Yes: forget about regular expressions. ElementTree does that for free:

source = """
<xml>
<root></root>
<root/>
<root><frame type="image"><action></action></frame></root>
<root><frame type="image"><action/></frame></root>
</xml>
"""

import xml.etree.ElementTree as ET
tree = ET.XML(source)
print ET.tostring(tree)

output:

<xml>
<root />
<root />
<root><frame type="image"><action /></frame></root>
<root><frame type="image"><action /></frame></root>
</xml>
