python - 解析 XML Python

Question

我正在使用 xml.etree.ElementTree 来解析 XML 文件。我有个问题。我不知道如何在标签之间获取纯文本行。

<Sync time="4.496"/>
<Background time="4.496" type="music" level="high"/>

<Event desc="pause" type="noise" extent="instantaneous"/>
Plain text
<Sync time="7.186"/>

<Event desc="b" type="noise" extent="instantaneous"/>
Plain text
<Sync time="10.949"/>
Plain text

我已经有了这个代码:

import xml.etree.ElementTree as etree
import os

data_file = "./file.xml"

xmlD = etree.parse(data_file)
root = xmlD.getroot()
sections = root.getchildren()[2].getchildren()
for section in sections:
    turns = section.getchildren()
    for turn in turns:
        speaker = turn.get('speaker')
    mode = turn.get('mode')
    childs = turn.getchildren()

        for child in childs:
            time = child.get('time')
            opt = child.get('desc')
            if opt == 'es':
                 opt = "ESP:"
            elif opt == "la":
                 opt = "LATIN:"
            elif opt == "*":
                 opt = "-ININT-"
            elif opt == "fs":
                 opt = "-FS-"
            elif opt == "throat":
                 opt = "-THROAT-"
            elif opt == "laugh":
                 opt = "-LAUGH-"
            else:
                 opt = ""

            print speaker, mode, time, opt+child.tail.encode('latin-1')

我可以通过 XML 访问直到 Sync|Background|Event 标记，并且无法提取这些标记之后的文本。我放了一 block XML 文件，而不是整个文件。我只有最后一段代码有问题

非常感谢@alecxe。现在我可以获得我需要的信息。但是现在我有一个新的小问题。我获得了输入 tail 命令的行，但是之前生成了一个换行符 \n 或类似的东西，所以，我需要类似的东西:spk1 planned LAN: plain text from tail>

但是我明白了:

spk1 规划局域网:
来自尾部的纯文本

我尝试了很多东西，re.match() 模块，处理 XML 后的 sed 命令，但似乎没有 \n换行符，但我不能“放”纯文本!提前谢谢你

有人吗？谢谢!

这叫做 tail of an element :

The tail attribute can be used to hold additional data associated with the element. This attribute is usually a string but may be any application-specific object. If the element is created from an XML file the attribute will contain any text found after the element’s end tag and before the next tag.

定位Event标签，获取尾部，示例:

section.find("Event").tail
