Hello Everyone,
I have created a form in infopath that i am hosting in a visual studio
2005 project. The XML that is generated from the form gets saved into
a database .. this all works fine. Recently I've added some
functionality onto my project in Visual Studio 2005 c# code and i want
to append an XML node that i create to the XML that is generated from
my form when a certain button clicks. When i try and do this i get an
error ..see below for the code and the error message. I have no idea
what this means or how to fix it. I tried modifying the schema but
that didn't work, also there could be any number of nodes to append.
An example of the nodes to append are:
<Images> -- the parent node, this will always be appended onto the xml
from the form
<Ink>VALUE HERE</Ink>
<Photo>VALUE HERE</Photo> -- there could be zero to many
different ink and photo nodes applied on the fly
</Images>
Error Message:
Schema validation found non-data type errors
Here is the code i use to append the new xmlnode to the xml the form
generates.
XPathNavigator xn =
formControl1.XmlForm.MainDataSource.CreateNavigator();
XPathNavigator navigator =
xn.SelectSingleNode(Constants.MYFIELDS_FIELD, xmlnsm);
XmlElement elementToAppend = prepareXmlNodeForAppend("<Images/>");
navigator.AppendChild(elementToAppend.OuterXml);
------------------------------------
public XmlElement prepareXmlNodeForAppend(string xmlData)
{
XmlDocument xDoc = new XmlDocument();
byte[] bytes = Encoding.UTF8.GetBytes(xmlData);
using (MemoryStream memStream = new MemoryStream())
{
// Load the byte array into the memory stream
memStream.Write(bytes, 0, bytes.Length);
// Load the memory stream into the FormControl
memStream.Seek(0, SeekOrigin.Begin);
xDoc.Load(memStream);
// Close the memory stream
memStream.Close();
}
return xDoc.DocumentElement;
}
