XML 1.1编号版本对xml文档无效

Question

I have a xml document like this

    <?xml version="1.1" encoding="UTF-8" standalone="yes"?>
    <p:FatturaElettronica versione="1.1" xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:p="http://www.fatturapa.gov.it/sdi/fatturapa/v1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <FatturaElettronicaHeader>
            <DatiTrasmissione>
                <IdTrasmittente>
                    <IdPaese>IT</IdPaese>
...

If i use:

Dim doc As New XmlDocument()
doc.Load(filePath)

I receive an error:

1.1 is not a valid version

Why, how can i do for read xml with this version?

Thanks

Give this a try. It assumes that not having the first line has no consequences.

    Dim fileLines As List(Of String) = IO.File.ReadAllLines(filePath).ToList
    fileLines.RemoveAt(0)
    Dim fileAsString As String = String.Join(Environment.NewLine, fileLines)

    Dim xe As XElement = XElement.Parse(fileAsString)

    Dim doc As New XmlDocument()
    doc.Load(xe.CreateReader)

If you download an example of file FatturaPA from http://www.fatturapa.gov.it/export/fatturazione/it/a-3.htm you will notice that xml version is 1.0.

<?xml version="1.0" encoding="UTF-8"?>
<p:FatturaElettronica versione="1.1" xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:p="http://www.fatturapa.gov.it/sdi/fatturapa/v1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

So maybe your file is not correct.
