Output Screenshot

Root node is 'rootNode'

Notes

* The value returned from the xmlParseMemory() function should be compared against the NULL constant to ensure its success.

* The name member of the xmlNodePtr structure contains the element's name. For the root element, this string is output at Line 22.
