如何使用xml.etree.ElementTree关闭python中的一个标签后如何提取嵌套xml中的文本 [英] How to extract text in nested xml after closing of one tag in python using xml.etree.ElementTree

问题描述

我想提取xml文档中的所有文本，并且在以下情况下遇到问题：

I want to extract all text in xml document, and I am having a problem for the following case:

...
<a>
hello
<B>
there
</B>
How was your day.

.....
</a>

在此代码段中，我可以得到文本 hello和 there，因为我可以得到它们使用以下标记：

In this snippet, I can get the text "hello" and "there" because I can get them using the following tags:

a.text
b.text

但我不知道如何访问您今天过的怎么样。

but I don't know how to access the "How was your day." part.

推荐答案

您正在寻找元素的 .tail 属性：

You are looking for the .tail attribute of an element:

>>> from xml.etree import ElementTree
>>> example = ElementTree.fromstring('''\
... <a>
... hello
... <B>
... there
... </B>
... How was your day.
... </a>
... '''
... )
>>> example
<Element 'a' at 0x10715d150>
>>> example.text
'\nhello\n'
>>> example.find('B')
<Element 'B' at 0x10715d7d0>
>>> example.find('B').text
'\nthere\n'
>>> example.find('B').tail
'\nHow was your day.\n'
