Hi All,

I have a simple xml in database as below.

<test><br />
<testcode>1</testcode><br />
<testdesc>test1</testdesc><br />
</test>

Whenever i save this as a file on my desktop and then load into a dataset, i get the datatable created automatically.

But if i load it into a string and pass it to read, i get an error message saying "Illegal Characters in Path"

Code that I use is

VB

Dim Doc As XDocument = XDocument.Parse(RawXMLStr)
            Sbill.ReadXml(Doc.ToString)

Here
Sbill is my dataset
Rawxmlstr is my string

Any Idea as of how to eliminate this error would be greatly appreciated.

Your simple XML doesn't look correct: last node should be </test>.

It was a Copy error. I have to put everything in code, so i manually typed it again and I missed the "/". But I still have the same problem.

Try again -- now it's valid. (XML prolog is missing, but I don't think this is the problem.)

The XML in your question is valid.

The problem you are experiencing is because the XMLDoc code you tried expects a file path containing xml whereas you passed in xml string content itself.

As for the solution, please see my sample below which works:

XML

String xmlString = "<test><testcode>1</testcode><testdesc>test1</testdesc></test>";

System.Xml.XmlTextReader reader = new System.Xml.XmlTextReader(new System.IO.StringReader(xmlString));
reader.Read();

System.Data.DataSet ds = new System.Data.DataSet();
ds.ReadXml(reader, System.Data.XmlReadMode.Auto);

UPDATE: sorry I realised afterwards your question is VB:

VB

Dim xmlString As String = "<test><testcode>1</testcode><testdesc>test1</testdesc></test>"
Dim reader As System.Xml.XmlTextReader = New System.Xml.XmlTextReader(New System.IO.StringReader(xmlString))
reader.Read()
Dim ds As System.Data.DataSet = New DataSet
        ds.ReadXml(reader, System.Data.XmlReadMode.Auto)
