Need help with XalanNodeList

[Will Sappington]

I'm writing some code that's loosely based on the SerializeNodeSet
example.  I evaluate an XPath expression using selectNodeList() which
returns a NodeRefList of 3 nodes.  Each of them is an element and each
of them has 2 child elements, i.e.

 

<A>

    <B>BVaue</B>

    <C>CVaue</C>

    <D>DVaue</D>

</A>

(repeat twice)

 

I'm able to walk that list and display the node names and values.  I
need to descend into the child nodes and get their values.  So in a for
loop over the list of <A>'s, I get a XalanNode* with the item(i) method
and then do a getChildNodes() on that.  However, I get compile errors
when I try to use the XalanNodeList* that I get back from
getChildNodes().  I get "use of undefined type" errors trying to use the
node list pointer, specifically:

 

C:\Proj\src\libs\Profile\Profile.cpp(1588) : error C2027: use of
undefined type 'XalanNodeList'

        c:\proj\3rdparty\include\xalanc\xalandom\xalannode.hpp(32) : see
declaration of 'XalanNodeList'

 

I've tried casting the node pointer to an Element pointer based on some
code I found in the list archive, trying to give the node list a type
but that was no help.  Any help from someone here would be greatly
appreciated.  Relevant code snippets follow:

 

NodeRefList theResult;

theEvaluator.selectNodeList(theResult,

                            _domSupport,

                            pContextNode,

                            XalanDOMString(xpathExpr).c_str(),

                            _pXmlDoc->getDocumentElement());

 

const NodeRefList::size_type    theLength = theResult.getLength();

 

for (NodeRefList::size_type i = 0; i < theLength; ++i)

{

    XalanNode* theNode = theResult.item(i);

 

    assert(theNode != 0);

 

    const XalanNode::NodeType   theNodeType = theNode->getNodeType();

 

    displayNodeType(theNodeType);

 

    if (theNodeType == XalanNode::ELEMENT_NODE)

    {

        /* element node */

 

        if (theNode->hasChildNodes())

        {

            const XalanNodeList* pChildren = pParent->getChildNodes();

 

//===>      /* ** this line gets a compile error ** */

 

            unsigned int numChildren = pChildren->getLength();

 

            for (unsigned int i = 0; i < numChildren; i++)

            {

//===>          /* ** this line gets a compile error ** */

 

                XalanNode* pChild = pChildren->item(i);

 

                XalanDomCString nodeName(pChild->getNodeName());

                XalanDomCString nodeValue(pChild->getNodeValue());

 

                /* display name and value */

            }

        }

    }   /* end (element node) */

}
