存储XML，XML中更新记录，检索存储BB设备上的XML特定记录 [英] Store XML, update record in XML, retrieve a specific record in XML stored on BB device
问题描述
我写一个黑莓应用程序，我想存储
通过Web服务在我的BB器返回的数据。早些时候，我去
使用SQLite存储在移动，但作为数据我一派，也没有使用SQLite编程，发现
有些BB设备不支持SQLite库而无法创建数据库。然后，我决定继续
该数据通过Web服务返回的XML格式，我的BB设备上。
I am writing a blackberry application where I want to store the data returned by a web service in my BB device. Earlier I was going to use SQLite for storing the data in mobile but as I googled and also did programming using SQLite and found that some BB devices don't support SQLite library and fail to create the database. Then I decided to keep the data returned by webservice in a XML format on my BB device.
我只是想知道有没有通过黑莓的任何方法或方式
我可以解析存储在XML数据，更新，或者直接访问
存储在XML，而不是遍历整个XML n次，并找到匹配的记录的特定记录。
I just want to know is there any method or way in blackberry through which i can parse the data stored in XML, update it, or directly access a particular record stored in the XML instead of traversing the whole XML n times and finding the matched record.
请指引我，因为我是新来的BB设备中存储的数据。是的做法，
我想到的是存储数据的XML权利或我应该用别的东西吗？
Please guide me as I am new to storing data in BB device. Is the approach which I am thinking to store data in XML right or shall I use something else?

1) RMS - better to use if u r using midlets 2) Persistence - for cldc 3) Sqlite - devices supporting OS 5.0 or later 4) File system - any device
持久性：当u得到你的XML响应尝试分析并从中获取组件，保存在一个载体，坚持device.You的向量可以从它的任何时候获取数据
Persistence: when u get your response in xml try to parse and fetch the components from it, save in a vector and persist that vector in device.You can fetch data from it any time.
