get_xml_iterator

astropy.utils.xml.iterparser.get_xml_iterator(*args, **kwds)

Returns an iterator over the elements of an XML file.

The iterator doesn’t ever build a tree, so it is much more memory and time efficient than the alternative in cElementTree.

Parameters:

fd : readable file-like object or read function

Returns:

parts : iterator

The iterator returns 4-tuples (start, tag, data, pos):

• start: when True is a start element event, otherwise an end element event.

• tag: The name of the element

• data: Depends on the value of event:

  • if start == True, data is a dictionary of attributes
  • if start == False, data is a string containing the text content of the element

• pos: Tuple (line, col) indicating the source of the event.
