Question

我想压扁lxml etree（特别是HTML，如果重要的话。）我如何获得树中所有元素的平面列表？

Answer 1

您可以使用.iter()方法，如下所示：

from lxml import etree

xml = etree.XML('''<html><body>
                   <p>hi there</p><p>2nd paragraph</p>
                   </body></html>''')

# If you want to visit all of the descendants
for element in xml.iter():
    print element.tag

# Or, if you want to have a list of all the descendents
all_elements = list(xml.iter())
print [element.tag for element in all_elements]
