使用xml时获取正确值时出现问题。

Question

我正在尝试从xml文件导出所有电影标题，但似乎无法获取标题。xml看起来像：

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<videodb>
    <version>1</version>
    <movie>
        <title>2 Guns</title>
        <originaltitle>2 Guns</originaltitle>
        <ratings>
            <rating name="themoviedb" max="10" default="true">
                <value>6.500000</value>
                <votes>1776</votes>
            </rating>
        </ratings>

我已经看到了很多xml有value="title"的值的示例，但是找不到一个在没有value="title"时有效的指导示例

到目前为止，我的代码是：

#Import required library
import xml.etree.cElementTree as ET
root = ET.parse('D:\\temp\\videodb.xml').getroot()

for type_text in root.findall('movie/title'):
    value = type_text.get ('text')
    print(value)

Answer 1

XML文件：

<?xml version="1.0" encoding="utf-8"?>
<videodb>
    <version>1</version>
    <movie>
        <title>2 Guns</title>
        <originaltitle>2 Guns</originaltitle>
        <ratings>
            <rating name="themoviedb" max="10" default="true">
                <value>6.500000</value>
                <votes>1776</votes>
            </rating>
        </ratings>
    </movie>
    <movie>
        <title>Top Gun</title>
        <originaltitle>Top Gun</originaltitle>
        <ratings>
            <rating name="themoviedb" max="10" default="true">
                <value>7.500000</value>
                <votes>1566</votes>
            </rating>
        </ratings>
    </movie>
    <movie>
        <title>Inception</title>
        <originaltitle>Inceptions</originaltitle>
        <ratings>
            <rating name="themoviedb" max="10" default="true">
                <value>9.500000</value>
                <votes>177346</votes>
            </rating>
        </ratings>
    </movie>
</videodb>

代码：

import xml.etree.ElementTree as ET
tree = ET.parse('E:\Python\DataFiles\movies.xml') # replace with your path
root = tree.getroot()
for aMovie in root.iter('movie'):
    print(aMovie.find('title').text)

输出：

2 Guns
Top Gun
Inception

Answer 2

尝试替换：

value = type_text.get ('text')

与

value = type_text.text

xml.etree使用^{}检索内容元素属性

您正在查找元素文本；见Element.text

例如，考虑到这种人为设计的XML：

<element some_attribute="Some Attribute">Some Text</element>

.get('some_attribute')将返回Some Attribute，而.text将返回Some Text
