使用Python minidom读取XML并遍历每个节点 [英] Reading XML using Python minidom and iterating over each node

问题描述

我有一个如下所示的XML结构，但是规模更大:

I have an XML structure that looks like the following, but on a much larger scale:

<root>
    <conference name='1'>
        <author>
            Bob
        </author>
        <author>
            Nigel
        </author>
    </conference>
    <conference name='2'>
        <author>
            Alice
        </author>
        <author>
            Mary
        </author>
    </conference>
</root>

为此，我使用了以下代码:

For this, I used the following code:

dom = parse(filepath)
conference=dom.getElementsByTagName('conference')
for node in conference:
    conf_name=node.getAttribute('name')
    print conf_name
    alist=node.getElementsByTagName('author')
    for a in alist:
        authortext= a.nodeValue
        print authortext

但是，打印出来的作者文本为无".我尝试使用下面的变体来弄乱自己，但是这会导致我的程序中断.

However, the authortext that is printed out is 'None.' I tried messing around with using variations like what is below, but it causes my program to break.

authortext=a[0].nodeValue

正确的输出应为:

1
Bob
Nigel
2
Alice
Mary

但是我得到的是:

1
None
None
2
None
None

关于如何解决此问题的任何建议?

Any suggestions on how to tackle this problem?

推荐答案

您的authortext类型为1(ELEMENT_NODE)，通常需要TEXT_NODE才能获取字符串.这将起作用

your authortext is of type 1 (ELEMENT_NODE), normally you need to have TEXT_NODE to get a string. This will work

a.childNodes[0].nodeValue
