Android-XML与数转换

Question

InputStream _inputStream = _urlConnection.getInputStream();
                        BufferedInputStream _bufferedInputStream = new BufferedInputStream(_inputStream);
                        ByteArrayBuffer _byteArrayBuffer = new ByteArrayBuffer(64);

                        int current = 0;
                        while((current = _bufferedInputStream.read()) != -1)
                        {
                            _byteArrayBuffer.append((byte)current);
                        }

                        FileOutputStream _fileOutputStream = openFileOutput(_file, MODE_PRIVATE);

                        _fileOutputStream.write(_byteArrayBuffer.toByteArray());
                        _fileOutputStream.close();

在endElement中使用Sax转换数据

else if (inLocalName.equalsIgnoreCase(_nodeTitle))
        {
            _titleValue = currentValue;
            currentValue = "";
        }

在debug中，当我在处理程序中的characters方法中读取它时，已经转换了与数，并且数据被截断了。

我见过很多关于这个的问题，但从来没有解决办法。有什么想法吗？

List<PropertiesList> _theList = null;

        try 
        {
            // Create Factory, Parser, Reader, Handler
            SAXParserFactory _saxParserFactory = SAXParserFactory.newInstance();
            SAXParser _saxParser = _saxParserFactory.newSAXParser();
            XMLReader _xmlReader = _saxParser.getXMLReader();
            HandlerReps _handler = new HandlerReps(inRegion, inAbbreviation);

            _xmlReader.setContentHandler(_handler);
            _xmlReader.parse(new InputSource(inStream));

            _theList = _handler.getTheList();
        } 

// Called when Tag Begins
    @Override
    public void startElement(String uri, String inLocalName, String inQName, Attributes inAttributes) throws SAXException 
    {
        currentElement = false;
    }

    // Called when Tag Ends
    @Override
    public void endElement(String inUri, String inLocalName, String inQName) throws SAXException 
    {
        currentElement = false;

        // Title
        if (inLocalName.equalsIgnoreCase(_nodeValue))
        {
            if (_stateValue.equalsIgnoreCase(_abbreviation) && 
                _countryValue.equalsIgnoreCase(_region))
            {
                // Construct the object
                PropertiesRegion _regionObject = new PropertiesRegion(_titleValue, _address1Value);

                cList.add(_regionObject);

                Log.d(TAG, _regionObject.toString());
            }

            _titleValue = "";
            _address1Value = "";
        }

        // Title
        else if (inLocalName.equalsIgnoreCase(_nodeTitle))
        {
            _titleValue = currentValue;
            currentValue = "";
        }

        // Address1
        else if (inLocalName.equalsIgnoreCase(_nodeAddress1))
        {
            _address1Value = currentValue;
            currentValue = "";
        }
    }

    // Called to get Tag Characters
    @Override
    public void characters(char[] inChar, int inStart, int inLength) throws SAXException 
    {
        if (currentElement) 
        {
            currentValue = new String(inChar, inStart, inLength);
            currentElement = false;
        }
    }

Answer 1

这很有可能是导致您问题的原因：

    if (currentElement) 
    {
        currentValue = new String(inChar, inStart, inLength);
        currentElement = false;
    }

对于每个文本内容节点，SAX解析器可能会向您的处理程序发送多个characters（）事件。只有将所有这些事件串联起来，才会得到整个文本。但是在您的代码中，只使用这些事件中的第一个，因为然后您设置currentElement=false。

问题不是和数转换。作为一般规则，当你描述一个问题时，通常只描述症状更好，而不是任何假定的原因。
