在python中检索元素的所有文本，包括其子元素 [英] Retrieve all text of an element including its child in python

问题描述

我编写了一个代码来查找 xml 中特定标签中的文本.它适用于没有子标签的标签.

i wrote a code to find text in specific tags in an xml. It works fine for tags without a child tag.

For e.g. 1 <a>ajsaka</a>. it works fine for this. 

e.g. 2 But if there is an instance of <b>ahsjd<c>jjiij</c>aa</b>. 

它不起作用.我想要标签中的所有内容，包括其子元素文本.我希望它打印 ahsjdjjiijaa，但它只打印 ahsjd.到目前为止，这是我的代码.

It doesnt work. I want all the content in a tag including its child element text. I want it to print ahsjdjjiijaa, but instead it prints only ahsjd. Here is my code so far.

这是输入文件.

<level>
<ex>
<nt>[edit <topic-ref link-text="short-title"
topic-id="13629">address</topic-ref>],</nt>
<nt>[edit routing-instances <var>routing-instance-name</var
    > <topic-ref link-text="short-title" topic-id="13629">address-
assignment</topic-ref
>]</nt>
</ex>
   <exam>
   </exam>
</level>

from lxml import etree
doc=etree.parse('C:/xx/bb.xml')
root=doc.getroot()
node=root.find('level')
count=len(node.getchildren())
print (count)
for elem in root.findall('level/ex/nt'):
    print (elem.text)

我如何获得它?

推荐答案

您可以将文件作为字符串读取，然后在标签之间连接所有文本

You can read your file as string, then concatinate all text between tags

import xml.etree.ElementTree as ET
text = open('C:/xx/bb.xml').read()
''.join(ET.fromstring(text).itertext())

输出:

'ahsjdjjiijaa'
