Error in parsing xml with navision

subhaster

Hi !
I am getting an error, when I am trying to read an XML file . The function body for reading an xml looks like this :-

XmlNodeList := XmlDom.getElementsByTagName('first');
XmlNode := XmlNodeList.item(0);
VMsg:=XmlNode.selectNodes('msg').item(0).text;
MESSAGE(VMsg);

where XMLNodeList is an automation datatype with the subtype as 'Microsoft XML, v4.0'.IXMLDOMNodeList
XML Node is also automation datatype with subtype as 'Microsoft XML, v4.0'.IXMLDOMNode

The error is like this :-
This message is for the C/AL programmers :-
You must instantiate/assign the automation variable.

If someone can throw some light on this , it would be of extreme help for me.

On top of your code you have to enter
If isclear(xmldom) then
Create(xmldom);

Yup, i wrote that at the top of the code. but still it is giving me the error.

Turn on the debugger and see where it stops.

My guess it stops
XmlNode := XmlNodeList.item(0);

which means XmlDom.getElementsByTagName('first'); returns a null.

Make sure 'first' is a xml tag.

in the xml file
<first> something</first>


If you put your xml file structure it would help.

Yes Rashid, you are right ....
i ,by mistake, was passing an xml file like this :-
<first><msg>this is test</msg></first>
in to the message queue. But unfortunately, it was apparently an XML file , but actually , it was getting sent in to the MSMQ as a text file.
As a result , <first> was not a tag !

Thanks !

I am glad that your was resolved.
