Question

我有一个以下的xml文件，我想阅读<seg>中的内容并使用Python将它们保存到纯文本文件中。我使用了DOM模块。

＆＃13;

<?xml version="1.0"?>
<mteval>
  <tstset setid="default" srclang="any" trglang="TRGLANG" sysid="SYSID">
    <doc docid="ntpmt-dev-2000/even1k.cn.seg.txt">
      <seg id="1">therefore , can be obtained having excellent properties ( good stability and solubility of the balance of the crystal as a pharmaceutical compound is not possible to predict .</seg>
      <seg id="3">compound ( I ) are preferably crystalline , in particular , has good stability and solubility equilibrium and suitable for industrial prepared type A crystal is preferred .</seg>
      <seg id="4">method B included in the catalyst such as DMF , and the like in the presence of a compound of formula ( II ) with thionyl chloride or oxalyl chloride to give an acyl chloride , in the presence of a base of the acid chloride with alcohol ( IV ) ( O ) by reaction of esterification .</seg>
    </doc>
  </tstset>
</mteval>

＆＃13;

from xml.dom.minidom import parse
import xml.dom.minidom

dom = xml.dom.minidom.parse(r"path_to_xml file")
file = dom.documentElement
seg = dom.getElementsByTagName("seg")
for item in seg:
    sent = item.firstChild.data
    print(sent,sep='')

file = open(r'file.txt','w')
file.write(sent)
file.close()

在上面的代码上运行时，它会成功打印屏幕上的所有行，但file.txt只有一行最后<seg>（seg id = 4），实际上我想将所有句子保存到文件。我的代码有问题吗？

您只需调用file.write(sent)一次，在循环之前打开文件，然后将以下行添加到此代码中：

file = open(r'file.txt','w')

for item in seg:
    sent = item.firstChild.data
    print(sent,sep='')
    file.write(sent) // <---- this line

file.close()

如何阅读xml文件的一些内容并将其写入文本文件？
