Access Violation on eVC++4

[John Idol]

Hi All,

I am using tinyXML on eVC++4.
Everything works fine but out of nowhere I have an Access Violation on a call to the ToElement() method of the TiXmlNode. Strange thing is that I am calling it before several times without any problem.

my code:

TiXmlNode* node = 0;
TiXmlElement* modelElement = 0;
TiXmlNode* rootNode = 0;

rootNode = m_doc.RootElement();

node = rootNode;
testData.TagAValue = GetTagA(node);
node = rootNode;
testData.TagBValue = GetGetTagB(node);
node = rootNode;
testData.TagCValue = GetTagC(node);//<--Access violation in Here
//...And so forth

the GetTag functions are very similar and they look something like:

CString GetTagC(TiXmlNode* node)
{
        CString tempStr = _T("");
        TiXmlElement* modelElement = 0;

        node = node->FirstChild(C_TAG_LIST);
        node = node->FirstChild(C_TAG);
        modelElement = node->ToElement();//<--Access Violation on this LINE!!!
        for( modelElement; modelElement; modelElement=modelElement->NextSiblingElement())
        {
                tempStr = modelElement->Attribute(META_NAME);
                if (tempStr == MY_C_NAME_ATTRIBUTE)
                {
                        tempStr = modelElement->Attribute(META_VALUE);
                        return tempStr;
                }
        }
       
        return _T("");
}

I an doing the same things on each so why is it crashing on GetTagC?
Any help/suggestion/clue would be higly appreciated!

Thanks

I was looking for the wrong TAG:

node = node->FirstChild(C_TAG);

and then accessing it without checking the result.
