从Python/xm提取信息

Question

这是我的plist/xml（我把它缩短了一点，但它仍然很大，所以我把它作为链接：https://ghostbin.com/paste/rbu9t

我要做的是提取如下字段：

应用标识符
类名
function<；---function=显示名称后的行。你知道吗

我现在得到的是：http://i.imgur.com/X8wlHod.gif

但如果我继续这个模式，它会提取错误的东西。你知道吗

我想能够extarct所有函数和类名为每个应用程序之前，我去下一个。你知道吗

如果这是不可能的，那么我希望能够提取所有类和函数，但是使用plist/xml，它只包含一个应用程序的信息。你知道吗

OLD QUESTION: I'm coding a program, but as you can see, I'm doing +6 then +1, then +6, then +1. Is there a way to automate this (some program or site) or some code to help me? Cheers!

我的代码：（*注意：数字模式并没有我想象的那么有用，因为每个应用程序可以有不同数量的类和函数。你知道吗

import xml.dom.minidom

xml = xml.dom.minidom.parse('my.plist')

Document = xml.getElementsByTagName('plist')



for key in Document:
    desc = key.getElementsByTagName('string')[5].firstChild.data
    desc1 = key.getElementsByTagName('string')[6].firstChild.data

print('Class: ', desc, 'Function: ', desc1)


desc = key.getElementsByTagName('string')[11].firstChild.data
desc1 = key.getElementsByTagName('string')[12].firstChild.data

print('Class: ', desc, 'Function: ', desc1)


desc = key.getElementsByTagName('string')[17].firstChild.data
desc1 = key.getElementsByTagName('string')[18].firstChild.data

print('Class: ', desc, 'Function: ', desc1)

desc = key.getElementsByTagName('string')[23].firstChild.data
desc1 = key.getElementsByTagName('string')[24].firstChild.data

print('Class: ', desc, 'Function: ', desc1)


desc = key.getElementsByTagName('string')[29].firstChild.data
desc1 = key.getElementsByTagName('string')[30].firstChild.data

print('Class: ', desc, 'Function: ', desc1)

对不起，如果帖子不是很详细或解释，如果你有任何问题，我会尽我所能回答他们！你知道吗

Answer 1

使用支持XPath的现代XML库，这要容易得多；因此，我使用下面的^{}。你知道吗

import lxml.etree as etree
import sys

doc = etree.parse(open(sys.argv[1]))
for app_dict in doc.xpath('/plist/dict/array/dict'):
    appId = app_dict.xpath('./key[.="appIdentifier"]/following-sibling::string[1]/text()')[0]
    for method_dict in app_dict.xpath('.//dict[key="methodObjc"]/dict'):
        classId = method_dict.xpath('./key[.="className"]/following-sibling::string[1]/text()')[0]
        methodId = method_dict.xpath('./key[.="displayName"]/following-sibling::string[1]/text()')[0] 
        print 'App: %s; Class: %s; Method: %s' % (appId, classId, methodId)

完整输出为：

Answer 2

x = 5
for key in Document:
    desc = key.getElementsByTagName('string')[x].firstChild.data
    desc1 = key.getElementsByTagName('string')[x+1].firstChild.data
    print('Class: ', desc, 'Function: ', desc1)
    x += 5
