XML pull解析器资产XML [英] xml pull parser assets xml

问题描述

如何解析的资产中的本地XML文件夹使用pull解析器？我不能让拉解析器可以工作。它总是抛出IO异常。我想，我不能让文件路径，或连接到该文件。

How can i parse a local XML file in the assets folder using pull parser? I can't get pull parser to work. It always throws an io exception. I think I can't get the path to the file, or connecting to the file.

推荐答案

mixm，

我是问各种方式从两个'资产'和'水库'加载本地文件，但回答你的问题被玩弄（因为没有其他人似乎有）：

I was toying with various ways to load a local file from both 'assets' and 'res', but to answer your question as asked (as no one else seems to have):

首先，可以确保你的XML是在测试前有效或关闭验证，这是你如何能做到这一点，实例化一个pull解析器在同一时间：

First, either make sure your XML is valid before testing or turn off validation, this is how you can do that and instantiate a pull parser at the same time:

    try {
        XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
        factory.setValidating(false);
        XmlPullParser myxml = factory.newPullParser();

然后打开XML文件，并设置为输入到你的拉解析器：

Then open the xml file and set as input to your pull parser:

        InputStream raw = getApplicationContext().getAssets().open("simple.xml");
        myxml.setInput(raw, null);

现在设置您的拉环（或其他，取决于你是否要推迟做拉或不，这是你的设计决策：

Now setup your pull loop (or other, depends on whether you want to do deferred pulling or not, that's your design decisions:

        int eventType = myxml.getEventType();
        while(eventType != XmlPullParser.END_DOCUMENT) {
            if(eventType == XmlPullParser.START_DOCUMENT) {

                Log.d(MY_DEBUG_TAG, "In start document");
            }
            else if(eventType == XmlPullParser.START_TAG) {
                Log.d(MY_DEBUG_TAG, "In start tag = "+myxml.getName());
            }
            else if(eventType == XmlPullParser.END_TAG) {
                Log.d(MY_DEBUG_TAG, "In end tag = "+myxml.getName());

            }
            else if(eventType == XmlPullParser.TEXT) {
                Log.d(MY_DEBUG_TAG, "Have text = "+myxml.getText());
            }
            eventType = myxml.next();
        }
    } catch (XmlPullParserException e) {

注意 myxml.getEventType（），你需要做到这一点得到了解析会，处理什么类型的事件，你是拉。注：省略了可读性catch块

Note the myxml.getEventType() , you need to do this to get the parse going and handle what type events you are pulling. Note: catch blocks omitted for readability.
