.NET Forum / ASP.NET / Web Services / September 2004Ampersands in the result, xmldatadocument
I am returning an XMLDataDocument in my service since my client cannot consume the dataset. The resulting XML does not replace ampersand characters in the string values with & - for example - <field>David & David</field> The clients parser chokes on that. Is there something I can do with the XMLDataDocument to replace such characters?  SignatureDavid Bartosik - MS MVP www.publishermvps.com Hi David, As for the XmlDataDocument, generally if you are using .net framework at both client and serverside, it'll auto escape and descape those characters. What's the client you used to consume the webservice? In addition, I think you can try using the CDataSection to wrapper the certain field which may contain those charaters. We can use the XmlDataDocument's "CreateCDataSection" method to create a XmlCDataSection and insert into the document. #XmlCDataSection Class http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/ frlrfsystemxmlxmldatadocumentclasstopic.asp #XmlDocument.CreateCDataSection Method http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/ frlrfsystemxmlxmldatadocumentclasstopic.asp Regards, Steven Cheng Microsoft Online Support SignatureGet Secure! www.microsoft.com/security (This posting is provided "AS IS", with no warranties, and confers no rights.) The client is using Axis. Java. I tried a typed dataset but they don't seem to know what they would need to do with that so that's why I'm trying the XML now. But they now say their parser chokes on any special characters. Is this your only suggestion ?

Hi David, As for the special characters, I think it is likely due to the different implementing on soap message of the axis and .net framework webservice. If both the client and server use the .net framework the speical characters will be processed correctly internally. But as for the axis, since it is not designed right compatible with .net , I think it better to use CData Section to ensure the text data be escaped.
