Question

我得到了这段代码，一个.plist。有没有办法提取它的某些部分？我只想要字符串，如果可能的话，只需要一些特定的字符串。

就像我可以提取-(bool) isAgent一样知道<key>displayName</key>位于其上方，<key>prefix</key>位于其下方。

                <string>ZDKUser</string>
                <key>displayName</key>
                <string>-(bool) isAgent</string>
                <key>prefix</key>

在这个区块之外^

这可能吗？我该怎么办？如果用python不可能，怎么回事？

import lxml.etree as etree

for app_dict in doc.xpath('/plist/dict/array/dict'):

        print 'App: %s; Class: %s; Method: %s' % (appId, classId, methodId)
