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

from lxml import etree
import xml.dom.minidom as mmd

xml_root = etree.parse(xml_fiel_path, etree.XMLParser())

def print_xml(xml_root):
    plain_xml = etree.tostring(xml_root).decode('utf-8')
    urgly_xml = ''.join(plain_xml .split())
    good_xml = mmd.parseString(urgly_xml)
    print(good_xml.toprettyxml(indent='    ',))

它的工作良好的xml与中国!

你可以试试这种变化……

安装BeautifulSoup和后端lxml(解析器)库:

user$ pip3 install lxml bs4

处理XML文档:

from bs4 import BeautifulSoup

with open('/path/to/file.xml', 'r') as doc: 
    for line in doc: 
        print(BeautifulSoup(line, 'lxml-xml').prettify())

从Python 3.9开始，ElementTree有一个用于漂亮打印XML树的indent()函数。

见https://docs.python.org/3/library/xml.etree.elementtree.html # xml.etree.ElementTree.indent。

示例用法:

import xml.etree.ElementTree as ET

element = ET.XML("<html><body>text</body></html>")
ET.indent(element)
print(ET.tostring(element, encoding='unicode'))

好处是它不需要任何额外的库。欲了解更多信息，请访问https://bugs.python.org/issue14465和https://github.com/python/cpython/pull/15200

下面是我解决难看的文本节点问题的解决方案。

uglyXml = doc.toprettyxml(indent='  ')

text_re = re.compile('>\n\s+([^<>\s].*?)\n\s+</', re.DOTALL)    
prettyXml = text_re.sub('>\g<1></', uglyXml)

print prettyXml

上面的代码将产生:

<?xml version="1.0" ?>
<issues>
  <issue>
    <id>1</id>
    <title>Add Visual Studio 2005 and 2008 solution files</title>
    <details>We need Visual Studio 2005/2008 project files for Windows.</details>
  </issue>
</issues>

而不是这样:

<?xml version="1.0" ?>
<issues>
  <issue>
    <id>
      1
    </id>
    <title>
      Add Visual Studio 2005 and 2008 solution files
    </title>
    <details>
      We need Visual Studio 2005/2008 project files for Windows.
    </details>
  </issue>
</issues>

免责声明:可能有一些限制。

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>

import xml.dom.minidom

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