Hierarchy of a node

Question

hi guys,
please any one would like to let me know is there a way to get to know about all possible elements and attributes of a root without visualizing them. In case if we have a large xml file then it is very hard to pick all possible elements. For example: first glance i have
Root
<place>
<_id>20house</_id>
<_rev></_rev>
<about>20house</about>
<place>
<place>
<_id>20house</_id>
<_rev></_rev>
<about>20house</about>
<place>
<place>
<_id>20house</_id>
<_rev></_rev>
<*status>published</status>*
*<gislatitude>-37.75159</gislatitude>*
<place>
<place>
<_id>20house</_id>
<_rev></_rev>
<status>published</status>
*<hasbookatablelink>no</hasbookatablelink>*
<place>
Best Regards,
Abida
