Hi,
My problem is :

In a XSL file I make a call to an external function :

<xsl:value-of select="external:ListToXML()"/>

The function ListToXML() is like thatt :

XObjectPtr NGATranslatorXSLFunctionListToXML::execute(
        XPathExecutionContext&       io__executionContext,
        XalanNode*                   io__context,
        const XObjectArgVectorType&  i__args,
        const LocatorType*           i__locator) const
{
    string l__xml;
    
    l__xml = "<exemple>exemple1</exemple><exemple>exemple2</exemple>";
     
    return io__executionContext.getXObjectFactory().createString(
                                                    XalanDOMString(
                                                            l__xml.c_str())
                                                            );
}


What I get in output (after transformation) is a XML part like that :

&lt;exemple&gt;exemple1&lt;/exemple&gt;&lt;exemple&gt;exemple2&lt;/exemple&gt;
You asked for a string, which, when copied to the source tree, creates a 
text node.  During serialization, markup characters are escaped so the 
result is well-formed.


How can I get a correct XML part ?
You want to return either a result tree fragment or a node set.  It's 
simpler to return a node set, although it's not the best choice if your 
stylesheet will be generating lots of these node sets.

Take a look at the implementation of the document() function, which is 
implemented in src/xalanc/XSLT/FunctionDocument.cpp for more details.

Also, please remember that functions in XPath anbd XSLT must be free of 
side-effects.  That means that no matter how many times your function is 
called, if it's called with the same arguments, it must produce the same 
result.
