A little clumsy solution without lxml :-)

data = """<root>

    <head></head>    <content></content>

</root>"""

data3 = []
data2 = data.split('\n')
for x in data2:
    y = x.strip()
    if y: data3.append(y)
data4 = ''.join(data3)
data5 = data4.replace("  ","").replace("> <","><")

print data5

Output: <root><head></head><content></content></root>

The only thing that bothers me about xml.dom.minidom's toprettyxml() is that it adds blank lines. I don't seem to get the split components, so I just wrote a simple function to remove the blank lines:

#!/usr/bin/env python

import xml.dom.minidom

# toprettyxml() without the blank lines
def prettyPrint(x):
    for line in x.toprettyxml().split('\n'):
        if not line.strip() == '':
            print line

xml_string = "<monty>\n<example>something</example>\n<python>parrot</python>\n</monty>"

# parse XML
x = xml.dom.minidom.parseString(xml_string)

# clean
prettyPrint(x)

And this is what the code outputs:

<?xml version="1.0" ?>
<monty>
        <example>something</example>
        <python>parrot</python>
</monty>

If I use toprettyxml() by itself, i.e. print(toprettyxml(x)), it adds unnecessary blank lines:

<?xml version="1.0" ?>
<monty>


        <example>something</example>


        <python>parrot</python>


</monty>
