapper#wrap in Saxon on further XPath executions of copied node

["Raman Gupta (JIRA)" <xm...@xml.apache.org>]

Raman Gupta commented on XMLBEANS-200:
--------------------------------------

This problem also occurs if you use an XmlCursor to create an XmlObject (as opposed to using the parse method).  Here is some sample code:

        XmlObject xmlInput = XmlObject.Factory.newInstance();
        XmlCursor cursor = xmlInput.newCursor();
        cursor.toNextToken();
        cursor.push();
        cursor.beginElement("E1005");
        cursor.insertElementWithText("E1", null);
        cursor.pop();
        cursor.dispose();

        XmlObject[] xmlResult = xmlInput.execQuery(expression);    // throws exception given in description

The only workaround I have for now is to do:

        xmlInput = XmlObject.Factory.parse(xmlInput.getDomNode());

before calling execQuery.

> A selectPath(Query)  returns a child node of the wrapped document.  The child node is then copied with the XmlObject.copy() method. My application requires a copy of the child node since it will be passed into a Threaded application which has no need to modify the resulting XML. The Child node has further children that I would like to use XPath queries to pull the desired node. However, when I issue a select path on the returned child node, I get the following error:
> java.lang.IllegalArgumentException: DocumentWrapper#wrap: supplied node does not belong to the wrapped DOM document
> I do not wish to construct a new XML document for the Child (and its children) to pass into my application. I just need the fragment to query, as the XML just represents "ini" type information.
