How to find a node using expressions

If your main data source contains hundreds of nodes, how will you find one using expressions? Suppose "Nodes" is the parent node with the following xpath:

XPathNavigator nodes = this.CreateNavigator().SelectSingleNode("/my:myFields/my:Nodes", this.NamespaceManager);

To find nodes inside "Nodes" (parent node), do the following

nodes.SelectSingleNode("child::*[contains(name(),"abc")]");

This will select the child node that has "abc" in its name. This is just an example and can have many practical uses.

Validating contact selector control programmatically

How to know if contact selector is empty?

XpathNavigator selector = this.CreateNavigator().SelectSingleNode("/my:myFields/my:contactselector", this.NamespaceManager);

if (selector.SelectChildren(XPathNodeType.Element).Count == 0)
{
this.Errors.Add(selector, "Error","Selector is empty");

}

How to raise error if user has selected more than one person in the selector?

if (selector.SelectChildren(XPathNodeType.Element).Count > 1)
{
this.Errors.Add(selector, "Error","Please select one user");

}

How to tell if user hasn't selected a valid person?

  selector = selector.SelectSingleNode("my:Person", this.NamespaceManager);

XPathNavigator displayname = this.CreateNavigator().SelectSingleNode("/my:myFields/my:contactselector/my:Person/my:DisplayName", this.NamespaceManager);
string strDisplayName = displayname.value.toString();

XPathNavigator accountid = this.CreateNavigator().SelectSingleNode("/my:myFields/my:contactselector/my:Person/my:AccountId", this.NamespaceManager);
string strAccountid = accountid.value.toString();

XPathNavigator accounttype = this.CreateNavigator().SelectSingleNode("/my:myFields/my:contactselector/my:Person/my:AccountType", this.NamespaceManager);
string strAccountType = accounttype.value.toString();

                    if (string.IsNullOrEmpty(strDisplayName)) ||
                        string.IsNullOrEmpty(strAccountId)) ||
                        string.IsNullOrEmpty(strAccountType))
                    {
                         this.Errors.Add(selector,"Error","Please select valid user");
                    }

Note: This was off the top of my head, you may find minor mistakes in XPaths or spellings.

InfoPath: Copying content of one section to another

If you have two sections (sections can have anything including file controls) and you want to copy content from one section to another, here is how you do it:

string sourceXPath = "/my:myFields/my:Source";

string destXPath = "/my:myFields/my:Destination";

 XPathNavigator source = this.CreateNavigator().SelectSingleNode(srcXPath, this.NamespaceManager);
            XPathNavigator dest = this.CreateNavigator().SelectSingleNode(destXPath, this.NamespaceManager);

            if (dest.MoveToAttribute("nil", "http://www.w3.org/2001/XMLSchema-instance"))
                dest.DeleteSelf();

            if (source.InnerXml.Contains("xsi:nil="))
            {
                //Do nothing
            }
            else
            {
                if (dest.InnerXml.Contains("xsi:nil="))
                {
                    dest.InnerXml = source.InnerXml;
                }
                else
                {
                    dest.InnerXml += source.InnerXml;
                }
