/** Convenience function for easy access to the text inside an element. Although easy
* and concise, GetText() is limited compared to getting the TiXmlText child
* and accessing it directly.
*
* If the first child of 'this' is a TiXmlText, the GetText()
* returns the character string of the Text node, else null is returned.
*
* This is a convenient method for getting the text of simple contained text:
* @verbatim
* <foo>This is text</foo>
* const char* str = fooElement.GetText();
* @endverbatim
*
* 'str' will be a pointer to "This is text".
*
* Note that this function can be misleading. If the element foo was created from
* this XML:
* @verbatim
* <foo><b>This is text</b></foo>
* @endverbatim
*
* then the value of str would be null. The first child node isn't a text node, it is
* another element. From this XML:
* @verbatim
* <foo>This is <b>text</b></foo>
* @endverbatim
* GetText() will return "This is ".
*
* WARNING: GetText() accesses a child node - don't become confused with the
* similarly named TiXmlHandle::Text() and TiXmlNode::ToText() which are
* safe type casts on the referenced node.
