Hi,

The application wich I developed Save and Load xmls using ClientDataSet. Sometimes the xml files can be updated by third party applications. Often this third party application can make mistakes. Some mistakes the ClientDataSet raise an exception so there's ok, I get the exception and everybody is happy(smile). But some mistakes the ClientDataSet does not raise an exception and does not do nothing !!! It breaks my application. If you wanna cause this problem,
first of all save any ClientDataSet Data to a XML file
After that edit this XML file with notepad and exclude any </ROWDATA> tag
finally try do that ClientDataSet.LoadFromFile(MyFile.xml)

So the error occurs.

How can I solve that?

Thank you very much and sorry my english is begginer yet.

Marco,

You could try loading the doc into a TXMLDocument before loading the
Dataset. This should catch the error in the XML.

Example

procedure TForm1.Button2Click(Sender: TObject);
var
doc : TxmlDocument;
begin
try
doc := TxmlDocument.Create('C:MyXMLFile.xml');
ShowMessage(doc.XML.Text);
finally
doc.Free;
end;
cds.LoadFromFile('C:MyXMLFile.xml');
DataSource1.DataSet := cds;
end;

Sorry Marco I hit the wrong button to reply.
