strange switch case problem

[lucky6969b]

template<class T>
T GetValue<T>::get(TiXmlNode* pParent)
{
	T attr;
	if ( !pParent ) return attr;

	TiXmlNode* pChild;
	TiXmlText* pText;
	int t = pParent->Type();
	
	 
 

	switch ( t )
	{
	case TiXmlNode::TINYXML_DOCUMENT:
	 
		break;

	case TiXmlNode::TINYXML_ELEMENT:
	 
		 attr =get_attribs(pParent->ToElement());
		break;

	case TiXmlNode::TINYXML_COMMENT:
	 
		break;

	case TiXmlNode::TINYXML_UNKNOWN:
		 
		break;

	case TiXmlNode::TINYXML_TEXT:
		pText = pParent->ToText();
		 
		break;

	case TiXmlNode::TINYXML_DECLARATION:
		 
		break;
	default:
		break;
	}
	 
	for ( pChild = pParent->FirstChild(); pChild != 0; pChild = pChild->NextSibling()) 
	{
		get( pChild );
	}

	return attr;

}

A breakpoint at
case TiXmlNode::TINYXML_DOCUMENT:

break; // here

is never hit, why? It falls thru to the for loop straight off. The matching value is correct.
Thanks

Well, if map and terrain don't match trust the terrain.

The term "fall through" has a very specific meaning in the context of switch statements. You should look it up.

What likely happens, is that the compiler implements the switch statement as a jump table and directly jumps to the next statement based on the value used in the switch. The break is only a control statement and doesn't really do anything, so it is skipped.
