漂亮地打印xml代码并放入变量中

Question

我刚刚在Stackoverflow上发现了此方法以打印xml代码：

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)

但是我想将打印的内容放入变量中。 我尝试了最简单的方法：

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

但是它返回我“ ==>无” 就像：ElementTree.dump（root）无论什么都在打印。

感谢您的帮助

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