用Python打印XML非常漂亮

用Python打印XML的最佳方法(或各种方法)是什么?

当前回答

我发现了一个快速简单的方法来格式化和打印一个xml文件:

import xml.etree.ElementTree as ET

xmlTree = ET.parse('your XML file')
xmlRoot = xmlTree.getroot()
xmlDoc =  ET.tostring(xmlRoot, encoding="unicode")

print(xmlDoc)

Outuput:

<root>
  <child>
    <subchild>.....</subchild>
  </child>
  <child>
    <subchild>.....</subchild>
  </child>
  ...
  ...
  ...
  <child>
    <subchild>.....</subchild>
  </child>
</root>

另一个解决方案是借用这个缩进函数，用于自2.5以来内置在Python中的ElementTree库。下面是它的样子:

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)

你可以使用流行的外部库xmltodict, unparse和pretty=True，你会得到最好的结果:

xmltodict.unparse(
    xmltodict.parse(my_xml), full_document=False, pretty=True)

full_document=False <?xml version="1.0" encoding="UTF-8"?>在最上面。

使用etree。缩进和etree.tostring

import lxml.etree as etree

root = etree.fromstring('<html><head></head><body><h1>Welcome</h1></body></html>')
etree.indent(root, space="  ")
xml_string = etree.tostring(root, pretty_print=True).decode()
print(xml_string)

输出

<html>
  <head/>
  <body>
    <h1>Welcome</h1>
  </body>
</html>

删除名称空间和前缀

import lxml.etree as etree


def dump_xml(element):
    for item in element.getiterator():
        item.tag = etree.QName(item).localname

    etree.cleanup_namespaces(element)
    etree.indent(element, space="  ")
    result = etree.tostring(element, pretty_print=True).decode()
    return result


root = etree.fromstring('<cs:document xmlns:cs="http://blabla.com"><name>hello world</name></cs:document>')
xml_string = dump_xml(root)
print(xml_string)

输出

<document>
  <name>hello world</name>
</document>

如果由于某种原因你无法获得其他用户提到的任何Python模块，我建议使用以下Python 2.7解决方案:

import subprocess

def makePretty(filepath):
  cmd = "xmllint --format " + filepath
  prettyXML = subprocess.check_output(cmd, shell = True)
  with open(filepath, "w") as outfile:
    outfile.write(prettyXML)

据我所知，这种解决方案适用于安装了xmllint包的基于unix的系统。
