임의의 XML 예외 - 16 진수 값 0x1F 인 잘못된 문자입니다.

Question

XDocument로로드하려고 할 때 임의의 오류가 발생하여 XML의 잘못된 문자에 대해 불평합니다.

' ', hexadecimal value 0x1F, is an invalid character. Line 1, position 1. 

이러한 21 개 위치 중 하나에서 발생하지만 때로는 그렇지 않습니다. 그것은 BBC의 RSS이므로 엄격하게 관리되고 인코딩 된 XML입니다.

그럼 내 로딩 잠수정 중 하나의 예 :

Public Sub WeatherAviemore_Load() 
    'weatherDoc = XDocument.Load("http://open.live.bbc.co.uk/weather/feeds/en/2656752/3dayforecast.rss") 
    weatherDoc = XDocument.Load(My.Settings.DataMainFolder & "\" & My.Settings.DataWeatherXMLFolder & "\Aviemore.xml") 
    PopulateWeatherListBox(weatherDoc, MainForm.WeatherAviemoreListBox, "Aviemore", "An Aghaidh Mhòr") 
End Sub 

Answer 1

당신이 샘플 주는 XML 문서가 아니므로 메시지가 처음부터 잘못되었다고 메시지에 표시됩니다 (Line 1, position 1). XML 문서는이 (wikipedia)과 같아야합니다 : 나는 파일이 때로는 올바르게 다운로드 때로는하지 않는되어 지금 알고있는 것처럼

<?xml version="1.0" encoding="UTF-8" ?> 
<俄语>данные</俄语> 

편집 . 따라서 가장 좋은 해결책은 사실을 수락하고 다시 다운로드를 시도하는 것입니다. 예를 들어

Dim Success As Boolean = False 
    Do 
     Try 
      weatherDoc = XDocument.Load("http://open.live.bbc.co.uk/weather/feeds/en/2656752/3dayforecast.rss") 
      Success = True 
     Catch ex As XmlException 
      Success = False 
     End Try 
    Loop Until Success 

그리고 어쩌면 또 다른 질문 뭔가 물어 "나는 가끔 open.live.bbc.co.uk/weather에서 쓰레기를 다운로드하고 왜?"
