How to handle tinyxml null pointer returned on GetText()

Question

TiXmlElement *pElem;    
std::string StatusResponse;
pElem = hResponse.FirstChild("StatusResponse").Element();

if (pElem)
    StatusResponse = pElem->GetText();

If pElem is valid but the element contains no text, pElem->GetText() returns a NULL pointer, causing an exception. How should I handle this?

Thanks.

if (pElem && pElem->GetText())
    StatusResponse = pElem->GetText();

How painfully obvious. Thank you very much.

I would store the return value of GetText() to a local variable to avoid calling GetText() twice.
