InfoPath Dev

Hello,
i have a form from my designer, Primary datasource looks like this:
-myFields
|-queryFields
|-dataFields
|-my:test (this is my text filed)
and i can not, get to this, i tried:
IXMLDOMNode test=thisXDocument.DOM.selectSingleNode("my:myFields/my:test");
IXMLDOMNode test=thisXDocument.DOM.selectSingleNode("myFields/test");
and so on... When i use fake namespaces, it creates an error.
When my code is in: 'blablabla=test.text' i get
'Object reference not set to an instance of an object'.
What is going on in here?

Hi mar,

Can you try once this Xpath, Your Xpath should be like “/my:myFields/my:test”.
If above Xpath also doesn#%92t work then you need to set the property of your DOM by using below code:

thisXDocument.DOM.setProperty( "SelectionNamespaces", "Namespace of your DOM");

After this you can try to get the node. And you need to check your Xpath once again.

Hi Shiva,

This did not work for me. Is XDocument the name of the file? Maybe that is why it's not working? Can I send you the xsn file? That may be faster.

Ther is no such method/property in thisXdocument.DOM as setProperty. And this my: prefix doesn't generate an error, any other does.

Hi mar,

I am sorry for I had given above line code. Here is the code for setting the property of the node.

XDocument.GetDOM("DOMName").setProperty("SelectionNamespaces","Namespace of the your DOM");

Can you check once in debug mode if you are getting the DOM and also need to check n that DOM your node is present or not. If your node is present then you have to check once again of your field xpath.

Well, XDocument has only 'Equals' and 'ReferenceEquals properties'. I do not why, but i think, that my problem is caused by queryFields and dataFields. In normal, blank document (not from a data connection), with this structure:
-myFields
|-my:test
IXMLDOMNode test=thisXDocument.DOM.selectSingleNode("my:myFields/my:test"); works perfectly...

I solved my problem.
IXMLDOMNode test=thisXDocument.DOM.selectSingleNode("dfs:myFields/my:test");
works perfectly.
Thanks for your help Shiva.

Mar (or Shiva),

I've been following your conversation here becuase I'm trying to solve the same thing. When you finally solved it Mar, I see that you have "dfs". What is dfs?

Hi Joel Allen,

Here ‘dfs#%92 is the prefix of the node. Each prefix has its own namespace. If you want to change the prefix name also we can change in code, whenever we are setting the property of DOM.
