Question

我正在尝试使用.txt文件中的python编写一个xml架构。我尝试了以下代码，但它没有读取文本行中的值。

     The data is like:
      #  File format is Team:Player:Salary:Position
      New York Yankees :"Acevedo Juan"  :   900000: Pitcher
      New York Yankees :"Anderson Jason":   300000: Pitcher 
      ............

和代码：

    import re
    import xml.etree.ElementTree as ET
    root = ET.Element('root')
    root.text = '\n'    # newline before the celldata element
    f = open("C:/baseball.txt")
    lines = f.readlines()
       for l in lines:
           elems = l.split(":")
      if len(elems) == 4:
           elems = map(lambda x: x.strip(), elems)
           playerdata = ET.SubElement(root, "playerdata")
           playerdata.text = '\n'
           playerdata.tail = '\n\n'
           team = ET.SubElement(playerdata, "team")
           player = ET.SubElement(playerdata, "player")
           salary = ET.SubElement(playerdata, "salary")
           position = ET.SubElement(playerdata, "position")
      ET.dump(root)
      tree = ET.ElementTree(root)
      tree.write("test1.xml", encoding='utf-8', xml_declaration=True)

我得到的输出看起来像这样：

     <root>
     <playerdata>
     <team /><player /><salary /><position /></playerdata>

     <playerdata>
     <team /><player /><salary /><position /></playerdata>

     <playerdata>
     <team /><player /><salary /><position /></playerdata>
     .
     .
     .
     <playerdata>
     <team /><player /><salary /><position /></playerdata>

     </root>

一些变化，加上修复。变化是：

使用上下文管理器确保输入文件关闭正确。
使用迭代文件产生每一行的事实转（而不是f.readlines()）。
将线的各部分拆分和剥离合并为一个陈述。

修复方法是在子元素创建后立即设置text值。

import xml.etree.ElementTree as ET
root = ET.Element('root')
root.text = '\n'    # newline before the celldata element
with open("C:/baseball.txt") as f:
   for l in f:
       elems = [ x.strip() for x in l.split(":") ]
       if len(elems) == 4:
           playerdata = ET.SubElement(root, "playerdata")
           playerdata.text = '\n'
           playerdata.tail = '\n\n'
           team = ET.SubElement(playerdata, "team")
           team.text = elems[0]
           player = ET.SubElement(playerdata, "player")
           player.text = elems[1]
           salary = ET.SubElement(playerdata, "salary")
           salary.text = elems[2]
           position = ET.SubElement(playerdata, "position")
           position.text = elems[3]

  ET.dump(root)
  tree = ET.ElementTree(root)
  tree.write("test1.xml", encoding='utf-8', xml_declaration=True)

从txt文件定义XML模式使用Python脚本并将其存储在单个XML文件中
