Knowing how deep in the tree i am?

[Fredrik Brännbacka]

void walkScript(TiXmlElement* element)
{
    TiXmlElement* child = 0;
    for( child = element->FirstChildElement(); child; child = child->NextSiblingElement() )
    {
        string tag = child->Value();
        printf("%s\n",child->Value());       
        walkScript(child->ToElement());
    }
}

Hi i have a function that looks something like this to walk all nodes.
But i need to know how deep i am, like this:

<tag> depth 0
    <tag> depth 1
        <tag></tag> depth 2
    </tag> depth 1
</tag> depth 0

Thanks In Advance

Why not do the standard recursive strategy of passing in a variable to walkScript?

like

void walkScript(TiXmlElement* element, int depth=0) 
{ 
TiXmlElement* child = 0;
for( child = element->FirstChildElement(); child; child = child->NextSiblingElement() )
{
string tag = child->Value();
printf("%s Depth %d\n",child->Value(), depth); 
walkScript(child->ToElement(), depth+1);
}
}

?

No worries.
We all have those moments :)
