Python and ElementTree: return "inner XML" excluding parent element

This is based on the other solutions, but the other solutions did not work in my case (resulted in exceptions) and this one worked:

from xml.etree import Element, ElementTree

def inner_xml(element: Element):
    return (element.text or '') + ''.join(ElementTree.tostring(e, 'unicode') for e in element)

Use it the same way as in Mark Tolonen's answer.

How about:

from xml.etree import ElementTree as ET

xml = '<root>start here<child1>some text<sub1/>here</child1>and<child2>here as well<sub2/><sub3/></child2>end here</root>'
root = ET.fromstring(xml)

def content(tag):
    return tag.text + ''.join(ET.tostring(e) for e in tag)

print content(root)
print content(root.find('child2'))

Resulting in:

start here<child1>some text<sub1 />here</child1>and<child2>here as well<sub2 /><sub3 /></child2>end here
here as well<sub2 /><sub3 />

The following worked for me:

from xml.etree import ElementTree as etree
xml = '<root>start here<child1>some text<sub1/>here</child1>and<child2>here as well<sub2/><sub3/></child2>end here</root>'
dom = etree.XML(xml)

(dom.text or '') + ''.join(map(etree.tostring, dom)) + (dom.tail or '')
# 'start here<child1>some text<sub1 />here</child1>and<child2>here as well<sub2 /><sub3 /></child2>end here'

dom.text or '' is used to get the text at the start of the root element. If there is no text dom.text is None.

Note that the result is not a valid XML - a valid XML should have only one root element.

Have a look at the ElementTree docs about mixed content.
