是共享点Web服务的响应，该Web服务试图读取csv文件并给出了这样的响应。如您在上面的响应xml中看到的那样，csv数据确实出现了，但是在一个名为<message-body>的xmltag中，并且在每行格式之后也丢失了新行！
现在我需要重新创建csv !!。最糟糕的是，在我收到这种格式的工具中，我有能力编写xslt和xml！不能使用托管语言代码或库。 也只有xslt 1.0。
有这样的问题 question on creating csv from xml，但这与我的要求有些不同。我只是在学习xslt和xpath，在这方面有人可以帮助我吗？
以下是请求的输出： click here to view the csv format
答案 0 :(得分：1)
如果人们假设标题行以冒号结尾，并且每个数据行中有7个值*，则可以使用以下样式表：
XSLT 1.0
public void ReceiveFromGattCharacteristic(string service, string characteristic, string descriptor = null)
{
DebugHelper.Message(Type.Method, "ReceiveFromGattCharacteristic");
bleAdapter.DeviceConnected += async (s, e) =>
{
try
{
DebugHelper.Message(Type.Info, "bleAdapter.DeviceConected += async (s, e) ...");
string[] deviceInfo = { e.Device.Name, e.Device.Id.ToString() };
// Connect to service
try
{
DebugHelper.Message(Type.Info, "Connecting to service...");
_service = await e.Device.GetServiceAsync(Guid.Parse(service));
DebugHelper.Message(Type.Info, "OK");
}
catch (Exception)
{
DebugHelper.Error(ErrorType.GATT, "Could not connect to service");
}
// Connect to characteristic
try
{
DebugHelper.Message(Type.Info, "Connecting to characteristic...");
_characteristic = await _service.GetCharacteristicAsync(Guid.Parse(characteristic));
DebugHelper.Message(Type.Info, "OK");
}
catch (Exception)
{
DebugHelper.Error(ErrorType.GATT, "Could not connect to characteristic");
}
await ConfigureSpectrogram(UpdateFrequency.High, 0x1);
try
{
await _characteristic.StartUpdatesAsync();
}
catch
{
DebugHelper.Error(ErrorType.GATT, "Error starting UpdatesAsync");
}
// ADDITION
_characteristic.ValueUpdated += (o, args) =>
{
var raw = args.Characteristic.Value;
Xamarin.Forms.Device.BeginInvokeOnMainThread(() =>
{
DataPageViewModel.Levels.Clear();
for (int i = Models.Spectrogram.FrequencyOffset; i < raw.Length; i++)
{
if (SettingsViewModel.IsViewRawData)
{
DataPageViewModel.Title = "Raw data";
DataPageViewModel
.Levels
.Add(
new Models.Spectrogram(
raw[i],
1 + (i - Models.Spectrogram.FrequencyOffset))
);
}
if (SettingsViewModel.IsViewProcessedData)
{
DataPageViewModel.Title = "Processed data";
DataPageViewModel
.Levels
.Add(
new Models.Spectrogram(
raw[i],
1 + (i - Models.Spectrogram.FrequencyOffset),
i));
}
}
});
};
}
// END OF ADDITION
catch (Exception)
{
DebugHelper.Error(ErrorType.GATT, "Error in ReceiveFromGattCharacteristic");
}
};
}
应用于您的输入示例，结果将是：

这可能需要更多的工作来处理带引号的值中可能的转义双引号。
-
（*）奇怪的是，标题行中有8个值，而数据行中只有7个值。
