getTextContent in Java extension function

[Christian Schröder <cs...@deriva.de>]

Hi list,
I have written a java extension function that is used during this xslt 
transformation:
    <xsl:value-of select="src:myFunction(foo)"/>
"foo" is a node in my xml document:
    <foo>Some Text</foo>
This is the function:
    public static String myFunction(org.w3c.dom.Node n) {
       String s = n.getTextContent();
       // Some more stuff ...
    }
According to the java 1.5 documentation, the "getTextContent" method 
should return the "concatenation of the textContent attribute value of 
every child node", i.e. in this case: "Some Text". However, the function 
returns null.

The Node n is of type org.apache.xml.dtm.ref.DTMNodeProxy. This is the 
code from the svn repository:
    public String getTextContent() throws DOMException {
        return getNodeValue();  // overriden in some subclasses
    }

Of course, "getNodeValue" returns null for the "foo" node, but I think 
this is not the way "getTextContent" should be implemented. Is this a 
bug or do I miss anything?

Regards,
    Christian

It looks like a bug in the implementation of getTextContent.  May I ask 
you to open a bug report?

Thanks,

Henry
