[RESOLVED] Ignore DocType when using System.Xml.XmlDocument

[NotLKH]

Using VBNet 2002:

Any idea how I can get System.Xml.XmlDocument to ignore the !DocType referance in an XML string, without just deleting the offending referance prior to .LoadXml ?

Error Message: Could not find file "C:\Documents and Settings\lou\My Documents\Visual Studio Projects\Micro_Manage_AutoSubmit\bin\xpif-v2000.dtd".

            '    End If
            'End If

Could you get the data into a temporary string and then replace it with nothing, thus not affecting the actual original file.

Good Idea!

Thats what this does, when uncommented:

'mSpot1 = mPrepend.IndexOf("<!DOCTYPE xpif SYSTEM ")
            'If mSpot1 > -1 Then
            '    mSpot2 = mPrepend.IndexOf(mStrip2, mSpot1)
            '    If mSpot2 > -1 Then
            '        mStrip3 = mPrepend.Substring(mSpot1, mSpot2 + mStrip2.Length - mSpot1)
            '        mPrepend = mPrepend.Replace(mStrip3, "")
            '    End If
            'End If

I just don't like it, as its fudging around the issue.

I was hoping there might be a .UseDocType switch of some sort, as that would be more elegant.

Try setting the XmlResolver of the xml document to Nothing before calling LoadXml

Bingo!
