def votable_handler(xml_table):
"""
Returns a VOtable object from a VOtable style xml string
In order to get a VOtable object, it has to be parsed from an xml file or
file-like object. This function creates a file-like object via the
StringIO module, writes the xml data to it, then passes the file-like
object to parse_single_table() from the astropy.io.votable.table module
and thereby creates a VOtable object.
Parameters
----------
xml_table: str
Contains the VOtable style xml data
Returns
-------
votable: astropy.io.votable.tree.Table
A properly formatted VOtable object
Examples
--------
>>> temp = hec.suds_unwrapper(xml_string)
>>> type(temp)
unicode
>>> temp = hec.votable_handler(temp)
>>> type(temp)
