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

我用几行代码解决了这个问题，打开文件，通过它并添加缩进，然后再次保存它。我使用的是小的xml文件，不想添加依赖项，也不想为用户安装更多的库。总之，这是我最后得出的结论:

    f = open(file_name,'r')
    xml = f.read()
    f.close()

    #Removing old indendations
    raw_xml = ''        
    for line in xml:
        raw_xml += line

    xml = raw_xml

    new_xml = ''
    indent = '    '
    deepness = 0

    for i in range((len(xml))):

        new_xml += xml[i]   
        if(i<len(xml)-3):

            simpleSplit = xml[i:(i+2)] == '><'
            advancSplit = xml[i:(i+3)] == '></'        
            end = xml[i:(i+2)] == '/>'    
            start = xml[i] == '<'

            if(advancSplit):
                deepness += -1
                new_xml += '\n' + indent*deepness
                simpleSplit = False
                deepness += -1
            if(simpleSplit):
                new_xml += '\n' + indent*deepness
            if(start):
                deepness += 1
            if(end):
                deepness += -1

    f = open(file_name,'w')
    f.write(new_xml)
    f.close()

这对我来说很有用，也许有人会用到它:)

import xml.dom.minidom

dom = xml.dom.minidom.parse(xml_fname) # or xml.dom.minidom.parseString(xml_string)
pretty_xml_as_string = dom.toprettyxml()

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>

如果你使用的是DOM实现，每一个都有自己的内置漂亮打印形式:

# minidom
#
document.toprettyxml()

# 4DOM
#
xml.dom.ext.PrettyPrint(document, stream)

# pxdom (or other DOM Level 3 LS-compliant imp)
#
serializer.domConfig.setParameter('format-pretty-print', True)
serializer.writeToString(document)

如果您正在使用其他没有自己的漂亮打印机的东西——或者那些漂亮打印机不能完全按照您想要的方式来做——您可能必须编写或子类化您自己的序列化器。

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。
