漂亮地打印 xml 代码并放入变量中

Question

我刚刚在 Whosebug 上找到了这个打印 xml 代码的方法：

from xml.etree import ElementTree

def indent(elem, level=0):
    i = "\n" + level*"  "
    j = "\n" + (level-1)*"  "
    if len(elem):
        if not elem.text or not elem.text.strip():
            elem.text = i + "  "
        if not elem.tail or not elem.tail.strip():
            elem.tail = i
        for subelem in elem:
            indent(subelem, level+1)
        if not elem.tail or not elem.tail.strip():
            elem.tail = j
    else:
        if level and (not elem.tail or not elem.tail.strip()):
            elem.tail = j
    return elem        

root = ElementTree.parse('/tmp/xmlfile').getroot()
indent(root)
ElementTree.dump(root)

但是我想把我打印的内容放在一个变量中。我尝试了最简单的方法：

data = Elementtree.dump(root)
print("==>", data)

但它 returns 我 "==> None" 就像：ElementTree.dump(root) 无论如何都在打印。

感谢您的帮助

data = Elementtree.tostring(root)
print("==>", data)
